Magnesium-calcium fire-proof plant fiber board and method of manufacturing the same

Abstract

A magnesium-calcium fireproof plant fiberboard and a preparation method thereof, which consist of 1-2.4 parts of inorganic gelling material, 1.5-2.5 parts of plant fiber, 0.025-0.03 part of sodium methyl silicate and 1.4-1.8 parts of stirring solution. The semi-dry material is hot-pressed and formed, and the fiberboard of the present invention is produced through raw material preparation, mixing and stirring, paving and pre-pressing, hot-pressing and shaping, and cutting to length. Its products do not contain formaldehyde, have the characteristics of environmental protection, non-toxic, harmless, no cracks, light heat preservation, shrinkage, small expansion coefficient; The disadvantages of anti-halogenation of magnesium products are that they have the characteristics of inorganic materials and are compatible with the characteristics of wood. The texture is fine and dense, the natural texture is strong, and it is easy to nail planing, cutting, fixing and bonding. Moreover, the production process is simple, the molding speed is fast, no need for curing and drying, high flexural strength, uniform density, and no deformation. Suitable for building materials, packaging, transportation and decoration industries.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a magnesium-calcium plant fiberboard with fireproof performance and a preparation method thereof, which is mixed with organic materials and inorganic materials. Background technique [0002] With the rapid development of my country's socialist construction and the continuous improvement of people's living standards, the demand for timber has increased significantly, so the number of logging logs is increasing, making the supply of timber in my country, which has a small forest coverage area, also increasing. become increasingly tense. In order to maintain ecological balance and meet the needs of the four modernizations and people's growing needs, while increasing the amount of imported wood, the country will vigorously develop new environmentally friendly building materials, save resources, and produce waste-based wood products as an important measure and Long-term p...

Problems solved by technology

The ubiquitous problem is that most of the raw materials contain chemical additives such as UF or PF glue as a binder, and the harmful substances in them not only pollute the environment but also endanger human health; most of the components in the raw materials are organic matter, waterproof, fireproof, Poor anti-corrosion and moth-proof performance

The process is slightly complicated, and requires two high-temperature treatments, which increases the cost, especially the fiberboard produced still has the defect of anti-halogen
