Abstract

The invention belongs to the technical field of a high-molecular material and discloses a polyamide wood-plastic composite material and a preparation method thereof. The material is prepared from the following components in parts by weight: 100 parts of nylon 6, 30-100 parts of wood filler, 5-15 parts of inorganic filler, 1-5 parts of processing aid, 0-15 parts of compatilizer, 0.5-3 parts of coupling agent, 0.2-1 part of antioxygen and 0-3 parts of lubricating agent. The preparation method comprises the following steps of: (1) adding 100 parts of nylon 6, 0-15 parts of compatilizer, 1-5 parts of processing aid and 0.2-1 part of antioxygen into a high-speed mixer to uniformly mix them at a high speed so as to obtain a mixed material; (2) adding 30-100 parts of wood fillers, 5-15 parts of inorganic fillers, 0.5-3 parts of coupling agent and 0-3 parts of lubricating agent into the high-speed mixer for uniform mixing at high speed so as to obtain a mixed material; and (3) adding the mixed material obtained in step (1) and the mixed material obtained in step (2) into a double-screw extruder for extrusion-pelleting so as to obtain a polyamide wood-plastic composite material. The material provided by the invention has better intensity and flowability, and can be injection-molded.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, and relates to a polyamide wood-plastic composite material and a preparation method thereof. Background technique

[0002] Most of the wood-plastic composite materials currently on the market are based on traditional polymers such as polyvinyl chloride, polypropylene, and polyethylene. However, due to the large polarity difference between these polymer matrices and wood fillers, the compatibility between the two Poor performance and insufficient interfacial force have resulted in the disadvantages of low mechanical properties of wood-plastic composite materials, and the material fluidity is not good when the filling amount is high, and it is generally difficult to injection molding. Products with low strength requirements greatly limit the application of wood-plastic composite materials.

[0003] Nylon 6 material has obvious advantages over polyvinyl chloride, polypropylene, polyethyle...
