Embodiment 1

[0020] In this embodiment, the weight-reducing composite wood-plastic profile is composed of the following components by mass percentage:

[0021]

[0022] Wherein, the foaming agent is Matsumoto microsphere foaming agent or azo foaming agent. The lubricant is maleic anhydride grafted polyethylene wax. Increases fluidity through the combined action of talc and lubricants, while increasing the compatibility of wood flour and other ingredients.

[0023] The preparation method of the weight-reducing composite wood-plastic profile described in this embodiment comprises the following steps:

[0024] S1, put wood powder, compatibilizer, talcum powder, lubricant, toner, antioxidant, antifungal agent, high-density polyethylene into a high-speed stirring furnace and stir for at least 10 minutes, and then put it into a 75-square-meter double-water pull bar to make The granules are prepared in the granulator for standby, and the preparation temperature is controlled at 160°C-200°C; ...

Abstract

The invention discloses a reduced-weight composite wood-plastic profile and a preparation method thereof. The reduced-weight composite wood-plastic profile comprises the following components: wood flour, a compatilizer, talcum powder, a lubricant, toner, an antioxidant, a mildew preventive, high-density polyethylene and a foaming agent. Through the synergistic effect of the preparation raw materials, the strength of the prepared wood-plastic profile is guaranteed, meanwhile, the total amount of the profile is reduced, the surface temperature is reduced, and a user feels more comfortable when using the wood-plastic profile.

Description

technical field [0001] The invention relates to the field of wood-plastic production, in particular to a weight-reducing composite wood-plastic profile and a preparation method thereof. Background technique [0002] Wood-plastic composites are new functional materials obtained by compounding wood materials with thermoplastic or thermosetting plastics. Wood-plastic products have the advantages of both plastic and wood, and have positive social and ecological effects in reducing environmental pollution and protecting forest resources. , Auto parts, electrical casings, interior decoration, children's toys, decorative ornaments, household goods, packaging materials, etc., have a wide range of applications. And existing wood-plastic material quality is heavier, and surface temperature is high after sunshine. Contents of the invention [0003] Aiming at the defects of the above prior art, the main purpose of the present invention is to overcome the deficiencies of the prior ar...
