High Pressure Laminate and Production Method Thereof

Abstract

The present invention discloses a decorative High Pressure Laminate (HPL) and production method thereof, which relates to the technical field of building decoration materials. The raw materials of HPL may include magnesium oxide, magnesium sulfate, water, fiber, perlite, glass fabric, quartz powder and modifier, wherein the percentage by weight of magnesium oxide is 35% to 40%, the percentage by weight of magnesium sulfate is 20% to 25%, the percentage by weight of water is 20% to 25%, the percentage by weight of fibers is 5% to 10%, the percentage by weight of perlites is 0.5% to 0.9%, the percentage by weight of glass fabrics is 1% to 2%, the percentage by weight of quartz powder is 8% to 12%, and the percentage by weight of modifier is 0.1% to 0.5%. According to the technical solutions, the disclosed HPL may include magnesium oxide, magnesium sulfate, water, fiber, perlite, glass fabric, quartz powder and modifier according to appropriate proportions, and the product produced has low hygroscopicity, no helogenation, no rust, no discoloration, and has high anti-demolition force; moreover, magnesium sulfate has no corrosion on the glass fabric, thus, the laminate has a long life.
