Method for producing building material board

Abstract

This invention relates to a method for producing novel building material. It is characterized by; the raw materials magnesium oxide, anhydrous sulfuric acid, straw, inorganic adhesives, pearlite, silica flour, asbestos fiber, copper naphthenate, silica white and glass cloth are proportioned and then are proceeded steps: mixing, agitating, moulding, demoulding, drying to obtain the inventive product. This invention has advantages of: low cost, simple process, water-proof, sound-insulation.

Description

technical field [0001] The invention relates to a production method of a building material board. Background technique [0002] Existing building material panels, some are waterproof, some are heat-insulating, and some are sound-insulating, but few have all kinds of properties, and most of them contain a large amount of magnesium chloride, which leads to a large content of harmful substance monochlorine in the product, and is easy to cause Product dehumidification. Contents of the invention [0003] The object of the present invention is to provide a production method of a light-weight building material board which is waterproof, heat-insulating and sound-insulating. [0004] The object of the present invention is achieved like this: be batching by following weight ratio: straw 30-40%, magnesium oxide 20-25%, magnesium chloride 10-15%, anhydrous sulfuric acid 5-10%, perlite 5-10% , 5-10% of quartz powder, 5-10% of asbestos wool, 3-5% of copper naphthenate, 3-5% of white ...
