Abstract

The invention relates to the field of building boards and in particular relates to a novel composite board and a preparation method thereof. The novel composite board comprises a bottom board and a panel layer which is stuck on the bottom board, wherein the bottom board comprises the following raw materials in parts by weight: 90-110 parts of PVC particles, 40-60 parts of calcium carbonate powder, 3-6 parts of a stabilizer, 1.0-1.4 parts of a foaming agent, 6-8 parts of a foaming regulator, 0.3-0.5 part of polyethylene wax, 0.3-0.4 part of internal lubricant, 0.2-0.4 part of oxidized polyethylene wax, 4-6 parts of chlorinated polyethylene, 0.5-1.5 parts of an internal lubricant additive and 9-11 parts of wood powder. The novel composite board has the good waterproof and damp-proof effects and solves the problem that common boards in the prior art are soaked by water so as to seriously deform. The novel composite board also has the recycling characteristic and solves the technical problem that a large amount of wood needs to be consumed in wooded boards in the prior art.

Description

Technical field [0001] The present invention relates to the field of building boards, in particular to a novel composite board and a preparation method thereof. Background technique [0002] Board is a kind of engineering construction material widely used in construction and interior decoration. In this field, the selection of boards is mainly based on natural wood materials. The existing wooden boards currently on the market consist of the following types: (1) solid wood logs; (2) multilayer solid wood; (3) reinforced composite wood. The above-mentioned boards are all made of wood as the main raw material. Therefore, they have the following shortcomings: 1) It needs to consume a lot of forest resources, which directly causes damage to the ecological environment; 2) It is not waterproof (for example, it is After blister, it will be severely deformed, which will affect its use), flammable, and very easy to expand and contract with heat (determined by the characteristics of the wo...
