Abstract

The invention discloses glue liquor for an environment-friendly light laminated board, the laminated board and a preparation method of the glue liquor. The glue liquor for the environment-friendly light laminated board is made of raw materials which include, by mass, 450-500 parts of resin, 8-12 parts of curing agents, 0.2-0.3 part of a curing catalyst, 100-120 parts of solvents and inorganic filler which takes 5-60% of the total mass of the glue liquor for the environment-friendly light laminated board, wherein the average real density of the inorganic filler is 0.12-1.5g/cm3. According to the glue liquor, the light inorganic filler is added to the glue liquor, the density of the laminate board can be greatly reduced, meanwhile the laminated board has high heat insulation performance, high heat-resistant performance, high size stability and low thermal expansion coefficient, and product performance is greatly improved.

Description

technical field [0001] The invention relates to the field of laminated boards, in particular to an environment-friendly glue for lightweight laminated boards, a laminated board and a preparation method thereof. Background technique [0002] With the development of printed circuit boards, especially the advancement of packaging technology, packaging components are developing in the direction of lightness, thinness, and miniaturization. It is bound to require copper clad laminates (also known as copper clad laminates) to have better performance, such as low Density, high heat resistance, high dimensional stability and low coefficient of thermal expansion. At present, most copper clad laminates on the market use the method of adding inorganic fillers to the glue to improve the local performance of copper clad laminates, such as aluminum hydroxide, magnesium hydroxide and other inorganic fillers. It starts to decompose and release moisture, which will easily lead to deformation...
