Problems solved by technology

At present, most of the polymer composite boards on the market are compounded by adding materials such as calcium carbonate, wood powder, and cellulose to the polymer. However, due to the addition of wood powder and calcium carbonate composite materials at the same time, foaming cannot be performed, resulting in decorative The quality of the plate is high, the cost is high, and it cannot be widely used in the market

Abstract

The invention discloses a silicate-modified PVC foamed composite decorative sheet and a manufacturing method thereof. The manufacturing method is mainly used for manufacturing a decorative sheet used in occasions such as a family, an office, a shopping mall and a meeting, and belongs to the technical field of composite materials. The silicate-modified PVC foamed composite decorative sheet mainly comprises three layers, namely a decorative layer, a foaming layer and a supporting layer, wherein the supporting layer is mainly prepared from silicate inorganic filler, polyvinyl chloride and a processing aid; the foaming layer is mainly prepared from silicate inorganic filler, polyvinyl chloride, a foaming agent and a processing aid; the decorative layer is mainly prepared from silicate inorganic filler, polyvinyl chloride, a color masterbatch and a processing aid. The decorative sheet has the advantages of being free of toxicity and odor as well as formaldehyde, being capable of preventing water, dampness, worm damage, light mass and high surface decoration property, being nailable, sawable and planeable, being capable of reducing the consumption of wood and macromolecular polymers, and being relatively high in strength and relatively long in service life.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a silicate-modified PVC foamed composite decorative board and a manufacturing method thereof, which can be used to make decorative boards used in occasions such as homes, offices, shopping malls, and conferences. Background technique [0002] In homes, offices, shopping malls, conference rooms and other occasions, decorative panels such as desktop panels, countertops, ceiling panels, and window sill panels are often used, generally made of artificial panels such as solid wood panels, veneered plywood, particleboard, high-density panels, particle panels, and reinforced panels. , There are also gypsum boards, marble boards, artificial marble boards, etc. However, the solid wood board is expensive, and it may be moth-eaten, corroded, and waterproof and moisture-proof during use; It will continue to pollute indoor air and endanger human health; the strength of gypsum boa...
