Abstract

The invention discloses a lightweight composite wall board and a production method thereof. The lightweight composite wall board is characterized by being prepared from the following raw materials in parts by weight: 140-150 parts of SG-3 polyvinyl chloride, 15-20 parts of nylon PA66, 30-35 parts of straw powder, 27-30 parts of quartz sand, 3-4 parts of ethylene foamed particles, 4-5 parts of glass fiber, 3-4 parts of sodium metasilicate, 12-16 parts of modified loess powder, 2-3 parts of used oil, 2-3 parts of sodium tripolyphosphate, 1-2 parts of an ortho-hydroxybenzoic acid, and 3-4 parts of dichlorodifluoromethane. The lightweight composite wall board disclosed by the invention has a high mechanical strength, the tensile strength is at least 0.4 MPA, and the pressure-shear bond strength is at least 0.1 MPA; the lightweight composite wall board is good in sound insulation and weather resistance, strong in wind / negative pressure resistance, capable of being hung by nails, impact-resistant, fireproof, good in bearing capacity, and long in service life.

Description

technical field [0001] The invention relates to a wall board, more specifically, a lightweight composite wall board and a preparation method thereof. Background technique [0002] In house construction, especially in alpine regions, a large amount of heat in the house is dissipated through the roof and walls. Therefore, it is necessary to pave insulation boards on the roof and outer walls to play the role of thermal insulation and energy saving. Existing extruded insulation boards have the disadvantages of low strength, low compression resistance, low density, weak aging resistance, and high cost. New products need to be launched to participate in the competition. Contents of the invention [0003] The object of the present invention is to provide a lightweight composite wall board and a preparation method thereof. [0004] The technical scheme adopted in the present invention is: [0005] A lightweight composite wall board, characterized in that it is made of the follo...
