Problems solved by technology

[0003] At present, the paint with diffuse reflection function is limited to small sites (such as: laboratories and manual spray booths) to make small parts (such as: A3 advertising boards, car lampshades, etc.), and cannot be applied to mass industrial production and large-scale building decorative panels. At the same time, non-painted products with diffuse reflection function have obvious defects in high temperature resistance, color change resistance, chemical corrosion resistance, etc., especially when used in indoor places, safety hazard is the biggest deficiency

Embodiment 1

[0026] Embodiment 1 paint and preparation method thereof

[0027] 1. Paint components (by weight):

[0028] 42 parts of saturated polyester resin, 7 parts of permethyletherified amino resin, 32 parts of titanium dioxide, 0.6 parts of leveling agent, 0.6 parts of defoamer, 0.6 parts of acid catalyst, 5 parts of fumed silica, and 13 parts of solvent.

[0029] 2, the preparation method of above-mentioned paint is as follows (also can refer to figure 1 ):

[0030] (1) Preparation of color paste: Mix 20 parts by weight of resin and 6 parts by weight of 150# solvent at room temperature, stir evenly under no-pressure conditions, add pigment at a uniform speed while stirring, and continue stirring after the addition is completed. Between 1-2 hours, the fineness of the mixture reaches within 20 microns;

[0031] (2) Addition of acid catalyst: Add the remaining 29 parts by weight of resin and 7 parts by weight of 150# solvent in the color paste prepared by step (1), and then add 0.6 ...

Abstract

The invention discloses a paint and its preparation method and application. The paint comprises the following components in parts by weight: 45-53 parts of resin, 30-35 parts of pigment, 1-3 parts of auxiliary agent, and 4-6 parts of matte powder , and 10-15 parts of solvent, wherein, said auxiliary agent comprises leveling agent, defoamer and acid catalyst, and the preparation method of this paint comprises (1) making of color paste and (2) adding of acid catalyst, to obtain The paint can provide a coating with a high diffuse reflection function for the interior decorative board, improve the utilization rate of indoor natural light, and reduce indoor light and heat loss while increasing the decorative effect.

Description

technical field [0001] The invention relates to the field of paint, in particular to a paint and its preparation method and application. Background technique [0002] Paint is a mixture of organic or inorganic materials used to decorate and protect objects. In terms of decorative functions, it can play the role of anti-corrosion, waterproof, oil-proof, chemical resistance, light resistance, temperature resistance, etc. Because the objects are exposed to the atmosphere, they are eroded by oxygen, moisture, etc., causing metal corrosion, wood decay, For damage phenomena such as cement weathering, paint on the surface of the object to form a protective film can prevent or delay the occurrence and development of these damage phenomena and prolong the service life of various materials. In terms of decorative functions: objects of different materials can be coated with paint to obtain colorful and colorful appearances, which can beautify the living environment of human beings and...
