Problems solved by technology

However, in the existing exterior wall materials, especially the raw materials for the production of polyurethane elastomer exterior wall materials, the reinforcement and modification of anti-cracking isoprene rubber pulp are usually compounded with fiber materials, and these fiber materials are generally polypropylene fibers, asbestos, etc. etc., due to the price and environmental protection problems of these two fiber materials, there is a certain development trend in the preparation of exterior wall materials by using cheap and environmentally friendly anti-cracking isoprene rubber pulp

Abstract

The invention relates to a building wall material, and concretely relates to a crack, oil and high temperature resistant polymer modified exterior wall material and a production technology thereof. The technology comprises the following steps: mixing modified rubber powder, polyurethane elastomer, a tetrafluoroethene-hexafluoropropene copolymer, isoprene rubber, re-dispersible latex powder, quicklime, cellulose ether and an air entraining agent through a mixer, kneading through a kneader, placing the obtained mixture in a die, and compacting through a flat vulcanizer to obtain an exterior wall panel. The above exterior wall material product made in the invention reduces the use amount of wood fibers, the production cost and the sheet unit weight, and has improved compressive strength, flexural strength, bending toughness, oil resistance and high temperature resistance. The polyurethane elastomer added in the invention effectively improves the mechanical properties of a polypropylene cable material; fluorubber added in the invention has high temperature and oil resistance; and other fillers added in the invention can enhance other physical properties and the processability of the cable.

Description

Technical field [0001] The invention relates to a building wall material, in particular to a composite exterior wall building material using polymer modified anti-cracking isoprene rubber slurry as a raw material. Background technique [0002] With the vigorous development of the construction industry and the modernization of buildings, exterior wall materials used in construction projects have also been widely used and valued. The isoprene rubber grout used in traditional exterior wall materials can cause wall cavities, cracks and fall off, which will not only affect the use of wall materials, but also affect the quality of the project. In order to enhance the comprehensive performance of exterior wall materials, the modified anti-cracking isoprene rubber slurry has attracted wide attention. However, in the existing external wall materials, especially the raw materials for the production of polyurethane elastomer external wall materials, the reinforcement and modification of an...
