Flame-proof formaldehyde-free wood-plastic wall plate and preparation method thereof

Abstract

The invention provides a flame-proof formaldehyde-free wood-plastic wall plate, and relates to the technical field of wood plastic wall plate processing production. The wall plate is characterized by being prepared from the following components: 20-29 percent of PVC powder, 18-30 percent of calcium carbonate powder, 14-27 percent of plant powder, 7-15 percent of polyaniline, 5-10 percent of PVC adhesive, 7-14 percent of ethylbenzene potassium salt and 6-13 percent of methyl propyl ester. The method is reasonable and has a clear proportion, and the wood-plastic wall plate does not contain formaldehyde and can be used for proofing flame.

Description

Technical field: [0001] The invention relates to the technical field of wood-plastic wallboard processing and production, in particular to a fireproof, formaldehyde-free wood-plastic wallboard and a preparation method thereof. Background technique: [0002] Wood-plastic wallboard is a new type of environmentally friendly wood-plastic composite material product. Wood phenol produced during the production of medium and high-density fiberboards is added to recycled plastics to make wood-plastic composite materials through granulation equipment, and then extruded. Group made of wood-plastic wall panels. [0003] The main material of wood-plastic outdoor wallboard is PE and wood powder or bamboo powder. After adding additives and mixing at high speed, it is granulated, and then the pellets are extruded into molding materials with an extruder. This kind of wallboard can be used for garden landscape , villas and other outdoor platforms. [0004] However, wood-plastic wallboards o...
