Abstract
The invention discloses nylon fiber-reinforced polyurethane foam and a preparation method thereof, and belongs to the technical field of materials. The polyurethane foam is prepared from the following raw materials by weight: 65 to 80 parts of a polyurethane emulsion, 11 to 20 parts of nylon fiber, 2 to 7 parts of di-isopropyl peroxydicarbonate, 3 to 8 parts of trimethylol propane, 2 to 5 parts of polyisobutylene succinimide, 2 to 6 parts of aluminum sulfate, and 5 to 10 parts of n-heptane. The preparation method comprises the following steps: (1) weighing; (2) placing the weighed raw materials into an injection molding machine; (3) cooling molding. The polyurethane foam prepared according to the method is higher in compression resistance and temperature resistance; moreover, as the polyurethane foam is formed integrally through injection molding, the performance of the polyurethane foam is guaranteed effectively.
Description
Technical field
The invention belongs to field of material technology, particularly a kind of nylon fiber reinforced polyurethane foam and preparation method thereof.
Background technology
Urethane foam, be that isocyanic ester and oxy-compound are made through polymerization foaming, can be divided into soft and hard two class by its hardness, wherein soft is principal item.In general, it has splendid elasticity, flexibility, elongation and compressive strength; Chemical stability is good, resistance to many solvents and oils; High abrasion resistance, comparatively large 20 times of natural sponge; Also having the excellent performance such as processibility, heat insulating ability, binding property, be a kind of cushioning material of excellent property, but price is higher.
Urethane foam is except expensive, and outside raw material is in short supply, maximum defect is that its heat resistance and fire resistance are poor, and temperature uses higher than under the environment of 100 DEG C, comparatively unfavorable.
Modified rigid polyurethane foam, is one of effective means of reinforced polyurethane foam performance, especially makes up the heat resistance of urethane foam.
Nylon fiber can be used for the enhancing of PUR porous plastics.This is because the polarity of nylon molecules chain is strong, and have good Intermolecular Forces between PUR ,-the NH-in addition on nylon main chain can form hydrogen bond with the-C=O on PUR, increases intermolecular reactive force further.Therefore nylon fiber modification PUR porous plastics can obtain good effect.
