Coating classification: antiskid agent for coating

Core tip: Introduction: antiskid agent for coating is an additive to improve the antiskid performance of the coating, which can give the coating antiskid ability and achieve the required antiskid degree Application mechanism: the action mechanism of antiskid agent for coating is as follows: The function of antiskid agent for coating is opposite to that of antiskid agent, which is to improve the friction coefficient of coating on the second surface, such as rubber, wood, glass, PVC, polyethylene and other surfaces After the antiskid agent is added into the coating and the coating is cured, the anti-chemical skill is slightly protruding from the coating surface, which is in the form of micro relief, mechanically endowing the coating surface with appropriate roughness, thus hindering Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Introduction: antiskid agent for coating is an additive to improve the antiskid performance of the coating, which can give the coating antiskid ability and achieve the required antiskid degree Application mechanism: the function mechanism of antiskid agent for coating is as follows: the function of antiskid agent for coating in coating is just opposite to that of antiskid agent for increasing the friction coefficient of coating on the second surface, such as rubber, wood, glass, PVC, polyethylene and other object surfaces After the antiskid agent is added into the coating and coated and solidified, the antiskid skill is slightly protruding from the coating surface, which is in the form of micro relief It mechanically endows the coating surface with appropriate roughness, hinders or resists the movement of the second surface on it, so as to achieve the antiskid effect When the surface is wet (with water or oil), the coating is also required to have certain skid resistance Main categories: commonly used antiskid agents for coatings can be divided into two categories according to their materials ① Synthetic organic materials such as PVC, PE, PP resin particles, polyurethane resin particles, rubber particles and other inert polymer materials The necessary condition for the use of synthetic organic materials is that they cannot be used in the coating solvent ② Inorganic substances such as silica sand, quartz sand, glass, silicon carbide (trade name emery), crystalline alumina, mica, lead powder, mica like iron oxide, etc According to different requirements, antiskid agents need to be processed into different shapes (round, flat or amorphous) and different particle sizes Generally speaking, the antiskid agent not only gives the film antiskid property, but also makes the film wear-resistant Usage: in the coating, there are several ways to use antiskid agent, all of which can get antiskid coating, but each has its own advantages and disadvantages ① The direct addition method is simple and easy to operate, and is often used in coatings, but the distribution of antiskid agent particles is difficult to be uniform ② This coating method covers all antiskid particles, fills all cracks and cavities, and avoids "polluting" the surface But its disadvantage is that the main task of antiskid agent is to give the film antiskid property ③ The mixed antiskid agent particles are wetted with the coating base material in advance and mixed into the coating to form a mobile component When the film is formed during construction, the coating solidifies with time The antiskid agent particles are connected by the solidified intermediate film layer ④ The method adopts hollow microsphere antiskid agent particles When the coating is applied to the last finishing coat, and the finishing coat is not solidified and in a flowing state, the hollow antiskid agent particles are distributed freely or squeezed into the surface of the paint film by mechanical force such as spray gun With the drying and solidification of the paint film, the hollow particles are embedded into the surface of the paint film, and then the surface is broken by mechanical action (such as severe friction with rough emery paper) or chemical erosion or thermal shock And / or partially remove the embedded hollow bead particles, so that the surface is a micro relief type, giving the coating antiskid The reason why the hollow particle crushing method can make the film antiskid is that the surface friction or other effects cause the following two results a As a result, the hollow particles are broken, leaving a serrated edge on the coating surface that can only be observed with a microscope, which hinders the movement of the second surface on the coating surface b As a result, some hollow particles are completely separated from the coating, leaving holes or micro pits on the coating surface that can only be observed with a microscope These holes or micro pits are equivalent to increasing the roughness of the coating surface, thus making the coating antiskid And these caves or pits are like tiny "empty suction cups" When the coating surface is wet, it is filled with water or oil, so that the coating still has skid resistance In the process of using the antiskid surface obtained by the hollow particle crushing method, the new hollow particles can be broken or removed continuously after abrasion and friction, and the new coating surface similar to the initial coating surface is exposed Therefore, the antiskid property of the coating obtained by this method can basically maintain the whole service life of the coating The hollow particles are in the shape of microsphere, whose wall thickness is much smaller than its diameter, and are broken by friction or other effects The material can be glass, ceramic, plastic, metal, etc Of course, the antiskid surface formed by this method has micro pits and micro "pits" to contain dust and dirt, so the home of "contaminated" coatings is focused on coatings, diatom mud, paint coating, coating process, news information and coatings of fireproof coatings,
