Stone-plastic composite board and production method thereof

Abstract

The invention discloses a stone-plastic composite board, and belongs to the field of building decoration. According to the technical scheme, the stone-plastic composite board is characterized by comprising a stone-plastic base layer and a plastic film protection layer wrapping the outer side of the stone-plastic base layer, and the plastic film protection layer is a PVC film protection layer or aPE film protection layer. The invention further discloses a production process of the stone-plastic composite board. The process includes the following steps of S1, mixing raw materials, wherein 100-200 parts by weight of PVC, and 200-600 parts by weight of stone powder or 200-500 parts by weight of wood powder are mixed; S2, conducting extrusion molding on the mixed raw materials in the step S1,and then conducting cool-forming; S3, conducting whole-size cutting on a semi-finished product cool-formed in the step S2 according to the size to form the stone-plastic base layer; S4, conducting panel attaching operation on the stone-plastic base layer in the step S3 through a PVC film to form the stone-plastic composite board. The stone-plastic composite board can replace an artificial stone and quartz stone board, no secondary processing is needed, and no secondary pollution damaging the environment and human bodies can be generated.

Description

Technical field [0001] The invention relates to the field of architectural decoration, in particular to a stone-plastic composite board and a production method thereof. Background technique [0002] At present, artificial stone or quartz slabs are used in home furnishings such as cabinets, bathroom, window sills, TV background walls and door stone; at the same time, artificial stone or quartz slabs are also used in various high-end office buildings, hotels, squares and large curtain walls. However, in the process of using artificial stone or quartz slab, it is usually necessary to perform secondary processing-cutting of artificial stone or quartz slab, and dust pollution will be generated during the cutting process, causing secondary pollution to the environment and harm to the human body. . Summary of the invention [0003] In view of the shortcomings of the prior art, one of the objectives of the present invention is to provide a stone-plastic composite board, which has the adv...
