Problems solved by technology

At present, most of the butyl gloves on the market are unlined, and the lined ones are difficult to vulcanize due to the difficulty of vulcanization (the bond with the liner is not firm, and the rubber layer is easy to bulge and peel off), which makes its processing difficult, and the processing technology of different manufacturers has great differences. different
[0003] In addition, the film thickness of the lining is generally thicker, and dehydration is relatively difficult. In addition, butyl rubber itself is difficult to pre-vulcanize, and bubbling is more likely to occur in the later high-temperature treatment process.
The processing technology of the top-grade nylon lined gloves on the market is to use the mold to directly dip the glue, dry the film, then put on the nylon fiber gloves, and then dip the glue again, the process is very cumbersome

Abstract

The invention discloses a preparation method of lined double-layer butyl chemical protective gloves. The preparation method comprises the steps that the formula of a butyl rubber material is changed,and the butyl rubber material comprises, by mass, 90-120 parts of butyl rubber latex, 1-5 parts of a surfactant, 0.5-2 parts of a vulcanizing agent, 1-4 parts of an accelerant A, 1-4 parts of an accelerant B and 1-5 parts of an activator; and the process is optimized, low-temperature heat preservation pre-vulcanization is carried out when butyl rubber material is prepared, before formal impregnation, a thickening agent is added to achieve adjustment to prepare primary rubber with the viscosity of 1000-2100 mpa.s and secondary rubber with the viscosity of 2500-4000 mpa.s, glove blanks (cotton glove blanks) are subjected to impregnation of two times, rubber dripping and rubber homogenizing treatment, primary drying box heat drying is carried out after primary impregnation, after secondary impregnation, low-temperature vulcanization is carried out at first, then high-temperature and high-pressure vulcanization treatment is carried out, finally normal-pressure drying is carried out, and the lined double-layer butyl chemical protective gloves more excellent in gas defense performance, chemical prevention performance and air tightness are prepared.

Description

Technical field[0001]The invention relates to the production technology of labor protection protective gloves, in particular to a preparation method of a lining double-layer butyl chemical resistant gloves.Background technique[0002]Butyl rubber chemical resistant gloves are special-demand gloves, which are military products. They have excellent anti-toxic and chemical properties and good air tightness. The gloves are suitable for intermediate polar organic compounds, such as peroxides, strong acids, strong alkalis, and alcohols. , Aldehydes, ketones, ethers, etc., with good protective properties. At present, most of the butyl gloves on the market are unlined. For those with lining, the glue is difficult to vulcanize (the bond with the lining is not strong, and the glue layer is easy to bulge and peel off), which makes the processing technology difficult. The processing technology of different manufacturers is very different. different.[0003]In addition, the thickness of the lining f...
