Problems solved by technology

Due to the high brightness of the product, before the product is cured after construction, it will attract dragonflies, mosquitoes, etc. to fall to the surface, resulting in obvious defects in the leveled site, which will affect the overall effect of the site; some plastic products used indoors do not need to be reused. For the construction surface, if the reflection is too strong under the indoor light, it will cause greater damage to the eyes of the user
At present, the construction of water-based polyurethane materials has a good matte effect, but the thickness of the product should not be too thick in one construction, and the water volatilization is slow at low temperature, the construction efficiency is low, and the applicability is limited; the matte effect can be achieved by adding matting powder during the construction process , but too much added amount will pollute the site, and there will be uneven dispersion, which will affect the strength and durability of the product; adding matting powder directly to the conventional products in the factory can avoid the pollution and uneven dispersion caused by on-site addition, but also due to A large amount of matting powder needs to be added, which will affect the strength and durability of the product. Some manufacturers' products also have the problem of inconsistent matting properties of the upper and lower layers after long-term storage
[0004] In addition to the problem that plastic products are not matte, the product also has a problem of bright surface, which needs to be polished before construction, which affects the construction progress

Abstract

The invention belongs to the field of polyurethane synthesis, and particularly relates to a matte plastic material and a preparation method thereof. The matte plastic material is prepared from polyether polyol, isocyanate, filler, pigment, a catalyst, an antioxidant, an ultraviolet light absorber, a wetting dispersant, a defoaming agent, matte powder and a latent curing agent, and has the advantages of excellent matte property, no need of polishing of a construction surface layer, high strength, moderate viscosity, excellent operation time, durability, environmental protection and the like. The preparation method is scientific, reasonable, simple, easy to implement and suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of polyurethane synthesis, and in particular relates to a matte plastic material and a preparation method thereof. Background technique [0002] Polyurethane plastic venues have been favored by everyone since their birth for their good flatness, high compressive strength, moderate hardness and elasticity, bright and beautiful colors, stable physical properties, and excellent weather resistance. On the one hand, we see the advantages of plastic materials, but there are also certain disadvantages in the product: it is not matte, and it is easy to get mosquitoes before it is cured; it is troublesome to deal with; the surface layer needs to be polished before construction. [0003] After normal curing, the polyurethane material is in a mirror film leveling state. When light reaches the surface of the material, part of the incident light is absorbed and part is reflected, and the reflected part makes the material appear gl...
