Problems solved by technology

However, the swimming cap often falls off during use, which brings inconvenience to swimmers.
Traditional plastic swimming caps are usually molded at one time by a vulcanization molding machine, so the fit between the edge of the rubber cap and the human head is not ideal. In addition, the lubricating effect of water makes the rubber cap easy to remove. swimmer's head comes off

Abstract

The invention discloses a process for preventing swimming rubber cap from falling off. The process comprises the following steps: S1, preparing a rubber raw material; S2, plasticating raw nitrile rubber, mixing a polyurethane elastomer and an epoxy resin with the raw nitrile rubber to obtain a mixture A; S3, sequentially adding polyethylene glycol, sodium polyacrylate, nano metals, carbendazim, vermiculite powder, a curing agent, an anti-aging agent, xanthan gum, a vulcanizing agent and an assistant vulcanizing agent into the mixture A, and mixing to obtain anti-shedding rubber; S4, fixing theswimming rubber cap on a sizing fixing seat, enabling the edge of the swimming rubber cap to be erected, wiping the edge clean, uniformly spreading the anti-shedding rubber, then drying at low temperature, carrying out vulcanization, and cooling to room temperature to complete the process for preventing the swimming rubber cap from falling off. The process for preventing the swimming rubber cap from falling off is simple to operate, low in requirements for equipment, simple and mild in technological conditions, and easy to implement; the treated swimming rubber cap does not easily fall off, and is long in service lift, good in elasticity and comfortable to wear.

Description

technical field [0001] The invention relates to the technical field of swimming rubber cap production, in particular to a technique for preventing the swimming rubber cap from falling off. Background technique [0002] Swimming rubber cap, referred to as swimming cap, is one of the basic equipment for swimming. Wearing a swimming cap while swimming can not only prevent ear shock, protect the head, but also prevent the hair from being completely soaked in chlorinated water, thereby protecting the hair, reducing the damage to the hair quality caused by the pool water, and reducing resistance, allowing swimming swimmers faster. However, the swimming cap often falls off during use, which brings inconvenience to swimmers. Traditional plastic swimming caps are usually molded at one time by a vulcanization molding machine, so the fit between the edge of the rubber cap and the human head is not ideal. In addition, the lubricating effect of water makes the rubber cap easy to remove...
