Local-reinforced apron rubber and its production

Abstract

A process for preparing the locally reinforced rubber apron includes such steps as proportioning the raw rubber materials pugging, putting the mixture on a fabric, calendering for attaching the rubber material onto the fabric, calendering for sticking the locally reinforcing rubber sheet, and sulfurizing.

Description

technical field [0001] The invention relates to a rubber apron design, in particular to a rubber apron with partial reinforcement and a method for producing the rubber apron. Background technique [0002] By the way, the common rubbers are rubber and plastic rubbers with uniform thickness. This type of rubber usually refers to a composite material of a layer of rubber and a layer of cloth, but for some specific purposes, such as gloves, aprons, work clothes, etc., then It is necessary to partially thicken the rubber to prolong the service life of the product and protect the safety of personnel in operation. [0003] Take industrial aprons as an example, most of them are used in slaughterhouse workers, fishmongers, porters and factory workers, etc. When industrial aprons are used, there are more opportunities to rub against the abdomen, and because of The chance of rubbing the abdomen of the apron during operation is greater than other parts, so that the whole apron is more ...

Problems solved by technology

[0003] Take industrial aprons as an example, most of them are used in slaughterhouse workers, fishmongers, porters and factory workers, etc. When industrial aprons are used, there are more opportunities to rub against the abdomen, and because of The chance of rubbing the abdomen of the apron during operation is greater than other parts, so that the whole apron is more likely to be damaged from the abdomen and be eliminated, thus reducing the service life of the apron

[0004] In order to improve such shortcomings, the industry has some reinforcement methods, such as sewing a piece of the same material on the abdomen of the apron to increase the thickness of the abdomen. The position of the needle hole in the car will cause stress concentration and cause damage

Another way of reinforcement is to use an adhesive to bond another piece of reinforcing material on the abdomen, but the adhesive is usually not resistant to oil and water, so the part where the reinforcing material is attached is easy to fall off

Furthermore, regardless of the sewing reinforcement or subsequent reinforcement, in addition to the above disadvantages, the production process is relatively complicated, which requires a lot of manpower and time, and the labor cost is relatively high.
