Abstract

The invention relates to the field of chemical engineering, and particularly discloses a polyurethane adhesive for glass magnesium compounding and a preparation method of the polyurethane adhesive. The polyurethane adhesive for glass magnesium compounding comprises the following raw materials: vegetable oil polyol, polycarbonate polyol or polycaprolactone polyol, polyether polyol, a chain extender, a coupling agent, an anti-hydrolysis agent, a fluorine-containing auxiliary agent, carbon fiber powder, a rheological auxiliary agent, a filler and the like. The prepared polyurethane adhesive for glass magnesium compounding has excellent water resistance and heat resistance, belongs to a boiling-resistant two-component solvent-free polyurethane adhesive for glass magnesium boards, can be used for glass magnesium compounding through reasonable use of multiple raw materials, and has good hydrolysis resistance and alkali resistance; and the hardness, the adhesive property, the impermeability,the heat resistance and the water resistance are improved, and the problem that the water resistance and the heat resistance are not high when an existing polyurethane adhesive is used for preparing aglass magnesium board-based composite floor is solved. The preparation method provided by the invention is simple in condition and low in cost.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a polyurethane adhesive for glass-magnesium composite and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, consumers have higher and higher requirements for the field of home decoration, especially the requirements for fire and flame retardant performance. In addition, for composite flooring manufacturers, traditional PVC (polyvinyl chloride) flooring, WPC (wood-plastic composite) flooring, and SPC flooring (stone plastic lock composite) generally have poor dimensional stability of finished products, and are prone to heat expansion and contraction. Deformation, especially the relatively expensive cost of materials and other issues. The glass magnesium board-based composite floor is a material obtained by combining glass magnesium board with other boards (for example, wood board, veneer, etc.), which not only has the a...
