Waterproof and moisture-permeable multifunctional polyurethane thin film glove

Abstract

A waterproof and moisture-permeable multifunctional polyurethane thin film glove at least comprises a glove body. The glove body is made of polyurethane raw materials containing polyethylene glycol structures in an integral forming mode; by utilizing the polyethylene glycol structures contained in the polyurethane glove body, the glove body can actually achieve the effects of preventing infiltration of liquid water, water vapor permeability, anti-solvent property and the like; and the glove body has the multifunctional effects of high elasticity, high strength, antibacterial property, antistatic electricity, color matching and the like by being supplemented with additives made of other polyurethane materials. In addition, according to the waterproof and moisture-permeable multifunctional polyurethane thin film glove, by utilizing a mold provided with the atomized surface and an impregnation technology, the finished thin film glove is easily demoulded, and the dry and comfortable feeling during wearing is achieved.

Description

technical field [0001] The invention is a polyurethane elastomer film composition; especially a polyurethane material with waterproof, moisture-permeable, antibacterial and antistatic properties, which is released by a special solvent, so that molds of various film sets can be immersed in the polyurethane release solution Make it evenly cover the surface of the mold, and then go through the drying process to make a waterproof and moisture-permeable multi-functional polyurethane film cover for the film cover. Background technique [0002] At present, a large number of film covers are used in the market, such as latex film covers used by medical staff for barrier and protection; anti-fouling and waterproof latex film covers for industrial use; latex film covers generally used for cleaning; or various rubber Film sets, etc. Because the moisture permeability of these known latex or rubber film sleeves is very poor, when the user wears these latex films for a period of time, the...

Problems solved by technology

[0005] However, after actually testing the manufacturing method of the waterproof and moisture-permeable cover, the inventor of the present case found that the waterproof and moisture-permeable cover made of this method and material is too thick, poor in elasticity and insufficient in strength, and it will collapse when pulled a little. break, and its thickness will also lead to unsatisfactory moisture permeability of the gloves, so it is a failed polyurethane (PU) film sleeve, and no one has developed waterproof, high elasticity, Multi-functional polyurethane (PU) film cover with high strength and high moisture permeability

[0006] Therefore, there are currently three types of PU gloves on the market. The first is to impregnate ordinary cloth gloves with PU to form a composite glove covered with PU. The disadvantage is that it is too thick and has no elasticity. , so the use is limited and cannot be used as a film cover; the second is to press and form a PU flat film in advance, then cut the PU flat film, and use the high-frequency hot pressing method to bond the cut PU film with other The disadvantages of sticking the cloth into a glove are high processing cost, poor structural strength, inconsistent elasticity, very ugly appearance, not environmentally friendly, inconsistent feeling when wearing, sticky and uncomfortable, and only some parts have the characteristics of PU material; the third One is to glue two pieces of cut PU flat film into a PU glove by high-frequency hot pressing method. The disadvantages are high processing cost, poor structural strength, and it is not ergonomic and sticky when worn.

Therefore, these non-integrated composite PU gloves have poor practicability, low consumer acceptance, high manufacturing costs, and no economic benefits
