Stone plastic board and processing method thereof

Abstract

The invention relates to the technical field of building materials, and specifically relates to a stone plastic board, which comprises a substrate layer, a color film layer, and a UV layer from bottomto top. The substrate layer is prepared from following raw materials in percentage by weight: 52.5 to 72.5% of calcium powder, 20 to 30% of PVC powder, 2.5 to 8.5% of a lubricant, and 5 to 9% of a reinforcing agent. The color film layer is prepared from PVC. The stone plastic board is nontoxic and environmentally friendly, and is harmless to the environment and humans. The substrate layer mainlymade of PVC powder and the color film layer made of PVC can be better combined.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a stone-plastic board and a processing method. Background technique [0002] In the field of building panels, the commonly used bottom panel materials can be divided into the following types: wooden panels, natural stone, wood-plastic materials, ceramic tiles, etc., but in practical applications, it is found that the above-mentioned materials have their own defects in use, such as: wood The panels have poor moth resistance, cannot be fireproof and moisture-proof, and have poor thermal conductivity; ceramic tiles are fragile and cold in texture; natural stone is difficult to process, and in order to combine with the foundation, cement needs to be used as a binder, and the texture is cold due to high thermal conductivity; Wood-plastic materials contain organic binders and other chemical substances, which are prone to produce small molecule harmful gases when used in indo...

[0003] In the prior art, it is proposed to mix marble powder and plastic to prepare artificial synthetic stone, also known as stone-plastic plate, but from the perspective of saving materials and reducing weight, some stone-plastic plates are in the plate The groove is set at the bottom of the board, but in the long-term use process, it will be found that the setting of the groove is easy to cause uneven stress on the board structure and deformation
