Silicon-aluminum composite imitation wood molding material and its technology

Abstract

The invention relates to a silicon-aluminum composite wood-simulating moulding material and a process thereof. The material is prepared from the following raw materials by weight percent: 50-75% of gangue fibers, 15-35% of a high molecular blending fireproof modified material, 8-25% of a silicon-aluminum clinker and 0.1-10% of stearic acid through mixing, wherein the high molecular blending fireproof modified material consists of 40-60wt% of a high molecular blending modified material and 40-60wt% of a chemical assistant. The fireproof performance of a wall body prepared by the silicon-aluminum composite material reaches the level A, the fire endurance is longer than 2 hours, and the material has the advantages of light weight and easiness in moulding, cyclic utilization, arbitrary assembly and long service life, and no crack and warp are generated. A colorant, a membrane or a composite layer are added to form various colorful products, and meanwhile, the material is worm damage resistant and aging resistant.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a silicon-aluminum composite imitation wood molding material and a process thereof. Background technique [0002] In recent years, due to the reduction of timber resources in the world, China's timber resources have decreased faster. On the other hand, with the improvement of people's living standards, human beings have higher and higher requirements for the quantity and quality of timber utilization, and my country can provide Timber resources are very limited, therefore, the contradiction between supply and demand of timber resources is becoming increasingly prominent. At present, there are three main ways to solve the contradiction between timber supply and demand: (1) increase timber imports; (2) vigorously develop artificial fast-growing forests; (3) look for alternative materials. First of all, increase the import of timber. In recent years, the number of timb...

Problems solved by technology

At present, there are many researches and developments of wood-like molding materials in China, but the preparation process of these wood-like materials uses wood raw materials to varying degrees. The production cost of these materials is high, and these products are easy to absorb moisture, and the waterproof performance needs to be improved. The preparation process is relatively complicated. Moreover, these materials have high density, low hardness, easy deformation, poor fire resistance, cannot be recycled, poor impact resistance and poor thermal stability, which restrict the application of imitation wood molding materials
