Problems solved by technology

However, polyurethane is an organic polymer compound with poor fire resistance, which requires flame retardant modification; and polyurethane has low strength, which can reach 100% in many special occasions with high strength requirements (for example, as structural materials and supporting materials). The mechanical strength of the material needs to be improved by various means to achieve the purpose of reinforcement.
[0004]Therefore, there are endless wallboards prepared by using polyurethane as the core material to compound other boards. However, the existing polyurethane boards have poor thermal insulation and sound insulation performance, which leads to the use of The effect is average. Based on the existing phenomenon of serious noise pollution, it is a technical problem to be solved to provide a wall panel composed of composite panels with excellent thermal insulation and sound insulation effects.

Abstract

The invention discloses a shingle composed of composite boards, which belongs to the technical field of building material preparation and comprises a first panel, a first reinforcing layer, a polyurethane foam board, a second reinforcing layer and a second panel which are sequentially arranged from top to bottom. The polyurethane foam board is prepared by the following steps: preparing the following raw materials in parts by weight: 85-160 parts of polyether polyol, 75-180 parts of polyester polyol, 25-55 parts of diisocyanate, 8-10 parts of a temperature control material, 10-15 parts of a metal filler, 4-13 parts of a foaming agent and 8-18 parts of a chain extender; and step A12, a foam board frame mold is prepared, the metal filler is put into the mold and placed into a circular array shape, then the polyurethane premix is injected into the foam board frame mold, foaming forming is conducted, and the polyurethane foam board is obtained. The wall panel prepared by the invention has better heat preservation and sound insulation performance.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a wall panel composed of composite panels and a preparation method thereof. Background technique [0002] The thermal insulation performance of building exterior wall envelope directly affects the heating and energy consumption of buildings. As the earth's resources become increasingly scarce and the energy supply becomes more and more tense, people pay more and more attention to energy-saving architectural design. Various regions have also introduced corresponding promotion standards, and more and more people are beginning to devote themselves to architecture. Research and development of decorative thermal insulation technology for objects, especially building exterior walls. [0003] Polyurethane has excellent properties such as light weight, heat insulation, sound absorption and shock resistance, water resistance and corrosion resistance, and...
