New macromolecule fiber composite material

Abstract

The invention discloses a new macromolecule fiber composite material which is prepared by the following components in parts by weight, 40-100 parts of plant fiberfill, 60-100 parts of plastic base material, 3.5-5 parts of heat stabilizer, 1-2 parts of plasticizer, 1.6-2 parts of lubricating agent, 4-8 parts of modifying agent, 1-3 parts of compatilizer, 2-3 parts of coupling reagent, 1-5 parts of super dispersing agent, 1-4 parts of positive ion surface active agent, 1-1.8 parts of foaming agent, 1-5 parts of blowing promoter, 0.3-1.2 parts of antioxygen, 1-10 parts of cross-linking agent, 1-20 parts of nucleating agent, 0.8-1 part of viscosity reducer, 0.8-1 part of tackifier and 3.2-13.4 parts of other auxiliaries. The new composite material can not easily cause wet swelling and air shrinkage, and is low in expansibility and water absorbability, so that the prepared product has good stability.

Description

technical field [0001] The invention relates to the field of polymer materials and products derived from biomass, in particular to a new polymer fiber composite material. Background technique [0002] The new polymer fiber composite material is a type of composite material obtained by blending and extruding plant fibers (including wood chips, sisal powder, bagasse, bamboo chips, hemp stalks, fruit shells, etc.) and plastics, and is widely used in civilian applications. Architectural decoration, vehicles and ships, national defense and other industries. This kind of material has good processability, and has the characteristics of anti-corrosion, beautiful, generous, etc., but its disadvantage is that the mechanical properties are not good, but it can be modified by surface modification of plant fibers and plastics, and adding different additives. agents to improve. The invention patent with the publication number CN101921491A discloses a wood-plastic composite material, whi...
