Problems solved by technology

[0003] Existing nitrile gloves and latex gloves are widely used in industries such as petrochemical industry, paint printing, agriculture and animal husbandry, and automobile machinery maintenance; When it is used for work in contact with liquids, because the rubber surface is too smooth, there are defects such as low friction, insufficient grip, stiff use, etc., and when the palm is sweaty and airtight when used for a long time, the user feels uncomfortable during use.
Because latex is characterized by softness and wear resistance, it has a wide range of applications, but in terms of the rubber content used for dipping gloves, the latex gloves are very hard to wear due to the addition of calcium carbonate, and the use of gloves is not dexterous and comfortable.
Such as Chinese patent publication number is CN1596786A, discloses a kind of manufacture method of nano-calcium carbonate latex gloves, and it adds and disperses a certain amount of nano-calcium carbonate together with conventional ingredients together in natural latex, and then dips and makes by conventional molding process. Latex gloves containing nano-calcium carbonate are made into latex gloves, and then the finished product is obtained through the processes of flipping, chlorination, foam washing, rinsing, and drying. The active interaction force between nano-calcium carbonate and the polymer makes the polymer particles more tightly packed , but in the process of use, its softness decreases and there is rigidity

Abstract

The invention relates to a preparation method of a one-pass foaming two-pass frosted surface glove. The preparation method comprises the following steps of S1, sleeving the glove blank on the hand mold, preheating the hand mold and soaking the coagulator, dipping the first impregnating adhesive and then dipping the coagulating agent, and then dipping the second impregnating adhesive, wherein the first impregnating adhesive is a foaming adhesive added with a physical foaming agent, and the second impregnating adhesive contains a surfactant; S2, spraying frosted particles; S3, pre-drying; S4, washing the glove with water; and S5, vulcanizing to obtain a one-pass foamed two-pass frosted surface glove. The glove prepared by the method is light, sensitive, soft and comfortable, provides good protection, and has the advantages of being breathable, excellent in grabbing force and the like, the safety of a user in the working process can be better protected.

Description

technical field [0001] The invention relates to a method for preparing gloves with a frosted surface foamed once and twice, and belongs to the technical field of labor protection products. Background technique [0002] Make gloves with cloth or yarn, soak the gloves in the prepared glue (such as nitrile, natural latex, etc.) for a moment, take them out and dry them to form rubber gloves, also known as dipped gloves , Hanging gloves, rubber gloves. [0003] Existing nitrile gloves and latex gloves are widely used in industries such as petrochemical industry, paint printing, agriculture and animal husbandry, and automobile machinery maintenance; When it is used for work in contact with liquids, because the rubber surface is too smooth, there are defects such as low friction, insufficient grip, stiff use, etc., and when the palm is sweaty and airtight when used for a long time, the user feels uncomfortable during use. . Because the characteristics of latex are soft and wear-...
