Fireproof flame-retardant straw brick and preparation method thereof

Abstract

The invention discloses a fireproof flame-retardant straw brick and a preparation method thereof. The fireproof flame-retardant straw brick comprises the following components in parts by weight: 55-80parts of straw, 20-40 parts of perlite, 0.5-1 part of borax, 0.5-1 part of bonic acid, 2-4 parts of ammonium polyphosphate, 3-6 parts of an aqueous polyamide resin, 5-10 parts of red soil powder, 1-5parts of talcum powder, 5-10 parts of waste foamed plastic, 20-40 parts of cement, 10-15 parts of building wastes, 4-8 parts of an epoxy resin, 1-5 parts of aluminum powder, 3-6 parts of a curing agent and 7-10 parts of a waterproof agent. The preparation method comprises the following steps: (1) crushing the straw to 0.1-0.3mm; (2) mixing the raw materials with water according to a certain ratioso as to obtain slurry; (3) pressing and molding the slurry; (4) naturally drying in an environment of 20-35 DEG C, thereby obtaining a finished product brick. The fireproof flame-retardant straw brick disclosed by the invention has efficient fireproof and flame retardant properties and pressure resistance.

Description

technical field

[0001] The invention belongs to the field of building materials, and in particular relates to a fire-proof and flame-retardant straw brick and a preparation method thereof. Background technique

[0002] With the rapid development of my country's construction industry, the demand for building materials is increasing, and people are actively developing green and environmentally friendly building materials, so straw building materials have entered people's sight. Straw is rich in nitrogen, phosphorus, calcium and organic matter, etc. It is a renewable resource with multiple uses. The building materials produced with straw as raw materials have the characteristics of light weight and heat preservation. At the same time, hollow bricks have become the first recommended by the national construction department. Because the hollow brick has the advantages of light weight, heat preservation, less raw material consumption, and no pollution, the straw hollow brick prepar...
