Problems solved by technology

[0004] However, due to the lack of high temperature resistance of all-plastic polystyrene foam materials, its surface cannot be used in environments with high temperatures, generally below 100°C. If it is used for outdoor countertops, it will cause traces on the countertop due to focusing in the sun. , seriously affecting performance and appearance
In order to overcome this problem, CN108084625A is made of specially synthesized high-temperature-resistant materials, which can meet the needs of high-temperature resistance, but this product needs to use a large amount of high-temperature-resistant materials, resulting in high costs and difficulty in market promotion
At the same time, since all-plastic foam products are easy to burn, they must meet the requirements of flame retardancy in the process of downstream promotion. Although CN108084588A can meet the requirements of flame retardancy, the cost is too high. and lower cost products is an urgent need for the industry

Abstract

The invention relates to a high-temperature-resistant and flame-retardant co-extruded polystyrene foam material, which is divided into a surface layer and a core material, the core material is mainly prepared by carrying out extrusion granulation on general polystyrene (GPPS), high impact polystyrene (HIPS), an antioxidant, a foaming agent and the like as raw materials and finally carrying out co-extrusion molding with the surface layer, the surface layer is divided into a material A and a material B, the material A is obtained by compounding polysulfone, high impact polystyrene (HIPS) and a brominated epoxy resin modifier, and the material B is pure polysulfone resin. The bonding capacity of the surface layer and the core material of the obtained material is extremely high, and the stripping phenomenon is avoided; the finally obtained composite material has excellent high-temperature resistance, can be used in an environment of 150 DEG C without obvious change, and the surface layer has a relatively strong flame-retardant function.

Description

technical field [0001] The invention belongs to the technical field of polystyrene foamed materials, and in particular relates to a high-temperature-resistant, flame-retardant co-extruded polystyrene foamed material and a preparation method thereof. Background technique [0002] Imitation wood materials refer to building materials that can achieve imitation wood effects, aiming to replace real wood in order to save forest resources. Imitation wood materials can be divided into traditional imitation wood materials and advanced wood imitation materials: traditional imitation wood materials are mostly made of cement, and the imitation wood effect is formed by sealing or carving on its surface, but usually only imitates the external effect; The wood material is made by modern plastic processing technology, which can not only imitate the external decorative effect of real wood, but also simulate its performance, texture and even smell. Among the commonly used advanced wood-like ...
