[0073] A method for preparing a solidified latex includes the following steps:

[0074] S01: Mix the raw material latex and the dispersion, stir and foam to obtain a latex foam;

[0075] S02: spray latex foam on the carrier;

[0076] S03: Add a gelling agent to the latex foam sprayed on the carrier, and then keep it at a temperature of 65-75°C for 5-15 minutes to obtain a cured latex.

[0077] A solidified latex prepared by the above method.

[0078] In one embodiment, the above-mentioned cured latex is used in precision foamed latex products.

[0079] In one embodiment, the foamed latex precision products in the present invention include impregnated products, sponge products, woven products and the like.

[0080] The latex cured product can be used to obtain the foamed latex precision product through conventional molding and thermal vulcanization processes.

[0081] The molding may adopt a compression molding method. The pressure of the molding press used for the compression molding may ...

Embodiment 1

[0152] A method for preparing an edge-pressed latex mold cup includes the following steps:

[0153] S01: Mix the raw material latex and the dispersion, and foam at 900r / min for mechanical stirring for 10 minutes to obtain a latex foam;

[0154] S02: spray latex foam on the carrier;

[0155] S03: Add a gelling agent to the latex foam sprayed on the carrier, and then keep the temperature at 70°C for 10 minutes to prepare a latex cured product;

[0156] S04: Transfer the cured latex to the mold cup of the vulcanizer;

[0157] S05: The curing press is heated and pressurized to press, shape and vulcanize the cured latex;

[0158] S06: Hot water leaching and drying.

[0159] In the step S01, the raw material latex is natural rubber.

Abstract

The invention discloses a preparation method of latex condensate, an edge pressing latex mold cup, a preparation method and application. The preparation method of the edge pressing latex mold cup comprises the steps that the latex condensate is transferred to a mold cup mold of a vulcanizing machine; the vulcanizing machine is heated and pressurized to conduct edge pressing, shaping and vulcanizing on the latex condensate; and hot water leaching and drying are carried out. According to the edge pressing latex mold cup, a whole-health auxiliary agent is adopted, toxic substances such as sodium fluorosilicate are avoided, a product is healthier, more suitable for skin use and is especially suitable for female tender chest skin, the high plastic deformation retention rate is achieved, and elasticity, strength and the like are very good; secondly, a new process method is created, latex foaming sponge with different densities is produced in the same latex foaming materialogy, use is not limited to the underwear industry, and more foaming products can be made easier to process because of the process.

Description

Technical field [0001] The invention relates to the technical field of women's bra mold cups and latex, in particular to a preparation method of a latex solidified product, a side-pressing latex mold cup, a preparation method and an application. Background technique [0002] In recent years, bras that use latex to prepare mold cups are developing rapidly. However, the bra prepared by processing the mold cup with latex is limited by the process. The manufacturing techniques of latex pillows and mattresses are still being used. This process uses the Dunlop process: first pour the foamed mature latex into the mold cavity, vulcanize it into a latex mold cup, and trim it for use. [0003] The main reasons why the latex mold cup prepared by Dunlop process cannot be applied on a large scale in the underwear industry are as follows: [0004] The overall density of the mold cup is the same. If the prepared mold cup is very thin, then the overall edge of the mold cup is particularly thin. ...
