Description
Technical field:
The present invention relates to car roof sound insulation technical field, is a kind of riding roof sound insulating pad top cover buttress brace and production method thereof specifically.
Background technology:
Riding roof sound insulating pad-top cover buttress brace is installed in the car steering cabin on the roof panel beating, is a vitals of high-grade automobile, plays sound-absorbing, heat insulation, fire-retardant, the effect strengthened; But in fact vehicle noise insulation pad generally is to be made of the non-weaving cloth that the waste spinning fiber process becomes, and the waste spinning acoustic material has good sound absorption, heat insulation, damping, effect such as fire-retardant but the effect that do not have roof to strengthen; Traditional roof buttress brace mostly is aluminium alloy or steel plate is made, general passenger car should the design and installation sound insulating pad design and installation top cover buttress brace again, cost height, weight are big, are unfavorable for the light-weighted development of automobile.In addition, there are indivedual vehicles also in consideration roof sound insulating pad and top cover buttress brace to be integrated, but mainly adopt hand spray solvent-based adhesive bonding glass fiber felt in the mode of production of each interior material, have that product weight is big, contaminated environment, problem that labour intensity is big, be unfavorable for that the workman is healthy.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art, and disclose a kind of roof sound insulating pad-top cover buttress brace.
Another object of the present invention provides the preparation method of a kind of roof sound insulating pad-top cover buttress brace.
Cost height when the present invention mainly solves traditional roof sound insulating pad and the split of top cover buttress brace, weight are big, and the two is integrated that back product weight is big, contaminated environment, labour intensity are big, be unfavorable for the problem that the workman is healthy.
In order to achieve the above object, the present invention is achieved in that a kind of roof sound insulating pad-top cover buttress brace, its special character is that it comprises base material PU cystosepiment, establish brown paper and following brown paper respectively at the upper and lower surface of PU cystosepiment, between last brown paper and PU cystosepiment, establish the polyurethane glue-line, setting the polyurethane glue-line between brown paper and the PU cystosepiment down.
The preparation method of a kind of sound insulating pad of the present invention-top cover buttress brace, its special character is to comprise following processing step:
A roller glue: carry out roller glue, the rubber roll temperature on base-material PU cystosepiment two sides: 20～50 ℃, rubber roll height: 6.0～7.0mm, two-sided roller glue amount: 48～58g/m2, glue are environment-protecting polyurethane glue; Can accurately control spread, solve the sound-absorbing in the car, heat insulation, fire-retardant problem;
B sprays demineralized water: the PU cystosepiment that above-mentioned roller glue is crossed sprays demineralized water, and two-sided watering amount: 18～26g/m2 adds curing agent in the demineralized water; Curing agent is amine curing agent, and consumption is the 0.2-1% of demineralized water weight;
The c moulding is sheared: the PU cystosepiment upper and lower faces that will spray demineralized water is spread brown paper respectively, be put in compression molding in the mold heat, mold temperature: 130～140 ℃, adopt one-level venting pressurize, pressurize time-delay I: 12～16S, breathing a mould time: 0.2S, pressurize time-delay II: 18～22S, briquetting pressure: 8～9Mpa makes product possess enough rigidity; Forming process cuts off lateral opening clout simultaneously;
D cooling and shaping: the first shape of the product after the compression moulding is carried out cooling and shaping, cool time: 30～38S.
Compared with the prior art a kind of roof sound insulating pad of the present invention-top cover buttress brace and preparation method thereof has outstanding substantive distinguishing features and marked improvement, and 1, do not use glass fibre in the whole process of preparation, and product has enough rigidity and dimensional stability; 2, in light weight, the good rigidly of product, sound-absorption and heat-insulation; 3, sound insulating pad-top cover buttress brace need not the glass enhancing, weight reduces greatly, has satisfied the car load light-weight design; 4, the product whole process of production is not used harmful substance, is beneficial to environmental protection, belongs to the low-carbon environment-friendly product; 5, employing one-level air bleed technique has solved in the moulding shear history, and edge brown paper cracking problem adopts forming process shearing technique simultaneously, has realized that moulding, cutting one go on foot to finish and enhance productivity.
