Problems solved by technology

[0008] For polypropylene, the effective method of flame retardant is mainly to add flame retardant in the melt spinning process to make the fiber have lasting flame retardancy. Halogen / antimony series is currently a mature and effective flame retardant, mainly through the gas phase flame retardant mechanism-inhibit The free radical chain reaction of gas phase combustion achieves the purpose of flame retardancy, and it has a good flame retardancy effect at a low concentration, but there are environmental problems that will produce a large amount of corrosive hydrogen halide gas and other toxic halides during the combustion process restricted by the international community

Abstract

The invention discloses a formaldehyde-free lightweight composite board for decoration and a preparation method thereof. The formaldehyde-free lightweight composite board for decoration is composed of a composite board and a surface decoration. The invention adopts environment-friendly glass fiber and polypropylene fiber to manufacture the decoration material. The material is non-toxic, does not produce chemical pollution such as formaldehyde, has excellent flame retardancy, low energy loss and outstanding environmental protection performance. The board of the invention is made of fibers cross-laid and needle-punched into felt. It has excellent comprehensive mechanical properties and can realize the lightweight of decoration materials. The processing technology of the invention is simple and unique, and can improve work efficiency. The products produced have Light weight, smooth surface, low moisture content, high and low temperature resistance, impact resistance, wrinkle resistance, strong toughness, good sound absorption and heat insulation, no deformation, no discoloration, etc., and no sharp-angled section after crushing, which is relatively safe Reliable; can be widely used in decoration.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a formaldehyde-free lightweight composite board for decoration and a preparation method thereof. Background technique [0002] Indoor pollution in our country is relatively serious. First of all, decoration materials are one of the most important sources of formaldehyde pollution. The change of decoration materials is one of the products of the rapid development of modern society. [0003] The advancement of science and technology has not only greatly improved our lives, but also brought troubles and disasters that did not exist before. When manufacturing decoration materials, many businesses use a large amount of some chemicals for the sake of profit. The use of these chemicals in a small amount within the specified range will not cause major problems, but if these chemicals are used in large doses, not only The manufacture of decoration materials has becom...
