Through the technical scheme, the invention has the beneficial effects that: the waterproof membrane manufactured by the manufacturing method of the high-temperature-resistant waterproof membrane can be ironed at the high temperature of 200 ℃ without foaming and peeling.
Detailed Description
The present invention is further illustrated by the following examples.
The high-temperature-resistant waterproof film is prepared from the following substances: the polyurethane resin, butanone, toner, polyisocyanate resin and wear-resisting agent are mixed according to the following weight ratio: 1: 0.4: (0.018-0.03): (0.01-0.05): (0.01-0.05). Wherein the wear-resisting agent is block copolymer of polyethylene oxide, ethylene oxide and propylene oxide.
The manufacturing method of the high-temperature-resistant waterproof film comprises the following steps:
manufacturing a high-temperature-resistant waterproof film matrix: mixing the components in a weight ratio of 1: 0.4: (0.018-0.03): (0.01-0.05): (0.01-0.05) polyurethane resin (6158A glue), butanone (solvent), toner, polyisocyanate resin (curing agent) and wear-resisting agent (high-molecular active agent) are mixed and stirred uniformly, and then the mixture is placed for half an hour to break bubbles generated in the stirring process, and then coating is carried out to prepare the membrane. Wherein the wear-resisting agent is a high-molecular active agent and is a block copolymer of polyethylene oxide, ethylene oxide and propylene oxide. The polyisocyanate resin is a curing agent. In this example, the coating thickness was (0.024-0.042) mm. In the embodiment, the zipper cloth is coated on a coating machine, the coating tension of the coating machine is (10-30) N, the coating speed is (6-10) m/s, the coating wind degree is 20m/s, the temperature of an oven of the coating machine is gradually increased from low to high within the range of (45-90) DEG C during baking, the baking temperature of the last oven is reduced to 80 ℃, and the baking time of each oven is (10-15) s. When baking, the temperature is gradually increased to prevent the air bubbles from being generated due to too large temperature change, the temperature of the last section of oven is reduced to 80 ℃, and the temperature is prevented from being too high when the oven is taken out. In this example, the coater was a coater produced by the wenzhou borry machine factory.
The waterproof film is divided into a common waterproof film and a leather waterproof film according to the coating thickness, and the common waterproof film and the leather waterproof film are taken as examples, and the setting parameters of the coating machine are as follows:
the baking time of the common waterproof film in each section of the oven is 10s, and the baking time of the leather-feeling waterproof film in each section of the oven is 15 s.
In specific implementation, different formulas of the waterproof membrane are in the following relationship with high temperature resistance:
in the following examples, 1kg of polyamino potassium acid ester resin (6158A glue) is used as a quantitative ratio.
The first embodiment is as follows:
the examples are the results of tests without addition of curing agent and anti-abrasion agent, and the waterproof film is easily foamed, deformed and damaged during ironing.
Example two:
in the second embodiment, the wear-resistant agent which is equivalent to 5 percent of the polyurethane resin is added into the formula, so that the release force and the temperature resistance are improved, and the effect of high-temperature ironing cannot be achieved.
EXAMPLE III
In the third embodiment, a curing agent with an equivalent weight of 5% of that of the polyurethane resin is added on the basis of the second embodiment, and after film formation, the common waterproof film and the film forming paper can not fall off and can not detect the release force and resist temperature; the temperature resistance of the leather-feeling waterproof film can reach the ironing temperature, but the release force is too large, so that the subsequent film sticking production is not facilitated.
Example four
In the fourth embodiment, a curing agent and an anti-wear agent which are equivalent to 1% of the polyamino potassium acid ester resin are added, the temperature resistance after film forming meets the ironing requirement, and the release force is also in the range.
Many other embodiments are not listed, but only four of them are selected, and the most suitable process is the fourth embodiment.
The waterproof film manufactured by the manufacturing method of the high-temperature-resistant waterproof film can be ironed at the high temperature of 200 ℃ without bubbling and peeling, is applied to the zipper, solves the problems of bubbling, peeling and the like of the waterproof zipper in the ironing process, can meet the performance requirements of the zipper in all aspects, has wide market prospect, and meets the development and environmental protection requirements of the zipper industry.
While the present invention has been described in detail with reference to the specific embodiments thereof, it should not be construed as limiting the scope of the invention. Various modifications and changes may be made by those skilled in the art without inventive step within the scope of the present invention as described in the appended claims.
