Embodiment Construction

[0029] A method for producing a green and environment-friendly straw lightweight wall plate, characterized in that it is prepared according to the following steps:

[0030] Raw material preparation→surface treatment combined with physics and chemistry→uniform glue mixing→pavement→hot pressing in the mold→cutting to length→stacking protection and health preservation→inspection→product;

[0031] In the preparation of the raw materials, the raw materials are divided into two types, one is the surface layer raw material, and the other is the middle layer raw material, and the surface layer raw material is composed of wheat straw, rice straw, cotton stalk, peanut shell, bean stalk, rape stalk, sunflower Biomass fiber material composed of crushed one or more kinds of stalks, corn stalks or leaves; the raw material of the middle layer is composed of rice straw and wheat straw scraps with a moisture content of 10% to 15% to small pieces with a length of 1 mm to 30 mm. And mix accordin...

Abstract

The invention discloses an environmental-protection straw light wall board production method. The production method comprises the preparation steps of: preparation of raw materials-surface treatment through physical and chemical combination methods-uniform glue mixing-pavement-hot pressing molding in a mold-fixed length cutting-accumulation protection curing-inspection-products; in preparation of the raw materials, the raw materials are divided into two types: one is surface layer raw materials, and the other one is middle layer raw materials; in the surface treatment step, wax on the surfaces of straws are treated by adopting physical and chemical combination methods; chemical raw materials containing silicon-oxygen chemical bond structures similar to wax structures on the surfaces of the straws and being 0.01-0.5 mass% of the straws are added; then, adhesives capable of forming hydrogen bonds or chemical bonds with polyhydroxyl structures are added; and in uniform glue mixing, strengthening materials are added in glue mixing of the middle layer raw materials. No harmful gas is discharged from boards prepared by the method; and the boards are smooth, unified and beautiful in textures and high in strength, flame retardance, sound insulation and damp prevention.

Description

technical field [0001] The invention relates to a preparation method of a rice straw fiber plate, in particular to a production method of a green and environment-friendly straw light wall plate. It belongs to the technical field of building components and decoration. Background technique [0002] my country is a big country of grain production and also a big country of straw production. It can produce more than 100 million tons of straw every year, accounting for about 20%-30% of the total straw in the world. Among them, rice, wheat, soybean, corn, potato and other food crop straw About 580 million tons, accounting for 89% of the total straw; peanut, rapeseed, sesame, sunflower and other oil crop straw accounted for 8% of the total, cotton and sugarcane straw accounted for 3% of the total, increasing agricultural waste such as straw The research and development of new technologies for the comprehensive utilization of straw, the scientific and efficient use of straw resources,...
