Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific embodiments with reference to the accompanying drawings, so as to better understand the present invention.

[0022] The high-strength resin-plastic composite material with excellent foaming performance based on PE in this embodiment includes 25kg of wood flour particles, 30kg of polyethylene, 3kg of foaming agent, 30kg of epoxy resin filler, 4kg of lignin, and 0.3kg of lubricant EBS , stearic acid 2kg, antioxidant 1010 0.2kg, compatibilizer maleic anhydride grafted PE 2kg, ACR impact modifier 0.5kg, colorant iron oxide 3kg

[0023] The specific process steps of the above-mentioned PE resin-plastic composite material are as follows:

[0024] 1) Weigh the raw materials according to the ratio in the formula, and put them into a barrel A except for wood powder and lignin.

[0025] and lignin into barrel B. Both were dried in a dryer for 30 min.

[0026] 2) Using two-step feeding method, no...

Abstract

The invention provides a PE resin-plastic material and a preparation method thereof. The PE resin-plastic material is prepared from wood flour particles, polyethylene, a foaming agent, epoxy resin filler, lignin, a lubricating agent, stearic acid, an antioxidant, a compatilizer, an anti-impact processing modifier and a coloring agent. A secondary feeding method is adopted in the preparation method, and therefore the integrity of wood fiber is fully guaranteed. By selecting a reasonable formula and an appropriate technology, the interface compatibility is greatly improved, the mechanical property is significantly improved, the ductility is improved by 23% compared with that of an existing product on the market, the density is reduced by 36%, cost is reduced by 1/3, and the high practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a PE plastic material with excellent foaming performance and a preparation method thereof. Background technique [0002] Lipoplastic composite material is a kind of polymer composite material with excellent performance emerging in recent years. It has the dual advantages of both wood and plastic, not only has the characteristics of acid and alkali resistance, no rot, low water absorption, easy to clean, etc., but also its mechanical properties are greatly improved due to the existence of wood powder. However, there is a common problem with this kind of material, that is, the interface compatibility between wood flour and plastics is poor, the ductility is poor, and the density is high. This is also a direction that everyone has been paying attention to. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned prior art, the p...
