Description

The on-slip skin

The utility model relates to a kind of on-slip skin, particularly relates to a kind ofly having good anti-slip effect, and has the on-slip skin that prevents the low temperature brittleness effect.

Press, at present on the market as gloves, anti-skidding mat ... Deng product, because of the consciousness raising of people's protection safety, so the demand of product and device quality also promote with it with on-slip function.And generally make the employed on-slip skin of aforementioned on-slip product on the market, be one deck nylon cloth, flannelette ... lay the on-slip layer that one deck has anti-slip effect Deng on the base cloth that constitutes of weaving cotton cloth, on-slip layer major part is made with the material of PVC (polyvinyl chloride); And the manufacture method of on-slip skin is the PVC of fusion to be added plasticizer (DOP) Hou be tiled in equably on the base cloth, imposes dry the processing again, can make that PVC on-slip layer is fixed to be covered on the base cloth, and becomes the on-slip skin of the good anti-slip effect of tool; Yet, use the made product of above-mentioned on-slip skin when low temperature or use when refrigerant latitudes,, and make the phenomenon of on-slip layer generation embrittlement often because of the embrittlement at low temperatures of PVC material, therefore the on-slip skin is not useful in the environment of climate of frigid zone, so its scope of application is narrower; Again, be easy to process the plasticizer that is added, when day, the Hou product contacted with human body skin, will produce harmful effect health for making PVC; And this type of consumable products is because of the waste recovery difficulty, so can cause the public hazards of environment when product forms discarded object.PVC no doubt has above-mentioned shortcoming, only has good anti-slip effect because of it, be easy to again make, so industry is still generally produced.In view of aforementioned on-slip instrument in the past, still have its desirable not to the utmost place, so that when using, can produce awkward shortcoming.Simultaneously, the recycling of rubber scrap also is a difficult problem at present, especially a large amount of waste materials that produced on the rubber industry production line, as foamed rubber on the residual limit of tailoring finished product Hou institute residue, the rubber finished product is handled bits material or the residual limit that Hou produced in processing ... Deng, or the rubber finished product of use each side in daily life, as tire, sole, diving suit, conveyer belt ... Deng, it not only forms trouble on waste disposal, take up space, more can increase manufacturing cost on foot virtually, therefore, if recovery that can these rubber scraps are in addition appropriate utilization, the new purposes effect of this rubber scrap of annotating separately, so can solve the problem that rubber scrap is handled, and can reduce cost and cut the waste, to bring rubber industry new opportunity.

Main purpose of the present utility model promptly is to provide a kind of on-slip skin that has good anti-slip effect and can prevent low temperature brittleness.

Another purpose of the present utility model is to provide a kind of on-slip skin, and it is to reach under the prerequisite of identical anti-slip effect, can fill part and utilize rubber scrap to save resource and to reduce cost.

For reaching above-mentioned purpose, the utility model is taked following technical scheme:

Be coated with the on-slip layer that one deck is mixed by PU resin (polyurethane) and rubber particles on a base cloth layer, rubber particles is below 30 orders,, it also utilizes the PU resin bonded on base cloth.

This layer base cloth is the cloth sheet fabric that is made of synthetic fibers; Rubber particles on this base cloth is the rubber scrap particle.

The utility model on-slip layer is through being ground into to the graininess below the 30MESH with the dry Hou of sizing material, and Hou interpolation solvent gives moistening, to finish moistening rubber particles more evenly blends in the PU resin, and the mixture of fusion Hou is coated on the base cloth, become to anchor at on-slip layer structure on the base cloth through super-dry Hou.

Owing to take technique scheme, make that the rubber particles in the on-slip layer has good on-slip effect, can prevent low temperature brittleness, and can fill part and utilize rubber scrap to save resource and to reduce cost.

Below by most preferred embodiment and accompanying drawing the utility model is elaborated:

Fig. 1 is the structural representation of the utility model one preferred embodiment.

Seeing also shown in Figure 1ly, is the on-slip skin of the utility model preferred embodiment, and it includes: base cloth layer 1 and on-slip layer 2; Wherein:

Therefore base cloth layer 1 is one deck cloth sheet fabric that is made of synthetic fibers substantially, and interweaving between the yarn of base cloth 1 and yarn is formed with hole 10.

On-slip layer 2, be to be laid on the base cloth 1, be to mix with predetermined ratio by PU resin (poly-system) 20 and the following rubber scrap particle 21 of 30MESH to constitute, when on-slip layer 2 is laid on the base cloth layer 1 under liquid state, partly the PU resin 20 near base cloth 1 will be infiltrated in the base cloth 1 by the hole 10 of knitting of base cloth 1, and hand over embedding to combine closely with base cloth 1 formation, rubber scrap particle 21 is the recyclable waste material that is produced on production line in addition, and it is preferable as the wearability of the vulcanie of tire etc., so being applied in, the on-slip micromicro that its Hou is constituted needs on the good product of wearability, and better as the on-slip of the soft rubber of diving suit etc., so the made on-slip micromicro of its Hou is applied in and needs on the good product of on-slip.

For can clearer this on-slip of understanding instrument, the fabrication schedule with present embodiment on-slip skin be summarized as follows now:

1. pulverize:

The rubber scrap that reclaims is classified according to color, proportion, situation such as dirty, and with the rubber scrap drying to reduce water content wherein, the particle assembly takes place when avoiding pulverizing to obtain required particle diameter, and the rubber scrap that Hou will be handled is pulverized with pulverizer.

2. moistening:

With pulverize rubber scrap particle 21 apparent gravities that Hou finishes add solvent give moistening, the computational methods of amount of solvent:

PU resin proportion ÷ rubber scrap proportion * rubber scrap weight * 0.8

3. fusion:

Be added in the PU resin 20 finishing the ratio of moistening rubber scrap particle 21 according to weight ratio (moistening rubber scrap particle/PU resin) 10%～100%, the color of looking required finished product again adds an amount of pigment, and even with the mixer dispersed with stirring.In this stage, rubber particles will fill part with the PU resin and merge equably.

4. coating:

The PU resin 20 and the rubber scrap particle 21 of fusion Hou are coated on the base cloth 1 equably with coating apparatus, and its coating speed need be decided on coating thickness and baking temperature.

5. dry:

It is the transitivity attractive in appearance that is related to product surface that baking temperature is set, therefore the front-end temperature setting should be a little less than solvent boiling point, so that filling part, the PU resin infiltrates in the lyriform pore 10 of weaving cotton cloth in the hope of filling a part gummed, and the setting of Hou section temperature should be higher than solvent boiling point about 30%, guaranteeing that solvent evaporates fully and quickens 20 maturations of PU resin, and make PU resin 20 and rubber grain produce pull-out capacity.

From the above, on-slip layer 2 of the present utility model is that utilization PU resin 20 is as intermediary's base material, be bonded to and make the skin cloth that is integral curing on the base cloth evenly coating rubber particles gluing on the base cloth, and utilization PU resin 20 adds rubber particles formed " epithelium " provides required anti-slip effect, wherein, PU resin 20 can use when low temperature and can not produce fragmentation, so the scope of application of its product is wider; Again, the rubber scrap particle 21 of fusion tool predetermined particle diameter in PU resin 20, to increase the on-slip of on-slip layer 2, and rubber scrap particle 21 is the rubber products that reclaim from discarded, therefore, not only can reduce manufacturing cost, but more rubber scrap is reclaimed in environmental protection, utilize on the earth limited resources and reduce environmental pollution with appropriate; So the utlity model has the practicality on the industry.
