Problems solved by technology

[0003] In view of the problems raised by the background technology, the purpose of the present invention is to propose a method for preparing soft latex stickers. The preparation method is simple and the processing efficiency is high. The side of the latex sticker that contacts the human body can be made sticky without applying glue, and solves the problem In the preparation process of nipple stickers, glue needs to be brushed to provide stickiness for the nipple stickers, the preparation process is complicated, and the production efficiency is low;
[0004] Another object of the present invention is to propose using the soft latex patch prepared by the preparation method of the soft latex patch, which can be firmly pasted on the user's skin without sticking to the clothing and has good flexibility. High use comfort, which solves the problems of poor softness and poor use comfort of existing nipples

Abstract

The invention relates to the technical field of high polymer materials, in particular to a flexible glue breast patch and a preparation method thereof. The preparation method of the flexible glue breast patch comprises a step a of preparing a component A and a component B: step a1, well mixing 71-95 parts by weight of polyether polyol, 10-30 parts by weight of a plasticizer and 0.1-0.3 parts by weight of a catalyst to obtain the component A; and a2, well mixing 30-60 parts by weight of an isocyanate prepolymer and 50-70 parts by weight of a plasticizer to obtain the component B. The preparation method of the flexible glue breast patch is simple and high in processing efficiency. The problem that an existing breast patch is complex in preparation process and low in production efficiency is solved. The prepared flexible glue breast patch can be firmly attached to the skin of a user, cannot be attached to clothes, and is good in softness and high in use comfort level. The problem that an existing breast patch is poor in softness and poor in use comfort degree is solved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a soft latex sticker and a preparation method thereof. Background technique [0002] Breast stickers can protect breasts and improve the appearance of breasts. They are convenient to use and have an invisible effect, and are more and more favored by consumers. At present, nipple stickers are usually paste-type nipple stickers. In the process of manufacturing nipple stickers, it is usually necessary to apply glue on the surface of the nipple sticker body to form an adhesive layer. Fitting, the material of this nipple is hard, and the use comfort is low, and since it is necessary to apply glue on the surface of the nipple body to provide stickiness for the nipple, the preparation process is complicated and the production efficiency is low. Contents of the invention [0003] In view of the problems raised by the background technology, the purpose of the present inventio...
