Problems solved by technology

[0004] Disadvantage 1: Resin-type artificial stone uses unsaturated polyester resin as the cementing agent. Since unsaturated polyester resin is liquid and other inorganic fillers are solid powder, it is not easy to mix evenly when mixing, and it is easy to generate heat during mixing, causing the resin to solidify in advance , resulting in uneven material of the finished sheet, easy to crack, warp and deform
[0005] Disadvantage 2: Resin-type artificial stone uses unsaturated polyester resin as the cementing agent, and the amount of resin used is too large, resulting in high cost of the finished board, not resistant to high temperature, and is a combustible material
These waste rocks are selected to produce some handicrafts, colored stone sand, and high-whiteness marble waste to produce some light and heavy calcium carbonate, and there is no effective and economically valuable way to use it.

Abstract

The invention provides a preparation method of a light weight panel. The preparation method of the light weight panel comprises the following steps of mixing the following raw materials in parts by weight: 10 to 20 parts of waste stone materials, 50 to 70 parts of microsphere particles, 10 to 20 parts of cement, and 6 to 8 parts of thermosetting phenolic resin powder so as to obtain a raw materialmixture; paving the raw material mixture, pre-pressing, hot-pressing, curing molding, cooling, and opening a mould to obtain a light weight panel blank body. The panel prepared by adopting the preparation method provided by the invention is dense and uniform in material, rich in color, uniform in color, higher strength and hardness, better in secondary processability without containing water, extra low in water absorption, and free of shrinkage and buckling deformation in a high-temperature high-humidity environment.

Description

technical field [0001] The invention belongs to the field of architectural decoration, and in particular relates to a preparation method of a lightweight board. Background technique [0002] Artificial stone usually refers to artificial stone solid surface material, artificial stone quartz stone, artificial stone granite and so on. Different types of artificial stone have different compositions. The main components are resin, aluminum powder, pigment and curing agent. Artificial stone is a "polymer material polymer", usually based on unsaturated resin and aluminum hydroxide filler, "polymer solid board" formed by stirring, pouring, heating, polymerization and other processes, generally known as : "Resin board artificial stone". [0003] Resin-type artificial stone is made of unsaturated polyester resin as a cement, mixed with aluminum hydroxide powder, natural marble crushed stone, quartz sand, calcite, stone powder or other inorganic fillers in a certain proportion, and ...
