Problems solved by technology

However, most of these imitation paints need to be sprayed many times, which have poor adhesion, weather resistance and flame retardancy. Over time, the paint is easy to fall off and crack, which greatly affects the appearance and loses the value of "imitation wood".

preparation example

[0027] Silicone-modified polyimide powder was prepared according to the following steps (1)-(4), wherein the raw materials, proportions and reaction conditions are shown in Table 1.

[0028] (1) Dissolving the dianhydride in a solvent to prepare a dianhydride solution with a mass concentration of 5-10%, and adding dropwise a diamine solution of the same solvent with a mass concentration of 5-10% in the solution, wherein the dianhydride and the dianhydride The molar ratio of the amine is 1.0-1.1:1 to obtain a polyamic acid solution;

[0029] (2) After the reaction finishes, add 2-5% aminoalkoxysilane of polyamic acid solution quality, make it fully react;

[0030] (3) preparing the product of step (2) into an aminoalkoxy-modified polyimide film with a thickness of 5-80 μm by solution casting, salivation, or solution extrusion;

[0031] (4) Shear and pulverize the film to 400-500 mesh powder.

[0032] Table 1

[0033]

Embodiment 1

[0035] Dissolve 100kg of bisphenol A type epoxy resin (E-03 type) and 150kg of silicone modified polyimide powder Z-1 in 400kg of solvent (dimethyl carbonate: ethanol volume ratio 1:1), in 200 Mix at ℃ for 5 hours;

[0036]Each component (sodium pyrophosphate 64kg, trisodium phosphate 64kg, organobentonite 96kg, diatomite 64kg, hibiscus red colored sand 32kg, blue gray colored sand 18kg, snowflake white colored sand 12kg) as auxiliary agents was put all at 70°C The auxiliary agent is mixed and added to the above solvent mixture to obtain the imitation wood composite paint of the present invention.

Embodiment 2

[0038] Dissolve 150kg of bisphenol F epoxy resin (EP-4901E) and 150kg of silicone modified polyimide powder Z-2 in 600kg of solvent (ethanol: n-butanol volume ratio 1:2), at 200°C Mix for 5 hours;

Abstract

The invention relates to a wood-like composite paint and a preparation method thereof. The wood-like composite paint of the invention comprises, by weight, 10-15% of epoxy resin, 10-15% of organosilicon modified polyimide powder and 40-60% of a solvent, with the balance being an auxiliary agent. The wood-like composite paint can be directly sprayed on a cement wall or steel plate at a time, and has good wood-like effect, no cracking, no paint shedding, high weather resistance, high insulation performance and high flame retardancy.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to a wood-like composite paint and a preparation method thereof. Background technique [0002] In traditional industries, wood is the main material used for home panels and construction projects. However, the over-exploitation of forest resources has caused the deterioration of the ecological environment and soil erosion. Therefore, in order to save forest resources and avoid deforestation, "imitation wood" technology has begun to flourish. develop. The most rapid development is wood-like boards, such as polyurethane, polyethylene, etc. combined with micro-foaming, injection molding or extrusion molding processes to form syntactic foams. They have high rigidity and mechanical strength. From the perspective of strength, their It is perfect to replace wood, but this kind of material itself has a very low ignition point and is extremely flammable, which poses a safety hazard.
