Example Embodiment

[0025] Example 1

[0026] The manufacturing method of wood plastic board is carried out as follows:

[0027] (1) Material preparation: mix 30 parts of the main material and 50 parts of the filler according to the weight ratio. The main material is a mixture of 18 parts of waste tires and 12 parts of waste plastics: the filler is wood flour and calcium carbonate, wood flour: The weight ratio of calcium carbonate is 7:1;

[0028] (2) Raw material pretreatment: Put the main material prepared in step (1) in a boiler for melting, control and adjust the temperature to maintain the temperature at 40-240°C, so that the main material after melting has neither calcification nor carbonization;

[0029] (3) Mixing: Add the filler prepared in step (1) to the melted main material in step (2), stir evenly, flow into a pipe, squeeze, and set up a rectangular outlet at the outlet. The outlet specifications are based on Suppose the board specification on the factory is a rectangle with a length of 126...

Abstract

The invention discloses a wooden and plastic plate and a manufacturing method thereof. The method comprises the following steps: (1) preparing raw materials; (2) pretreating the raw materials; and (3) mixing and extruding the pretreated raw materials to mould the plate. The plate of the invention is manufactured by taking waste tires, waste plastics, waste leather and the like as the raw materials, has very good water-proofing property after being molded, also has certain elasticity and also contains no formaldehyde. The manufacturing method has the advantages of simpleness, low production cost, high yield, and well recovery of the waste tires, waste plastics, waste leather and the like.

Description

technical field [0001] The invention belongs to a board and a manufacturing method thereof, in particular to a wood-plastic board and a manufacturing method thereof. Background technique [0002] At present, the composite wood flooring is a multi-layer layered structure, and its base layer is formed by bonding wood powder or bamboo powder or wood veneer with melamine glue, and the melamine glue will volatilize when the external temperature rises. Formaldehyde is a relatively large pollution and harmful to the human body. [0003] Waste tires or waste plastic packaging products and waste leather shoes are very polluting to the human environment, have little value, and are huge in quantity, so the recycling cost is low and the sources are wide. With the continuous progress and development of society, there will be more and more of these waste items. [0004] After research, it is found that reasonable recycling and utilization of these waste products to make a board with good...
