Abstract

The invention discloses a corn stalk epidermal fiber wood plastic board and a production method thereof. The board is characterized by being prepared from the following raw materials by weight percent: high density polyethylene, corn stalk epidermal fiber powder, wood powder, nano calcium carbonate, a lubricant, an antioxidant, a solvent and a coupling agent through steps of preparing a die head of the board, extruding by a double-screw extruder, shaping under pressure, and finishing and checking. According to the corn stalk epidermal fiber wood plastic board and the production method thereof, most sugar of the corn stalk is removed, the epidermal fiber powder is degreased, the corn stalk epidermal fiber powder is adopted for volume production, so that the corn stalk epidermal fiber powder does not lower the production quality of the wood plastic board when being added into the wood plastic board, but can greatly lower the production cost of the wood plastic board; furthermore, the production method fully uses local corn stalk resource, thus having both business economic benefits and social benefits; the corn stalk epidermal fiber powder is separately degreased at low temperature, and then is mixed and extruded rapidly in short time, so that the quality of the molded board is guaranteed.

Description

technical field [0001] The present invention relates to a kind of wood-plastic board and the improvement of its production method, specifically a kind of corn straw fiber wood-plastic board which can not only reduce the production cost of wood-plastic board, but also can make full use of local corn straw resources and its production method. Background technique [0002] Wood-plastic panels have good elasticity, and have the same compressive and bending mechanical properties as hardwoods. The hardness is 2-5 times that of wood. Long; by adding additives, it can also be anti-aging, anti-static, and flame-retardant. Therefore, wood-plastic panels have been widely used. The current main raw materials of wood-plastic panels are: 50% wood powder, 25-30% high-density polyethylene, and 10% nano-calcium oxide. Due to the high proportion of wood powder added to this wood-plastic board, the processing cost is high. In order to reduce the amount of wood powder, it can be known from ...
