Abstract
The invention discloses a preparation method of a composite fabric and PU (polyurethane) foam seat cushion. The preparation method comprises steps as follows: (1) a fabric is selected; (2), a template is selected; (3), the fabric is sewn and attached to the template; (4), a mold is heated to 60-70 DEG C and opened, the fabric attached to the template is placed into the mold, and the mold is closed and tightly pressed; (5), the template is taken away after vacuum pumping is performed for 5-15 seconds; (6), a PU foam seat cushion composite is prepared and cast; and (7), the mold is opened after curing. According to the preparation method, two production procedures for producing the fabric and foams are simplified into one procedure, so that the production cost is saved greatly, and the production efficiency is improved; and the prepared foam seat cushion is uniform and fine in foam cell, and has excellent heat-insulating property and good physical properties of indentation hardness, compression set and the like.
Description
Technical field
The invention belongs to chemical technology field, be specifically related to a kind of preparation method of composite material PU foam seat cushions.
Background technology
The vapour automobile headrest that contains fabric is the following two procedures of needs when producing: first make the soft bubble of high resilience cold-curing, second operation work is coated fabric.If fabric is placed directly in mould and is foamed, generate fabric and the integrated goods of foam, so just conventional twice production process can be reduced to a procedure, thereby greatly save production cost, enhance productivity.
Due to needs polyurethane foam and fabric are put in mould together with foaming, therefore, different from other foamed plastics for the composition of the composite material polyurethane foam pad of resting the head on.For guaranteeing that fabric polyurethane foam pad has corresponding performance, it is important that its preparation technology's optimization also becomes.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art the preparation method of the composite material PU foam seat cushions that provides a kind of and save production cost, enhance productivity.
Above-mentioned purpose of the present invention is achieved by the following scheme:
A preparation method for composite material PU foam seat cushions, comprises the steps:
(1), the fabric of select tape fabric overlay;
(2), select preformed plastics template, described template thickness is 0.2～0.3mm, the profile of shape and seat cushion mould matches;
(3), the fabric of step (1) is made on the plastics template that is fitted in step (2);
(4), seat cushion mould is warming up to 60～70 ℃, open mould, the fabric with the laminating of plastics template of step (3) is put into mould, closing molding compresses;
(5), vacuumize after 5～15s, take plastics template away;
(6), preparation and cast polyurethane foam pad compound material, compound material is mixed by the raw material of following weight portion:
80～120 parts of polyether-tribasic alcohols, 0.1～1 part of organic silicon surfactant, 0.5～2 part of sorbierite PPG, 2～5 parts, water, 0.1～1 part of amine catalyst, MDI40～60 part, 80～120 parts of isocyanates;
(7), die sinking after slaking, can make composite material PU foam seat cushions.
As improvement of the present invention, above-mentioned polyurethane foam pad compound material is made by the raw material of following weight portion:
100 parts of polyether-tribasic alcohols, 0.5 part of organic silicon surfactant, 1 part of sorbierite PPG, 3 parts, water, 0.5 part of amine catalyst, MDI50 part, 100 parts of isocyanates.
Compared with prior art, the beneficial effect that the present invention has is:
The present invention is reduced to a procedure by generation fabric and foam twice production process, thereby greatly saves production cost, and has improved production efficiency.The abscess of the foam seat cushions of preparation is even, fine and smooth, and heat-proof quality is good, and the physical properties such as indentation force deflection, compression set are good, and product surface is difficult for forming fold, has reduced substandard products and the percent defective of product.
