Abstract

The present invention relates to a styrene-base wood-like material formula, wherein the styrene-base wood-like material comprises, by weight, 100 parts of general purpose polystyrene, 20-40 parts of high impact resistance polystyrene (HIPS), 10-15 parts of a styrene butadiene rubber, 2-5 parts of an inorganic filling material, 0.5-1.5 parts of a foaming agent, 0.5-3 parts of a cell regulator, 0.2-0.5 part of an ultraviolet absorber, 0.5-3 parts of a lubricant, 0.4-0.7 part of a wood aroma agent, 0.7-1.3 parts of a dispersing agent, and 0.5-2 parts of a coloring agent. According to the present invention, compatibility between the main material and the auxiliary material is avoided, and the problems of large size difference, uneven distribution and the like of the cells in the traditional wood plastic wood-like material are solved so as to further improve water resistance and moisture resistance of the wood-like material, reduce material density and brittleness, improve mechanical strength and prolong a service life.

Description

technical field [0001] The invention relates to a material formula, in particular to a styrene-based imitation wood material formula. technical background [0002] Wood profiles are the main materials for indoor and outdoor furniture, pavement or decoration, but the growth cycle of wood is long, resources are few, and production costs are high. There are many products that use composite materials instead of wood on the market today. Wood-plastic composite material is an environmentally friendly material, which has the advantages of plant fibers and plastics, and can cover almost all fields of use of logs, plastics, plastic steel, aluminum alloys and other similar composite materials. [0003] At present, most plastic wood products use polyvinyl chloride (PVC) resin as the matrix. Because of its obvious advantages such as low cost, good mechanical properties, and good touch, it is widely used in actual production, but at the same time its non-recyclable, chemical additives, ...
