A glass fiber environmental protection composite wallboard

Abstract

The invention belongs to the field of home building materials, and particularly relates to a novel glass fiber environment-friendly composite wall slab. The a novel glass fiber environment-friendly composite wall slab comprises an inner face layer, a middle layer and an outer face layer; the inner face layer is prepared from, by weight, 48-56 parts of continuous glass fiber, 6-10 parts of brominated epoxy resin, 18-24 parts of polycarbonate, and 15-20 parts of vinyl ester resin; the middle layer is prepared from, by weight, 60-66 parts of continuous glass fiber, 12-16 parts of epoxy resin, 18-24 parts of m-phthalic acid unsaturated polyester; the outer face layer is prepared from, by weight, 48-56 parts of continuous glass fiber, 6-10 parts of brominated epoxy resin, 18-24 parts of polycarbonate, and 15-20 parts of vinyl ester resin. The invention further discloses a preparation method thereof. The novel glass fiber environment-friendly composite wall slab has the advantages of effectively reducing harmful gas content in the wall slab, overcoming the shortcoming of using property in the current wooden wall slab from the source simultaneously, and reducing unnecessary troubles.

Description

technical field [0001] The invention belongs to the field of home building materials, and in particular relates to a glass fiber environment-friendly composite wallboard. Background technique [0002] With the increasing progress of social economy and technological level, people's requirements for home decoration are also constantly improving. Because the original cement wall lacks the functionality of three-dimensional decoration, or when it is necessary to make simple partitions in the interior space, it is often necessary to use certain decorative wall panels for work. There are many classifications of decorative wall panels. According to the material structure, they are: solid wood wall panels, reinforced composite wood wall panels, and the most popular glass wall panels. Solid wood wallboard is a decorative material formed after drying and processing of wood. It has the characteristics of natural pattern, comfortable foot feeling and safe use. It is an ideal material f...

AI Technical Summary

Problems solved by technology

The weakness of solid wood wallboards is that they have poor durability against humidity and sunlight. Humidity makes natural wood expand, but it shrinks when it dries out, resulting in cracks and even buckling, which brings a lot of inconvenience to people's lives.

Reinforced composite wood wallboard is a popular wall material in recent years. After the log is crushed, it is filled with glue, preservatives, and additives, and it is pressed by a hot press at high temperature and high pressure. Therefore, it breaks the physical structure of the log. It overcomes the weakness of poor stability of logs, but due to the addition of a large amount of adhesive, there are greater environmental hazards, and the content of formaldehyde and other harmful substances is relatively high, which affects people's physical and mental health

The glass wall panel is beautiful, but the wall surface is not realistic, and it is not conducive to protecting privacy

[0003] Therefore, the homogenization of products in the current home building materials market is serious, and it is difficult to have both the usability and environmental performance of the products. It is urgent to develop a new material to fill the gap in the market
