Abstract

The invention discloses a high-strength wood-plastic board and a preparation method thereof. The high-strength wood-plastic board comprises components in parts by weight as follows: 50-80 parts of sisal dregs, 40-80 parts of waste plastics, 10-25 parts of modified phenolic resin, 6-10 parts of mineral fiber, 5-10 parts of pentalyn, 8-12 parts of nano calcium carbonate and 8-15 parts of an auxiliary. The preparation method comprises technological steps of modification pretreatment, high-speed mixing, hot-press molding and cooling for sizing. Comprehensive utilization of resources of the sisal dregs is realized, the prepared wood-plastic board has high compressive strength and wear resistance, the cost is reduced, and the service life of the wood-plastic board is long. The high-strength wood-plastic board and the preparation method have the advantages of simpleness in processing technology, short processing time, low cost and the like, and the wood-plastic board is applicable to industrial production.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to a high-strength wood-plastic board and a preparation method thereof. Background technique [0002] The existing reserves of non-renewable resources on the earth are very limited. With the rapid development of the plastic industry, the "white pollution" caused by plastic products has brought great harm to human production and living environment. In order to solve the shortage of raw materials and environmental problems, people gradually shift their attention to the renewable resources on the earth. Plant fiber material is a kind of natural polymer material and an inexhaustible resource. The potential advantages of plant fiber used in composite materials have attracted more and more attention. It is cheap, low density, and has a high elastic modulus, which is similar to inorganic fibers, and its biodegradability and renewability are the most prominent. The advantages. ...
