Embodiment 1

[0012] In this embodiment, the composition and weight ratio of the stone-plastic composite material are: 40% stone powder; 30% PVC resin; 30% plant powder. Among them, the stone powder is heavy calcium carbonate and light calcium carbonate stone powder. The vegetable flour is at least one of wheat straw flour, cotton stalk flour and mixed wood flour. PVC resin is also in powder form, and the fineness of the above three powders requires 300-800 mesh. Stone powder has high hardness and wear resistance, while PVC resin has good plasticity. The material composed of these two raw materials has the dual characteristics of stone and polymer materials. The composite board made of this material has the natural qualities of solid wood, It also has the characteristics of high hardness, wear resistance, high compressive strength, bending resistance, chemical corrosion resistance, and flame retardancy. Vegetable powder is used as a filler, which is lightweight and can increase the thickn...

Embodiment 2

[0021] Take materials according to the weight ratio of raw materials attached below, and use the manufacturing method described in the above-mentioned embodiment 1 to produce composite boards.

Embodiment 3

[0023] Take materials according to the weight ratio of raw materials attached below, and use the manufacturing method described in the above-mentioned embodiment 1 to produce composite boards.

Abstract

A composite stone-plastic material used to prepare composite plate with high strength and anticorrosion nature and no pollution of formaldehyde and radioactive material is proportionally prepared from stone powder chosen from light calcium carbonate stone powder and heavy one, PVC resin, and the powder of plant chosen from wheat straw, cotton stalk and wood.

Description

technical field [0001] The invention relates to a stone-plastic composite material and a composite board made of the material. Background technique [0002] At present, there are various building materials such as stone and wood, but the composite panels made of these materials are easy to emit formaldehyde and other harmful substances to the human body, causing environmental pollution, and are easy to deform, have a short service life, and easily cause the loss of limited resources! Contents of the invention [0003] In order to overcome the defects of the prior art, the technical problem to be solved by the present invention is to provide a pollution-free, high-quality stone-plastic composite material, and also provide a composite board made of this material. [0004] In order to achieve the above purpose, the technical solution adopted in the present invention is: a stone-plastic composite material, its components and weight ratio are: stone powder 30-70, PVC resin 25-5...
