3 It is suitable for leather Paint Home News: Product Introduction: Insecticidal paint is a functional paint After indoor insects contact with this kind of paint, the nervous system will be damaged and paralyzed, leading to death Insecticidal coating can not only be used in residential buildings, offices, hotels, restaurants, schools, factories, warehouses, but also in the interior wall decoration projects of hospitals, restaurants, medicine and health, food processing, etc In Japan and Europe, insecticidal coating, as a multi-functional special coating product, has been widely used Classification: Mechanism: Insecticidal coating is to achieve its insecticidal purpose by playing the efficacy of insecticides in the coating Insecticidal coating is porous, similar to pores on human skin, through which water can pass In the process of film formation, chemicals with insect killing function pass through these pores with water When the water evaporates, crystals are formed on the surface of the coating Once the insects contact the coating surface, the insect killing crystals can dissolve the fat feet of the insects, destroy the nervous system of the insects, paralyze or even kill the pests This kind of contact killing method is relatively safe for human and livestock, with good insecticidal effect and long duration of efficacy Features: 1 Colorful, elegant and holy decoration effect is also praised by people, and relevant experts can produce a variety of colors according to the needs of users; 2 At present, the most scientific, effective and pollution-free insecticide method of insecticide coating, which is called "all-around coating" integrating decoration, environmental protection and health in the world Scope of application: in addition to the decoration and protection functions of general architectural coatings, insecticidal coatings can also kill flies, mosquitoes, cockroaches, pruritus, bedbugs, spiders and other pests, which can be widely used in residential, hospital, hotel, office building, public toilet, warehouse, vehicle and ship, food factory, Hotel and theater and many other occasions Composition: common coating system is composed of film-forming base material, pigment, filler, auxiliary agent, solvent, etc., of which the choice of good film-forming base material is very important The commonly used insecticides are divided into six categories: ① organic chloride; ② organic tin; ③ organic metal salt; ④ organic phosphorus; ⑤ carbamate; ⑥ pyrethroid Performance test: To evaluate the performance of insecticidal coatings, usually from three aspects, namely, the physical and chemical properties, insecticidal effect and safety of coatings and their coatings Production process: sample formulation: raw material mass fraction /%, pure acrylic emulsion 5 - 28 pigment filler 48 - 50 dispersant 0.2 - - 0.4 - film forming agent 0.8 - 1 preservative 0.1 - 0.2 propylene glycol 5.5 - 0.2 compound insecticide less than 0.2 thickening agent - - water - - - According to the requirements of the coating formula, a certain amount of water is added into the dispersion tank, a dispersant is added into the low-speed mixing, and then titanium dioxide powder, heavy calcium carbonate, talc powder and wollastonite are added in turn to disperse at high speed (30- 50) after adding min, the compound insecticide slow release agent mixed with sepiolite was mixed with high speed dispersing (5~10) min and then transferred to low speed stirring state In addition, emulsion, film builder, thickener and leveling agent were added to the low speed stirring to form insecticidal coatings Coating method: brush, roll or spray Maintenance period: 7 days the best base conditions: 1 The quality of concrete or plastering base of new buildings shall comply with GB 50210-2001 code for acceptance of quality of building decoration engineering 2 The base surface shall be clean, dry, free of any dirt, flat, solid, and free of looseness and peeling 3 If the construction wall needs to be leveled, high-quality external wall putty shall be applied to ensure the construction quality 4 The pH value of the construction wall shall be less than 9.5, the moisture content of the base course shall be less than 10%, the new powder cement mortar wall shall be cured for more than 10 days in summer, more than 20 days in winter, the cast-in-place concrete wall shall be cured for more than 21 days in summer, and more than 28 days in winter, so as to prevent the paint film from being damaged by strong alkalinity 5 If there is an old paint film on the wall, and the paint film is solid and complete, it can be painted directly If the old paint film is loose, powdered or peeled off, it must be completely removed before painting and refreshing the coating Construction conditions: construction temperature > 5 ℃, humidity < 85% Storage: store in a cool and dry place at 0 ℃ ~ 40 ℃ Development trend: Insecticidal coating can be applied on the wall and ceiling as common coating, which is a functional coating integrating decoration and health With the development of coating and insecticide manufacturing technology and people's gradual understanding of the performance of insecticidal coating, insecticidal coating will get faster development Looking forward to the future of insecticidal coatings, it will present the following development trends 1 The premise of developing green and environmental friendly insecticidal coatings is that both pesticides and coatings are harmless to the environment and human body It is mainly realized by high efficiency and low toxicity of insecticides and low VOC of coatings High efficiency and low toxicity insecticides mainly consist of scientific and organic compounding of single insecticide and adding a certain amount of Chinese herbal medicine appropriately There are three ways to reduce VOC content in coatings: ① replacing VOC with water; ② increasing solid content; ③ developing powder coatings The green and environment-friendly insecticide coating can be prepared by using the high-efficiency and low toxicity active insecticide formula and the advanced coating formula which meet the environmental protection requirements, and combining the active insecticide and the coating components with scientific methods 2 To improve the application time of insecticides in coatings, because the mechanism of insecticide coating is contact insecticide, insecticides can be separated out or permeated through the coating surface, and the purpose of insecticide is achieved due to the contact of insects In order to improve the application time of insecticides in coatings, diatomite or attapulgite or sepiolite with strong adsorption can be properly added into coatings as slow-release carriers to absorb insecticide solution Before the coating, the carrier of slow-release agent is evenly distributed in the coating The active components of insecticide in the solution adsorbed by the carrier migrate to the surface of the coating for crystallization, exposing the insecticide group to the outside without being wrapped by the pigment and filler After the coating is formed, the active components of insecticide in the carrier of slow-release agent are continuously separated out through the existing channels to poison the insects in contact with it Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
