Abstract
The present invention belongs to the field of reflective fabric production method, and its preparation method includes the following steps: a). applying adhesive on polyester film, drying and combining it with polyethylene film; b).preheating the above-mentioned composite film and spreading glass microbeads on said composite film, then more heating to make the glass microbeads be adhered to the thermoplastic polyethylene; c). Making aluminum be deposited on the above-mentioned glass microbeads; d). Applying adhesive on the above-mentioned aluminized glass microbead film, drying and combining it with fabric; e). Stripping the aluminized film from the above-mentioned fabric layer so as to obtain the invented silver color reflective fabric.
Description
Technical field
The invention belongs to the method field of manufacturing of reflective cloth.
Background technology
Retroreflecting is a kind of optical phenomena, shines when light on the object of lens and so on, focuses on after reflecting, and returns light source direction through the lens refraction again from the focus reflection again, Here it is retroreflecting.Reflective cloth has the incident light that will shine on it and reflects by the primary source direction, improve the function of self visibility, thereby be made into clothes or other articles for use, and can strengthen pedestrian or object in the night of bad visibility or the security in the dark surrounds, prevent the generation of unexpected traffic accident.
Release reflective cloth product from the sixties abroad, and enter Chinese market from the eighties.Domesticly begin development from the mid-80, and in having, the reflective cloth product of low-grade grey comes out.High-grade silvery reflection cloths produce market is an external product then always, and particularly Minnesota Mining and Manufacturing Company's product monopolizes, and its expensive price makes the domestic user be difficult to bear.。
The technology of the reflective cloth of existing manufacturing has following several:
1. the reflective cloth of low-grade grey chromogen: fabric → gluing → preliminary drying → plant → drying → batch.
This method has following characteristics:
1) fabric face need pass through special treatment.
2) gluing thickness requirement height, gluing has approached, and has influence on the bonding fastness of fabric and glass microballoon; Gluing is thick, then makes the focal position inaccurate, influences intensity of light reflection.
3) face sense: grey is more coarse.
4) intensity of light reflection:＜100cd/lx.m
2(5 ° of incidence angles, viewing angle 12 ').
2. the reflective cloth of middle-grade grey:
A. polyester film → gluing → drying → plant → batch;
B. aluminize;
C. antiadhesion barrier → gluing → drying → with B compound → batch;
D. fabric → gluing → drying → with C compound → batch.
This method has following characteristics:
1) fabric face need pass through special treatment.
2) plant gluing thickness requirement height, gluing has approached, and has influence on the bonding fastness of polyester film and glass microballoon; Gluing is thick, and the compound ball after then aluminizing can't carry out.
3) compound ball gluing thickness requirement height, gluing has approached, and has influence on the bonding fastness of fabric and glass microballoon; Gluing is thick, then makes the focal position inaccurate, influences intensity of light reflection, and face sense is simultaneously grown dim.
4) face sense: grey.
5) intensity of light reflection: 350～400cd/lx.m
2(5 ° of incidence angles, viewing angle 12 ').
Comprehensive above-mentioned two kinds of processes, can see:
(1) the reflective cloth outward appearance of prior art for preparing is grey, can not satisfy domestic and international client simultaneously to dress ornament safety, requirement attractive in appearance.
(2) gluing required precision height is made troubles to production operation, causes the instability of product quality easily.
(3) fabric face need pass through special treatment, and the cost of product is increased.
(4) intensity of light reflection can not satisfy the higher level requirement of client.
Summary of the invention
Purpose of the present invention just provides a kind of preparation method of advantages of simplicity and high efficiency silvery reflection cloths, and Zhi Bei reflective cloth quality and outward appearance is all fine in this way.
In order to achieve the above object, make reflective cloth surface be silver color, must make aluminium coated become a reflecting layer continuously, and to make aluminium coated become a reflecting layer continuously, then must directly on aluminium coated, be coated with compound, and will satisfy is nonpolar being coated with compound plant film on the aluminium coated under the normal temperature state directly, and hot melt character is arranged under heating state, just can satisfy the needs of plant.
According to above-mentioned requirements, selecting low density polyethylene (LDPE) is the plant film.Low density polyethylene (LDPE) is the easy contraction distortion of film under heating state, and rule of thumb, we adopt with the polyester film technology compound with it and solve.
The concrete preparation method's step of silvery reflection cloths of the present invention is as follows:
A, on polyester film gluing, dry back is compound with polyethylene film;
B, will spill glass microballoon after the above-mentioned composite membrane preheating, and then heating, make the thermoplastic polyethylene cling glass microballoon;
C, with aluminium-vapour deposition on above-mentioned glass microballoon;
D, on above-mentioned aluminum plating glass microballon film gluing, dry back is compound with fabric;
E, the aluminizer on the above-mentioned fabrics layer is peeled off, silvery reflection cloths.
Beneficial effect of the present invention:
1) the reflective cloth with method preparation of the present invention is silver color, and the surface is fine and smooth, and outward appearance has satisfied client's needs.
2) owing to adopt thermoplastic polyethylene's composite membrane technology plant, density improves, and intensity of light reflection reaches 450～500cd/lx.m
2(5 ° of incidence angles, viewing angle 12 ') improved about 20% than original technology.
3) fabric face only needs general the processing, and compound need two procedures of former ball, and the existing one procedure that only needs has been simplified production technology, and production efficiency is improved.
4) because of the thickness of low density polyethylene films is certain, the plant condition is certain, it is nonpolar that the surface is, avoided because of gluing thick cause the ball difficulty or influence the problem of intensity of light reflection, constant product quality, qualification rate has improved 3%, has saved raw material.
5) in the middle of the product of identical performance, the unit materials cost is by 23 yuan/m
2Drop to 20 yuan/m
2
To sum up, with the silvery reflection cloths of method preparation of the present invention, because of simple process, the stabilized quality of its original creation, moderate price will be subjected to user's extensive welcome.
Description of drawings
Fig. 1 is the structure chart of reflective cloth.Wherein 1 is glass microballoon, the 2nd, and binding agent, the 3rd, reflecting layer, the 4th, fabric base cloth.
The specific embodiment
The concrete preparation method's step of silvery reflection cloths of the present invention is as follows:
A, be coated with polyurethane composite gel on polyester film, dry back is compound with low density polyethylene films;
B, the preheating in 140 ℃ of preheating cabinets of above-mentioned composite membrane is spilt glass microballoon after 15 seconds, and then enter in 170 ℃ of drying tunnels 45 seconds of heating, make the thermoplastic polyethylene cling glass microballoon;
