Problems solved by technology

[0003] However, the existing acrylic sheet has single function, and during use, as the temperature rises, the acrylic sheet is prone to brittle fracture, and when the temperature exceeds a certain temperature, it will begin to soften, and the tensile state will show yield failure, which is difficult to apply to specific environments Medium; the heat insulation is not ideal, which limits the use of acrylic products to a certain extent; the present invention adds additives in the process of preparing acrylic boards, so that the acrylic boards can improve heat insulation, wear resistance and deformation resistance while maintaining their own characteristics sex

Abstract

According to the preparation method of the anti-deformation acrylic plate with the heat insulation and heat preservation functions, the acrylic plate base layer is prepared in a methyl methacrylate, butyl acrylate and diallyl adipate ternary polymerization mode, the strength of the acrylic plate is greatly improved, and the mechanical property is improved; wheat straw fibers and glass fibers are mixed and woven to prepare a fiber layer, and the fiber layer is used as an anti-deformation layer to enhance the anti-deformation capability of the acrylic plate; nano-silver-loaded nanofiber crystals are prepared from nanocrystalline cellulose, glucose and a silver ammonia solution, the antibacterial property of the acrylic plate is improved, and after graphene oxide quantum dots are added, the fiber entanglement capacity is improved, the internal stress of the acrylic plate is reduced, and the thermal insulation performance of the acrylic plate is improved; the hollow glass beads are uniformly dispersed in the foamed polyurethane to prepare the heat preservation layer, the hollow glass beads and the foamed polyurethane play a synergistic role in improving the heat resistance of the acrylic plate, and the heat insulation and heat preservation performance of the acrylic plate can be greatly improved by optimizing the component proportion.

Description

technical field [0001] The invention relates to the field of acrylic plates, in particular to a deformation-resistant acrylic plate with heat insulation function and a preparation method thereof. Background technique [0002] Acrylic is a kind of specially treated plexiglass. It is an important plastic polymer material. The acrylic sheet made of acrylic has the advantages of good light transmission, easy dyeing, easy processing, beautiful appearance, and long service life. It is widely used. In the construction industry; acrylic boards are mostly made of polyacrylate, which has high transparency and a light transmittance greater than 92%. Initially, acrylic boards were used in combination with aluminum-plastic board profiles, advanced screen printing, etc., and later in various fields of the national economy. Widely used, such as aerospace, navigation, advertising, sanitary ware, automobiles, machinery, instruments, daily necessities and other fields; [0003] However, the ...
