It is suggested that water-soluble resin coating mainly uses water-soluble resin as film-forming material The key to prepare water-soluble resin coating is that the film-forming material can be soluble in water, and the coating can resist water after construction Since most synthetic resins are insoluble in water, the structure of the resin should be modified to achieve the purpose of water-soluble The method is as follows: firstly, introduce hydrophilic polar groups in the resin structure, such as common hydroxyl group, amino group, carboxyl group, acylamino group, etc., the resin thus obtained is only hydrophilic but not water-soluble If the resin introducing hydrophilic groups is introduced into the resin containing carboxyl group, further neutralize it with ammonia to form salt Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Coating home news: water soluble resin coating mainly uses water-soluble resin as film-forming material The key to prepare water-soluble resin coating is that the film-forming material can be soluble in water, and the coating can resist water after construction Since most synthetic resins are insoluble in water, the structure of the resin should be modified to achieve the purpose of water-soluble The method is as follows: firstly, introduce hydrophilic polar groups in the resin structure, such as common hydroxyl group, amino group, carboxyl group, acylamino group, etc., so that the resin obtained is only hydrophilic and cannot be water-soluble If the resin introducing hydrophilic groups is introduced into the resin containing carboxyl group, further neutralize it with ammonia to form salt, then water-soluble can be obtained Through such treatment, the key problem of water solubility of synthetic resin for coating is solved 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,
