Abstract
The invention discloses a kind of methods that argon medium Low Temperature Plasma Treating vulcanizate improves adhesive property, and method and step are：（1）Use argon gas for processing atmosphere, the Low Temperature Plasma Treating that pair 1142 vulcanizates carry out under conditions of vacuum degree is (40 ± 5) Pa；（2）Processing power is 120 ~ 160 W, 200 ~ 240 s of time；（3）After the processing of 1142 vulcanizates in 4 h, one layer of 2024 aluminum alloy plate materials film is bonded on 1142 vulcanizate surfaces using JQ-1 leakerna glues, vulcanizes 90 min or more after bonding under normal temperature environment, then press standard testing peel strength.The present invention makes the peel strength between 1142 vulcanizates and 2024 aluminum alloy plate materials be increased at least 300 N/m from 25N/m.
Description
Technical field
At a kind of method of 1142 vulcanizates of bonding more particularly to a kind of argon medium low temperature plasma
After managing 1142 vulcanizates, the method for improving its surface adhesive strength is realized.
Background technology
Natural rubber is the milk oozed out by rubber tree, by the solid being process such as condensing and drying, and it is very high
Elasticity.Rubber is mainly made of polyisoprene, molecular weight distribution between 10 ~ 1,800,000, be a kind of comprehensive performance very
Outstanding renewable natural resources.And wherein reach 98% or more along the content of 1,4- polyisoprene.The natural rubber of heat ageing
Glue shows as elastomer at normal temperatures, and surface is inert, should not be Nian Jie with other materials, the processing of generally use solvent, and big
The ageing-resistant service life of partial solvent treated sulfurized natural rubber can shorten.And low-temperature plasma treatment technology is a kind of exists
Under the premise of not reducing processed material physical and mechanical property.The surface wettability of difficult viscous high molecular material can be effectively improved and glued
Connect performance methodology.
This technology makes 1142 vulcanizates have good cementability.
