Abstract
The invention relates to a production method of an automobile trunk carpet, comprising the following steps: (1) spraying glue and laminating: placing a terylene blanket in a positioning and laminating tooling, positioning the blanket, evenly spraying glue on one side of the positioned terylene blanket, and laminating the terylene blanket with one side of a polypropylene hollow board to obtain a semi-finished product, wherein the glue spraying amount is 90-110g/m<2>; (2) evenly spraying glue on the other side of the polypropylene hollow board of the semi-finished product, and the sticking a non-woven cloth on the other side of the polypropylene hollow board after glue spraying, wherein the glue spraying amount is 90-110g/m<2>; (3) molding and punching: placing the semi-finished product after the non-woven cloth is stuck on in a die for molding and punching, wherein the molding pressure is 7-9Mpa and the molding time is 55-65s; (4) covering: covering the rims of the semi-finished product after molding and punching by covering clothes; and (5) installing and inspecting accessories: adhering cotton pads and installing stay cords on the covered semi-finished product to obtain a finished product. The method in the invention has saved production cost, is environment-friendly and has no pollution.
Description
Technical field
The present invention relates to a kind of working method of car trunk carpet, it is especially a kind of to belong to the automotive upholstery technical field.
Background technology
Automotive upholstery generally is installed on motorcar interior, plays and beautifies, protects and effect such as sound insulating and absorbing.More and more pursuing High Performance, environment-friendly type, energy-saving, lightweight, personalized epoch, the exterior trim of automobile is the same with the performance of automobile, has more and more obtained people's attention.Therefore also increasingly high to the requirement of automotive upholstery.In the prior art, performance figure such as the low weight of baggage compartment carpet, high strength, high-mechanic, sound absorption properties become bottleneck, are restricting the development of baggage compartment carpet.Existing its shortcoming of baggage compartment carpet is: weight is big, price is high, noise is big, shrinkage distortion is big etc., can not satisfy the performance requriements of some automobile to baggage compartment carpet.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, provide that a kind of cost is low, the working method of free of contamination car trunk carpet.
According to technical scheme provided by the invention, the working method of said car trunk carpet may further comprise the steps:
(1) the spray sticker closes: terylene face blanket is put into location applying frock, at first with face blanket location, simultaneously spray glue uniformly at the terylene face blanket of having good positioning, spray glue amount is 90～110g/m
2The one side applying of terylene face blanket and polypropylene hollow sheeting is obtained half-blank;
(2) on the another side of semi-finished polypropylene hollow sheeting, evenly spray glue, stick nonwoven fabrics behind the spray glue; Spray glue amount is: 90～110g/m
2
(3) molding press cutting: the half-blank that will stick nonwoven fabrics is put into mould and is carried out molding press cutting, and forming pressure is: 7～9mpa; Molding time is: 55～65 seconds;
(4) bound edge: the semi-finished periphery behind molding press cutting is carried out bound edge with edge-covering cloth;
(5) annex is installed, is checked: be stained with the pad cotton on the half-blank after handling through bound edge, install stay cord, obtain finished product; Finished product is after check, and the surface does not have breakage, aberration, stain, and product does not have distortion, the vanning warehouse-in.
Said glue is hot-fusible pressure-sensitive adhesive.
The temperature of said glue is: 170～180 ℃, spray glue air pressure is: 4.0～5.0mpa.
The invention solves performance figure such as baggage compartment carpet high strength, high-mechanic, sound absorption properties, reached international forward position level; Greatly reduce the weight of baggage compartment carpet, satisfied the requirement of car load light-weight design; Material adopts PET face blanket and PP hollow sheeting, make product aspect sound-absorbing and the reduction grammes per square metre large increase arranged, and product is not yielding, moulding Detroit automation, process stabilizing; The rigidity of product is high, and intensity is big, can not fracture, ftracture; Practiced thrift manufacturing cost; The product whole process of production does not have objectionable impurities to produce, and belongs to environment-friendly products.
