Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with specific embodiments. Examples are shown in Table 1, and performance test results are shown in Table 2.

[0018] The wood powder described in the examples is bamboo powder, which is treated with a titanate coupling agent before use. The specific treatment process is: dilute the titanate coupling agent with alcohol, the ratio of alcohol to coupling agent is 5:1, first Dry the bamboo powder, smash it, then put it into a high-speed mixer, stir at a low speed, add the mixture of alcohol and coupling agent from the top liquid injection hole, mix for 5 minutes, let the alcohol fully evaporate; the above aluminate The weight ratio of coupling agent to bamboo powder is 1:100.

[0019] The processing composite strengthening agent is mixed with magnesia and montmorillonite in a ratio of 1:2, and treated with aluminate coupling agent. The treatment steps are as follows: first dilute the aluminate ...

Abstract

A high-mechanical-property wood-plastic composite board composition is prepared from, by weight, 100 parts of polyvinyl chloride resin, 5-8 parts of a calcium zinc stabilizer, 20-30 parts of wood powder, 3-5 parts of a lubricant, 9-10 parts of a treatment composite reinforcing agent and 5-10 parts of a plasticizer. The wood-plastic composite board composition has advantages of high tensile strength, impact strength and vicat softening temperature.

Description

technical field [0001] The invention relates to a polymer composite material, in particular to a wood-plastic composite board composition with excellent mechanical properties and a preparation method thereof. Background technique [0002] Wood-plastic composite board is a kind of composite material composed of wood powder and resin matrix, which can realize the large-scale utilization of wood powder. However, wood powder is a polar fiber material, while ordinary polyolefin resin is a non-polar resin, and the two are difficult to be compatible. demanding areas. Contents of the invention [0003] Aiming at the problem of poor mechanical properties of composite boards, the invention proposes a wood-plastic composite material with high mechanical properties. [0004] The present invention achieves the technical goal through the following technical proposals. A wood-plastic composite board composition with high mechanical properties is made of the following components in part...
