container water-based acrylic paint development
pick:
developed a water-based acrylic paint used in containers.
acrylic emulsion with different glass transition temperatures is used as a film-forming substation, pigment fillers and suitable water-based paint additives are added to prepare water-based acrylic finishes.
focus on different acrylic emulsion ratio, paint face ratio, fast-drying solvent dosage, thickener type and type, as well as desiccant and other effects on

.
through orthographic testing, the final development of high-performance water-based acrylic paint, in line with the China Container Association (CCIA) organization of JH/T E08-2015 "container water-based coating coating testing methods and acceptance standards."

solvent-free anti-corrosion waterproof The research and development
coatings should be extracted:
The use of polytianmen anti-urethane resin, additives, insulated thermal fillers, flame retardants, water repugnants and pigments, such as the preparation of solvent-free insulation anti-corrosion waterproof coating A component, with the adipose isocyanate NX-100 curing agent B component with a quality ratio of 4:1 prepared a solvent-free insulation waterproof coating.
Through the screening of resins, flame retardants, de-foaming agents, thermal fillers and water repugnants, the coating can be quickly cured, insulation, thermal conductivity is excellent, flame retardant effect is good, water repugnant and anti-corrosion effect is long-lasting, mechanical performance is excellent, in line with the requirements of green coatings, to meet the requirements of use in the power industry.

the effect of ultraviolet aging on the basic properties of solvent-based expansion fire protection coatings


This paper studies the effects of ultraviolet aging on the phosphorus content, surface appearance, thermal stability and fire resistance of expansion fire protection coatings by using scanning electroscopes (SEMs), thermal heavy analyzers (TGs) and small refractable test furnaces, and studies the effects of paint on their above performance.
results show that:
with the ultraviolet aging test, the phosphorus content, thermal
stability, high temperature expansion into carbon and fire-resistant insulation performance of fire-resistant coatings have been significantly reduced;

Anti-fingerprint coating laboratory evaluation method research
Excerpt:
establish anti-fingerprint (Anti-fingerprint, AF) coating laboratory evaluation method is to develop mobile phone screen and mobile phone film AF coating basic coating.
paper proposes to study the relationship between the wetting of liquid on solid surface and solid surface energy by measuring the contact angle of water on the surface of the cell phone membrane to reflect the degree of wetting of the main component of water in the cell phone membrane surface by drawing a wetting envelope chart to show the degree of wetting of other components in the cell phone membrane surface.
On this basis, a contact angle based on the Young-Laplace equation fitting analysis of distilled water and diiodine methane on the surface of the cell phone membrane is designed, the surface energy parameters of the sample under test are obtained by owens-Wendt-Kaelble formula, the wetting envelope map is drawn and the envelope area area S is obtained by the area method to evaluate the surface wetting capacity of the liquid.
the contact angle value of the cell phone membrane in combination with water, and comprehensively analyze the anti-fingerprint effect of the cell phone membrane.
analysis of the anti-fingerprint effect of 3 kinds of mobile phone membrane through experiments, the results show that the designed evaluation method can reasonably reflect the anti-fingerprint effect of mobile phone membrane.
