An environmentally friendly flame retardant straw board

Abstract

The invention discloses an environment-friendly flame-retardant straw board. The straw board is prepared from the following raw materials in parts by weight: 50 to 100 parts of straw particles, 10 to 200 parts of flame retardant agent, and 1 to 50 parts of binding agent, wherein the flame retardant agent is prepared from the following raw materials: magnesium oxide, magnesium chloride, magnesium sulfate, nano stibium oxide and ultra-fine micro-silica powder; the binding agent is inorganic binding agent and is prepared from the following raw materials: aluminum sol, water glass, polyvinyl alcohol and deionized water. According to the environment-friendly flame-retardant straw board, by combining with the inorganic flame retardant agent and the inorganic binding agent with excellent performance, straw is used as a main raw material, so that the obtained straw board is flame-retardant without being carbonized and deformed at a high temperature of 1200 DEG C or more, and the production of harmful fume and gas is avoided; moreover, heat conduction on the straw board is avoided under a high temperature condition, and the straw board is not swelled once encountering the water, and the comprehensive performance is very excellent.

Description

Technical field [0001] The invention belongs to the technical field of wood-based panels, and specifically relates to an environmentally friendly flame-retardant straw board manufactured by using straw as the main raw material. Background technique [0002] With the development of social economy, people’s life quality requirements are getting higher and higher. At present, multi-layer wood panels, blockboards and medium-density boards are often used in building decoration, furniture production and other industries. Among them, these three types of decorative panels all have the same shortcomings: they are not fireproof, have a large amount of harmful substances, seriously endanger the health of users, and need to consume a lot of wood. [0003] Although there are all kinds of fireproof boards (such as gypsum board, cement board, magnesium oxide board, calcium silicate board, etc.) on the market, the finished products are all one kind of material. In other words, the finished produc...

Problems solved by technology

[0002] With the development of social economy, people's life quality requirements are getting higher and higher. At present, multi-layer wooden boards, blockboards and medium density boards are often used in architectural decoration, furniture production and other industries. Among them, these three kinds of decorative panels have common disadvantages: they are not fireproof, contain a lot of harmful substances, seriously endanger the health of users, and consume a lot of wood.

To sum up, from a purely technical point of view, the core technical problem of crop straw-based panels at home and abroad is firstly the problem of gluing. Due to the application of MDI resin, the technology of modern straw-based panels has developed in stages, but Even so, compared with wood-based panels, there is still a considerable gap; especially in the collection and preparation of raw materials, production equipment, and product costs, whether it can be widely used and promoted, it is still necessary to find a way that suits China's national conditions. development path
