Coating classification: water based coating for paper

Core tip: Introduction: Paper coating is a kind of varnish, which is suitable for the coating and decoration of book cover, advertisement picture, commodity outer packing box, decorative paper bag, etc to enhance the aesthetic feeling of the coated objects The previous paper covering method is to stick a layer of polyethylene or polypropylene film on the paper The construction process includes gluing, laminating, etc it also needs to wait for the interlayer adhesive to solidify The overall production efficiency is low, the construction technology requirements are high, and the durability of the plastic film is difficult to guarantee When the product is used for a long time, the laminating is easy to start to peel from the corner Solvent based and water-based paper Polish also has a small market, but both exist Paint knowledge how about Akzo Nobel Powder Coating Recommended introduction: powder coating is a kind of coating with different form from general coating, which is in powder form It is a new type of coating, because of its own advantages and more and more known by people Let's introduce Akzo Nobel Powder coating Akzo Nobel Powder coating is a cost-effective coating solution, which can be applied to different kinds of products After the treatment of static electricity and fire baking, a tough and durable coating surface will be formed, with the least impact on the environment Since the introduction of this technology, powder coating has been able to continue to maintain the Coating home news: Introduction: paper coating is a kind of varnish, which is suitable for the coating and decoration of book cover, advertising posters, commodity outer packaging cartons, decorative paper bags, etc., to enhance the aesthetic feeling of the coated objects The previous paper covering method is to stick a layer of polyethylene or polypropylene film on the paper The construction process includes gluing, laminating, etc it also needs to wait for the interlayer adhesive to solidify The overall production efficiency is low, the construction technology requirements are high, and the durability of the plastic film is difficult to guarantee When the product is used for a long time, the laminating is easy to start to peel from the corner Solvent based and water-based paper Polish also has a small market, but there are problems such as base material wetting deformation, long drying time and so on, which do not form a large production scale In many aspects, such as construction technical requirements, production efficiency and cost, the varnish on the light cured paper is superior to the plastic film covering process, so as to become one of the largest production varieties of light cured products The largest production of UV curable paper coating is high gloss varnish, which aims to improve the glossiness of the printing surface With the change of people's concept, there are many Polish oils with special effects, such as sanding, matte, super smooth, ice flower, wrinkles, pearlescent, bronzing and so on The high gloss paper varnish is still widely used, but the current popular thing is to partially cover it with silk screen printing Printed on the paper pattern, highlighting the local beautification effect Production: O formulation design, O synthesis process, emulsion polymerization was used to prepare water soluble resin for Waterborne Varnish, and potassium persulfate was used as initiator, and core shell structure emulsion particles were prepared by seed polymerization to control the morphology and size distribution of emulsion particles In the three bottle with agitator, thermometer and condensing tube, first add the acrylic resin with acid value of 230 mg KOH / g and molecular weight of 6000 to prepare 30% aqueous solution Then add all water, emulsifier and 10% monomer at one time according to the preparation, stir and apply nitrogen Heat up to 70 degrees Celsius, add potassium persulfate initiator, stir to the blue light of the emulsion, raise the reaction temperature to 80 degrees, add the remaining monomer in 2 h, heat the emulsion for 1.5 h, cool the emulsion to 40 C, add ammonia water to adjust the pH value to 7-8180 mesh mesh filtration, then get the styrene acrylic emulsion Mix the above components evenly to get the product Performance: application: water-based coating for paper offset glazing 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,
