Hard environment-friendly flame-retardant polyvinyl chloride foaming board and manufacturing method thereof

Abstract

The invention discloses a hard environment-friendly flame-retardant polyvinyl chloride foaming board and a manufacturing method thereof. The foaming board comprises a lower layer. A second surface layer is connected to the upper surface of the lower layer. A third surface layer is connected to the upper surface of the second surface layer. An ASA resin layer is connected to the upper surface of the third surface layer. A protective film layer is arranged on the upper surface of the ASA resin layer. The lower layer polyvinyl chloride foaming material is prepared from, by weight, 100 parts of polyvinyl chloride, 6 parts of a stabilizing agent, 10-20 parts of aluminum hydroxide, 10-30 parts of flame retardant, 10-20 parts of an acrylic ester processing modifier, 5-15 parts of an impact modifier, 5-50 parts of a filler, 1-5 parts of a chitosan oligosaccharide, 0-1 part of a yellow foaming agent, 2-6 parts of a white foaming agent, 2-4 parts of a lubricating agent, and 0-2 parts of pigment. The hard environment-friendly flame-retardant polyvinyl chloride foaming board has the advantages of being high in hardness and low in density, resisting to water and dampness, resisting to flame, being environmentally friendly and the like, is easy to implement, and has the good market prospect.

Description

technical field [0001] The invention belongs to the field of polyvinyl chloride processing, in particular to a rigid environment-friendly flame-retardant polyvinyl chloride foamed board. Background technique [0002] In recent years, with the development of the national economy, decorative panels have been widely used. Decorative panels can be divided into outdoor decorative panels and interior decorative panels. Because PVC material has excellent corrosion resistance and smooth and shiny appearance, it also has insulation properties and Low prices and other special features are widely used in panels or decorative panels. The development of emerging industries means new demand, such as the advertising industry, home decoration industry, etc. The materials used have also undergone different changes. With the upgrading and optimization of materials, because the rigid PVC low-foaming board is suitable for home kitchens, bathrooms, and partitions, its service life is much longer...

AI Technical Summary

Problems solved by technology

The traditional wood and high-density boards used in the decoration industry are low in price but poor in quality; solid wood composite boards are expensive and not flame-retardant; light box cloth and KT boards are light in weight but fragile; There is always a need for the development of more cost-effective panels in the market
