Abstract

The invention belongs to the design and manufacturing technology of environment-friendly composite material foaming plate, referring to a vegetable fiber-reinforced biomass resin-based foam plate and a preparation method of the foam plate. A light and high-performance composite material foam plate is manufactured by using vegetable fibers such as ramee, flax, hemp and jute as reinforced body, and loading expansion biomass resin and biomass epoxy resin. The preparation method comprises the steps of manufacturing a fiber felt with a certain thickness by needling or by using adhesive; and carrying out fire retarding or / coupling treatment on the chopped fiber felt; preparing epoxy resin by a MPA (maleopimaric acid anhydride) rosin-based epoxy resin curing agent; preparing epoxy resin into water-based suspension; adding 5-15% (mass percentage) of a microcapsule foaming agent to the suspension; fully immersing the treated fiber felt in the resin suspension, and removing the excess resin; finally, heating the chopped fiber felt immersed by resin for 10-15min in an oven at a certain temperature; after the resin cures, obtaining the vegetable fiber-reinforced biomass resin-based foam plate.

Description

technical field [0001] The invention belongs to the design and manufacturing technology of a resource-friendly and environment-friendly composite material foam board, and relates to a continuous natural plant fiber and using the fiber as a carrier to carry expanded biomass resin and biomass epoxy resin to manufacture lightweight The plant fiber reinforced biomass resin-based foam board of high-performance composite material foam board and its preparation method. Background technique [0002] Generally speaking, foam materials have the advantages of low density, moderate and adjustable mechanical properties. Depending on material selection and structural design, this material can also have functional uses such as shock absorption and noise reduction, low thermal conductivity and heat insulation, filling, etc., so it can be used in cabins or interiors, typically including vehicles, ships, trains, and airplanes , home improvement furniture, etc. However, insufficient rigidity...
