example 1

[0008] Take 80kg of 320-800mesh fly ash, 80kg of wollastonite, 28kg of polyvinyl chloride resin, carbon black, zinc borate, 4kg of compound modification additives, etc., and dry them with a high-speed shear mixer at 110-150°C for 1-1.5 hours for fully coupled cross-linking. Put the uniformly mixed material into a high-temperature extrusion granulator for granulation. The particle size is 3-5mm, and the particle length is 0.5-1.5cm. Extrude the pellets through a single-screw or conical twin-screw extruder equipped with a special mold at 120-240°C, then press out three-dimensional patterns on the surface, and cool with water to form a calcium-wood composite board substrate. The board-shaped substrate is based on Use occasions and size requirements Use an infrared control cutting machine to cut to the required size, and pack it into the warehouse after passing the inspection.

Abstract

The invention discloses a novel calcium-wood composite material, and relates to a composite board prepared from the material. The material is characterized by comprising the following components in percentage by weight: 35-40 percent of fly ash, 35-40 percent of wollastonite, 15-30 percent of polyvinyl chloride resin, 0.2-2.5 percent of carbon black, 1-3 percent of zinc borate and 3-6 percent of composite calcium-zinc modifier. Through high-temperature coupling and crosslinking, polymerization condensation reaction of an inorganic matter and an organic matter is realized; the material is granulated to form particles after a high molecular structural function is changed; a special equipment mould is applied to perform extrusion molding; and then a novel calcium-wood composite board with superior performance is formed after a three-dimensional pattern is embossed on the surface.

Description

technical field [0001] The invention is a novel calcium-wood composite material and relates to a composite board made of the material. Background technique [0002] With the improvement of people's living standards, the demand for environmentally friendly, energy-saving and beautiful decorative high-grade materials is constantly increasing, especially the floor with natural wood grain is more and more popular among consumers. The materials for decoration on the market have stone, plastic wood and wood etc., but there are many deficiencies in the composite panels made by these materials. [0003] Pure wood has the disadvantages of being afraid of water, easy to moth, flammable and easily deformed, and it consumes a lot of forest resources. Stone has the disadvantages of difficult construction, slippery, damp, and radiation. Plastic wood has the disadvantages of easy deformation and low product grade. Therefore people eagerly hope that a kind of decorative material that is ...
