Abstract
The invention relates to a gluing method on a fabric. The gluing method for a safety air bag fabric is characterized by comprising the steps of placing the safety air bag fabric on an elastic support object and vertically placing a scraper on the safety air bag fabric for scraping, wherein the surface friction coefficient of the elastic support object is smaller than 0.25 and the elasticity modulus of the elastic support object is between 20-30MPa. The elastic support object in the gluing method of the safety air bag fabric can provide pressure between the fabric and a gluing knife, so the gluing quantity is less changed when the fabric tension is changed, horizontal strips are not easily generated, the fabric tension can be adjusted to be very small, and the longitudinal strips are also reduced. The gluing of the low-tightness fabric is realized. The gluing quantity obtained by adopting the gluing method for the safety air bag fabric is more than 50g/m<2>, and the gluing is uniform.
Description
Technical field
The present invention relates to a kind of glue spreading method on fabric.The tension force of fabric when glue spreading method of the present invention can reduce gluing, the easy problem that produces lines while solving low tightness fabric gluing.
Background technology
At present the empty formula glue spreader of cutter is that tension force by regulating fabric is controlled glue-spread, operate fairly simple, convenient, cost is low.In order to obtain high glue-spread fabric, the tension force of fabric is less, and the contact force of fabric and painting cutter is less, can obtain so high glue-spread, but trickle tension variation can cause that larger glue-spread changes, and laterally can produce gluing lines in the time of gluing.The viscosity that improves tension force and glue can obtain high glue-spread fabric under larger tension force, but low tightness fabric easily produces lines in the situation that of hightension, thereby has in appearance longitudinal lines.Therefore conventionally use the method for cutter on roller, can obtain high glue-spread, but the cost of glue spreader is higher, machine construction complexity.
Summary of the invention
The object of the present invention is to provide one to solve the problems of the technologies described above, be applicable to low tightness fabric and obtain the glue spreading method of high glue-spread.
For achieving the above object, the present invention has certain elasticity and obtains compared with the supporter of low-friction coefficient by add one on regular knife formula glue spreader.This supporter is placed on and is coated with cutter below, allows fabric pass through from being coated with between cutter and supporter.
A glue spreading method for air bag fabric, is characterized in that: comprise described substitute
Capsule fabric is placed on elastic supporter, and scraper is vertically placed on the step of carrying out blade coating on described air bag fabric, and the skin-friction coefficient of described elastic supporter is less than 0.25, and the elastic modelling quantity of described elastic supporter is between 20-30MPa.
Described elastic supporter preferably has semicylinder shape or rectangular shape.
The scope of the silica gel viscosity that in a preferred embodiment, described air bag fabric uses is 15-100Pa.S.
Further preferably, the scope of gluing gluing speed used is 10-30m/min.
Above support in the glue spreading method of air bag fabric of the present invention can provide fabric and be coated with the pressure between cutter, glue-spread is changed in the time of fabric tension variation less, be difficult for producing travers, simultaneously the tension force of fabric can regulate longitudinal stripe very little, also less.The invention solves the gluing problem of low tightness fabric.Adopt glue-spread that the glue spreading method of air bag fabric of the present invention obtains more than 50g/ ㎡, and gluing is even.
Brief description of the drawings
Fig. 1 is the equipment schematic diagram of implementing the glue spreading method of a kind of air bag fabric of the present invention.
Wherein: 1-spreading knife; 2-elastic supporter; 3-silica gel; 4-cylinder; 5-fabric.
Detailed description of the invention:
With reference to Fig. 1, the elastic supporter 2 using in the present invention, requires to have certain elasticity, and its skin-friction coefficient is low simultaneously.Normal conditions, also have frictional resistance in the situation that material is exerted pressure over there and produce, and in the time that frictional resistance is excessive, fabric can produce cross-direction shrinkage, produces lines.Elasticity aspect is moderate, and elasticity is too low, and supporter 2 deformation quantities are larger, and after long-term use, shape is difficult to recover, and elasticity is larger, when spreading knife 1 drops to supporter, cushions littlely, easily damages spreading knife 1.Inventor finds, when the skin-friction coefficient of described elastic supporter is less than 0.25, the elastic modelling quantity of described elastic supporter between 20-30MPa time, can reach object of the present invention.Elastic supporter of the present invention can adopt known any material with above-mentioned coefficient of friction and elastic modelling quantity to make, as but be not limited to EVA or the EVA through sex change, as derived from the sex change EVA material of Shanghai Yi Ma encapsulant Co., Ltd.
As shown in Figure 1, different from existing glue spreading method, fabric 5 also passes through above-mentioned elastic supporter thing 2 after conveying cylinder 4.Fabric 5 contact resilient supporter 2 upper surfaces and scraper 1 are vertically placed on described fabric 5 silica gel 3 are carried out to blade coating.Elastic supporter can be the semicircle cylindricality shown in Fig. 1, but does not limit to therewith, as being elongated cuboid etc.
The silica gel of the coating substance using in the present invention for selling on market, the preferred scope of its viscosity is 15-100Pa.S.Viscosity is excessive or too smallly all can impact gluing, if viscosity is too little, gluing weight can reduce along with the reduction of viscosity, is difficult to obtain high glue-spread; If viscosity is too large, when gluing, resistance strengthens, and fold, lines etc. easily occur fabric.
For obtaining the uniform coating needing, gluing speed is preferably controlled between 10-30m/min.
The empty formula glue spreader of cutter in the application, for the present invention, refers to that glue spreader does not have the elastic supporter in the present invention below scraper.
