Ceramic composite timber precursor liquid and its preparation method

Abstract

Ceramic composite timber precursor liquid and its preparation method, wherein the precursor liquid comprises inorganic composition, organic composition, functional enhancement component and process enhancement component, the inorganic composition is silicasol or soluble silicate, the organic composition is water-based polyurethane emulsion or water-based acrylic acid emulsion, the weight ratio of the organic composition with the inorganic composition is 0.25-0.7:1, the weight ratio of the methyl sodium metasilicate as the enhancement component with the inorganic composition is 4-7:100, the process enhancement component includes coupling agent KH-560 and sodium alkyl benzene sulphonate as penetrating agent, the weight ratio of the coupling agent and the organic composition is 1.2-2:100, the weight ratio of sodium alkyl benzene sulphonate and the inorganic composition is 1.6-2:100. And the preparation process comprises the steps of weighing according to the weight ratio, and mixing homogeneously.

Description

technical field [0001] The invention discloses a ceramic composite wood precursor and a preparation method thereof. The ceramic composite wood precursor can be used to prepare reinforced composite wood, and belongs to the technical field of preparation of composite reinforced wood in building materials. Background technique [0002] With the progress and development of society, the human demand for wood is also increasing. However, with the shrinking of high-quality forests and the strengthening of natural environment protection in the world, the supply of high-quality wood is seriously insufficient. Although the artificial fast-growing forest timber is huge in quantity, there is a big gap in its various performances compared with natural high-quality timber, so that it can only be applied in non-critical parts of local areas, and cannot make up for the reduction in the supply of natural high-quality timber. In this case, how to modify the artificial fast-growing forest wood...

Problems solved by technology

However, the simple use of organic precursor liquid also has disadvantages. Its raw material cost is high, and the control process adopted during impregnation treatment is complicated, which makes the price of the produced wood-plastic composite material remain high, hindering its wide application; The impregnation method is used to fill the wood with simple inorganic materials, and some results have been achieved. The hardness of the prepared ce...
