Abstract
The invention discloses a method of improving peeling strength of thermoplastic polyurethane elastomers and polyester fiber fabric; glue is coated between the thermoplastic polyurethane elastomers and the polyester fiber fabric, wherein the front and back sides of the polyester fiber fabric substrate are coated with the glue, subjected to thermal treatment for twice and then compounded with the thermoplastic polyurethane elastomers; the two thermal treatments comprise a first thermal treatment and a second thermal treatment; the first thermal treatment comprises the step of sending the glue-coated polyester fiber fabric substrate to a heating oven to dry, wherein the temperature on the surface of the fabric substrate is 160-180 degrees centigrade and the standing time in the oven is 1.5-2.5 min; the second heat treatment comprises the step of sending the baked polyester fiber fabric substrate again to an infrared oven, wherein the temperature on the front side is 110-120 degrees centigrade, the temperature on the back side is 100-110 degrees centigrade and the standing time in the oven is 1.5-3 min and then the fabric substrate subjected to the second thermal treatment of the oven is obtained. The purpose of improving the peeling strength of the hermoplastic polyurethane elastomers and polyester fiber fabric substrate can be realized by changing the conventional manufacturing process and without changing the traditional formula.
Description
Technical field
The present invention relates to the manufacturing technology field of Thermoplastic polyurethane elastomer material processing, especially a kind of method improving TPUE (TPU) and dacron fabric base material peel strength.
Background technology
Using dacron fabric as the strong material of bone, Thermoplastic polyurethane elastomer material as the fabrics for industrial use of surfacing, be widely used in must meet food-grade and require tobacco processing, food processing and military, the industries such as medical supplies.And adopted TPUE by increasing environment-friendly function macromolecule, in future, there is good development prospect.
But due to the problem such as polarity of Thermoplastic polyurethane elastomer material, add man-hour carrying out manufacture, the peel strength after Thermoplastic polyurethane elastomer material and dacron fabric base material bond will reach and specify certain difficulty.
Although employ thermosol in the mill, but thermosol cannot be achieved to the infiltration of fabric in normal processing and manufacturing, generally only can cover fabric face, is difficult to enter fabric, cause goods peel strength not reach the requirement of client, also have impact on the service life of its finished product.
Summary of the invention
The object of the invention is: provide a kind of method improving TPUE and dacron fabric base material peel strength.
The object of the invention is achieved through the following technical solutions: a kind of method improving TPUE and dacron fabric peel strength, glue coated between TPUE and dacron fabric, then, first glue is coated on dacron fabric base material positive and negative, then after secondary heat treatment with TPUE compound, wherein secondary heat treatment is:
First time heat treatment is: the dacron fabric base material of coated glue is sent into heated oven and dries, fabric substrate surface temperature is 160 DEG C ~ 180 DEG C, the time of staying 1.5 ~ 2.5min in baking oven;
Second time heat treatment is: the dacron fabric base material dried is sent into IR bake again, its positive surface temperature is 110 DEG C ~ 120 DEG C, reverse side temperature is 100 DEG C ~ 110 DEG C, and in baking oven, the time of staying is 1.5--3min, obtains the heat treated fabric substrate of secondary baking oven.
On such scheme basis, the present invention includes following concrete steps:
The first step: use coating equipment that above-mentioned glue is coated on dacron fabric base material positive and negative, coated weight is 80-150g/ ㎡;
Second step: the dacron fabric base material of coated glue is sent into heated oven and dries, fabric substrate surface temperature is 160 DEG C ~ 180 DEG C, the time of staying 1.5-2.5min in baking oven;
3rd step: the dacron fabric base material dried is sent into IR bake again, its positive surface temperature is 110 DEG C ~ 120 DEG C, and reverse side temperature is 100 DEG C ~ 110 DEG C, and in baking oven, the time of staying is 1.5--3min, obtains the heat treated fabric substrate of secondary baking oven;
4th step: TPUE layer and the heat treated fabric substrate of secondary baking oven are carried out compound.
Superiority of the present invention is: by changing conventional manufacturing process, when not changing conventional formulation, can realize the object improving TPUE and dacron fabric base material peel strength.
Detailed description of the invention
Improve a method for TPUE and dacron fabric base material peel strength, comprise the steps:
The first step: by recipe requirements configuration glue;
Second step: use coating equipment glue to be coated on dacron fabric base material positive and negative, coated weight is 80-150g/ ㎡;
3rd step: the dacron fabric base material of coated glue is sent into heated oven and dries, fabric substrate surface temperature is 160 DEG C ~ 180 DEG C, the time of staying 1.5-2.5min in baking oven;
4th step: by dried dacron fabric base material send into IR bake again and carry out glue activation, its positive surface temperature is 110 DEG C ~ 120 DEG C, and reverse side temperature is 100 DEG C ~ 110 DEG C, and in baking oven, the time of staying is 1.5--3min;
5th step: the fabric substrate using suitable process equipment TPU coating and secondary to be entered baking oven carries out compound.
Beneficial effect of the present invention:
1, after the dacron fabric base material secondary of glue coated enters baking oven, improve the stripping performance of TPU coating and fabric substrate, peel strength test is in table 1;
2, follow-up processing temperature can suitably reduce, and improves production security.
