Abstract

A continuous fiber reinforce polyurethane foaming material and a relative production method relate to a polyurethane foaming material, wherein the continuous fiber reinforce polyurethane foaming material has strong rigidity, strength and shock resistance to produce foaming polyurethane material with reinforced glass fiber, which eliminates breaking and premixing with any component of polyurethane, is directly mixed and immersed with polyurethane mixture in an immerser and is foamed and shaped continuously, and contains A, B and C components. A comprises polyatomic alcohol, foaming agent, catalyst, foaming stabilizer, chain extender and adjuvant, B is polyisocyanate, C is fiber material. The preparation method comprises mixing the materials of A in A pot, the materials of B in B pot, immersing fiber via an immerser with the mixture discharged from a high-speed pouring head, feeding immersed material into a continuous foaming mold to be foamed and solidified, cooling, removing mould, taking off and cutting to obtain final product.

Description

technical field [0001] The invention relates to a polyurethane foam material, in particular to a polyurethane foam material reinforced by continuous fibers and a manufacturing method thereof. Background technique [0002] Polyurethane foam has the advantages of low density, light weight, good heat insulation and sound insulation effects. However, polyurethane foam used as a load-bearing structural material requires excellent strength, modulus and dimensional stability in addition to the above advantages. Compared with other materials, the technical indicators such as bending strength and impact strength of polyurethane foam cannot meet the requirements of use, thus limiting its wide use. In order to make up for this defect, the method of adding reinforcing agent is used to improve its strength. The reinforcement agents reported in recent years can be divided into two types: one is particles, including glass microspheres, silica particles, calcium carbonate and graphite, et...
