Abstract

The utility model discloses dot-glued polypropylene fiber cloth using hot melt glue, which comprises polypropylene fiber cloth, wherein a hot melt glue net or hot melt glue dots are glued on the polypropylene fiber cloth which can be glued with other cloth or materials by the hot melt glue net or the hot melt glue dots at a low temperature. The hot melt glue net or the hot melt glue dots on a release film can be switched onto the polypropylene fiber cloth at any time, while the hot melt glue net or the hot melt glue dots on the polypropylene fiber cloth can be stuck on the other materials at any time without the limitation of the shape and the variety of the materials, thereby saving labor, time and space. Because dotted or netty hot melt glue (such as PA, EVA) is glued on the polypropylene fiber cloth, the materials can ventilate after being glued. The hot melt glue is capable of keeping the hand feeling of the materials, resisting aging and keeping good type and has no pollution.

Description

PUR point bonded type Polypropylene

Technical field

The utility model relates to a kind of polypropylene fibre cloth, particularly a kind of PUR point bonded type Polypropylene.

Background technology

The coating processing method of traditional Polypropylene is that Polypropylene is directly heated and is coated with the laminating of heating of PUR or cementing on coating machine, and Polypropylene non-refractory will contraction distortion or change feel, outward appearance; Can only fit with staff cementing, but as long as glue laminating, just have pollution, and relatively lose time and account for place more, all these make us beating one's brains and helpless very much problem, have badly influenced the product competitiveness of enterprise and the ability of survival and development.

For the problems referred to above, the design people has developed a kind of PUR point bonded type Polypropylene, by low temperature shift formula PUR coating method, can in three seconds, point-like or weblike heat melten gel be transferred on required Polypropylene the soonest, can turn at any time, can paste at any time, be not subject to the restriction of material shape kind, saving of work and time save space.Due to what use, being the netted PUR of dot type (as PA, EVA), can breathing freely, can keep the feel, ageing-resistant of material after laminating, is free of contamination PUR.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of PUR point bonded type Polypropylene.

The utility model solves the technical scheme that its technical problem adopts:

PUR point bonded type Polypropylene, is characterized in that: comprise polypropylene fibre cloth, be bonded with PUR net or PUR point on polypropylene fibre cloth.

On described polypropylene fibre cloth, be bonded with the described PUR net or the PUR point that by mould release membrance or release liners low-temperature heat melting, shift.

The thickness of described PUR net is 0.1-5mm.

The number N of described PUR point is 100 of every square centimeter of 0 < N <.

The number N of described PUR point is 30 of every square centimeter of 5 < N <.

The temperature of described low-temperature heat melting is 100 ℃-120 ℃.

The beneficial effects of the utility model are: the utility model comprises polypropylene fibre cloth, on polypropylene fibre cloth, be bonded with PUR net or PUR point, polypropylene fibre cloth can be bonding with other cloth or material at low temperature by PUR net or PUR point, PUR net on mould release membrance or PUR point can forward on polypropylene fibre cloth at any time, and PUR net or PUR point on polypropylene fibre cloth can be affixed on other material at any time, be not subject to the restriction of material shape kind, saving of work and time save space, due to what bond on polypropylene fibre cloth, be that point-like or netted PUR are (as PA, EVA), after laminating, can breathe freely, can keep the feel of material, ageing-resistant, shape-retaining ability is good, it is free of contamination PUR.

Accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is the schematic diagram that is bonded with PUR point on polypropylene fibre cloth.

Fig. 2 is the schematic diagram that is bonded with PUR net on polypropylene fibre cloth.

The specific embodiment

See figures.1.and.2, the utility model discloses a kind of PUR point bonded type Polypropylene, comprise polypropylene fibre cloth 1, be bonded with the PUR net 3 or the PUR point 2 that by mould release membrance or release liners low-temperature heat melting, shift on polypropylene fibre cloth 1, the temperature of described low-temperature heat melting is 100 ℃-120 ℃.PUR is a kind of plastic adhesive, and in certain temperature range, its physical state changes with temperature change, and chemical characteristic is constant, and it has nonpoisonous and tasteless, and hardening time is fast, and adhesive strength is high, the advantage of environmental protection.

The thickness of PUR net 3 has a great impact for polypropylene fibre cloth 1 and the bonding of other material, the too thin meeting of PUR net 3 is pasted not strongly Polypropylene and other material, PUR net 3 is too thick makes the thickness after Polypropylene and other material are pasted obviously increase and harden, have a strong impact on profile and the feel of material, thereby the thickness of PUR net 3 is preferably 0.1-5mm, its preferred numerical value can be 1 mm or 0.5 mm.

The density of PUR point 2 has a great impact for polypropylene fibre cloth 1 and the bonding of other material, PUR is put the too little meeting of 2 density is pasted not strongly Polypropylene and other material, PUR is put 2 density can affect too greatly the gas permeability after bonding, thereby the number N of PUR point 2 is 100 of every square centimeter of 0 < N <, preferably the number N of PUR point 2 is 30 of every square centimeter of 5 < N <, certainly also has other preferred value, such as number N can be preferably 40, 50, 60, 70, 80, 90 etc.

A kind of PUR point bonded type Polypropylene above the utility model embodiment being provided, be described in detail, applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand method of the present utility model and core concept thereof; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.

Claims
