Abstract
The invention relates to a production technology for an upright column of an acoustic part of an automobile, which comprises the following steps: (1) placing a polyurethane composite board into an oven and then heating, wherein the heating time is 100-200 seconds and the oven temperature is 120-200 DEG C, and (2) performing cold-pressing forming on the polyurethane composite board after being heated in the step (1), wherein a cold-pressing forming pressure is 5-15 MPa and a dwell time is 5-10 minutes. From up to down, the polyurethane composite board comprises compound materials, glass fiber felts, polyurethanes, glass fiber felts and non-woven fabrics in turn, wherein the compound materials are the materials made of compounded terylene and polyurethane foam. The upright column of the automobile according to the invention has the advantages of light weight, low cost, zero limitation on low-temperature brittleness, small inhibition during an unfolding process of an air bag, usage in the form of matching with a headlining and the air bag of the automobile, and capability of promoting the safety of the automobile.
Description
Technical field
The present invention relates to a kind of production technology of car acpistocs parts column, especially a kind of column production new technique that is used with automobile side gas curtain.
Background technology
Automobile stand column polypropylene (PP) plastic pellet often processes through drying by the fire the dry back injection moulding of temperature, has that glossiness is good, hardness is big, rigidity is strong, advantages such as good heat resistance, so have extensive utilization in the automotive upholstery industry.High speed development along with automobile industry; Car speed is more and more faster, and traffic accident emerges in an endless stream, and people are also corresponding increasingly high to the requirement of vehicle safety performance; Generally begin the installation side air bag on the automobile, so that the protection head of passenger is avoided bump when occurrence of traffic accident.But, because there is the performance deficiency of black brittleness in the PP plastics, can be chipping when the gas curtain explosion; The fragment that produces is strong as the bullet impulsive force; Air bag does not only have protective effect, on the contrary can serious harm passenger life security, must carry out the low temperature toughening modifying to PP; But cost is very high, and effect is not clearly.Therefore, the compound polyurethane material that research cost is cheap, low-temperature impact resistance is excellent has great importance as automobile stand column.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art; Provide a kind of in light weight; Cost is low, the production technology of the car acpistocs parts column of no black brittleness restriction, and the inhibition during to air-bag deployment is little; Can be used with ceiling and safe automobile air bag, improve vehicle safety performance.
According to technical scheme provided by the invention, a kind of production technology of car acpistocs parts column, characteristic are to comprise following processing step:
(1) put the Rigid foam polyurethane material into the baking oven heating, be 100 ~ 200s said heat time heating time, and oven temperature is 120 ~ 200 ℃;
(2) with the typing of colding pressing of the Rigid foam polyurethane material after the said heating of step (1), cold moudling pressure is 5 ~ 15MPa, and the dwell time is 5 ~ 10min.
Said Rigid foam polyurethane material is followed successively by composite material, glass mat, polyurethane, glass mat, nonwoven from top to bottom; Said composite material is the lining that terylene and polyurethane foam are composited.
Automobile stand column of the present invention is in light weight, and cost is low, the restriction of no black brittleness, and the inhibition during to air-bag deployment is little, can be used with ceiling and safe automobile air bag, improves vehicle safety performance.
