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

example 1

[0046] Example 1: General single-layer apron rubber

[0047] 100 parts by weight of polypropylene-butadiene rubber (PHR), internal and external lubricant 1.0PHR, calcium carbonate 40PHR, plasticizer 10.0PHR and other compositions are carried out in a 10,000-horsepower mixing device to mix uniformly; The compounded rubber is transported to the first rolling machine (setting temperature 70-80°C), and mixed with vulcanization accelerator 1.9PHR and bridging agent 1.8PHR; then the rubber is transported to the second Fully knead in two rolling mills (setting temperature 80-90°C); then send the uniformly mixed rubber to the calender to be rolled into the required thickness, and the temperature of the calender is set at 90-110°C; After the rubber material is calendered, the rubber flakes are drawn out with polyester-nylon blended gauze (fabric) as the carrier. The thickness of the rubber flakes is set at 0.38mm and the width is 54 inches; Sulfur, the temperature is set at 130-150°C ...

example 2

[0050] Example 2: Abdominal reinforcement apron rubber

[0051] Using the same rubber compound as in Example 1, carry out the second calendering process before adding vulcanization. During the first calendering, the thickness of the rubber sheet is set at 0.38 mm and the width is 54 inches. After the rubber sheet is wound up, Then carry out the second calendering procedure, the thickness of the rubber sheet (reinforcing rubber) is set at 0.20mm, and the width of the glue is 14in; then all the rubber sheets are sent to the vulcanizing device for vulcanization, and the temperature is set at 130~ 150°C 2 , and the time is 15 minutes. After the vulcanization is completed, the rubber apron rubber for abdominal reinforcement can be obtained.

[0052] The abdomen reinforcing apron rubber that is made above is carried out physical property test, and its test result is shown in Table 2.

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 ...
