Abstract
The invention discloses a kind of full-bodied tire air-tight layer rubber material composition, this sizing composition comprises brominated butyl rubber, 1742 butyl rubbers, carbon black N660, diatomite, magnesium oxide, stearic acid, 4m2 zinc oxide, 2 resins, naphthenic oil, altax, 7020 sulphur.In air/tight layer rubber feed composition, add diatomite, overcome easy fracture when original air retaining wall rolls, the defect of viscosity difference during shaping laminating, viscosity has increased significantly, and viscosity time shaping between air retaining wall and rim of the mouth sizing material is obviously improved.
Description
Technical field
The present invention relates to a kind of tire air-tight layer rubber material, be specifically related to a kind of full-bodied tire air-tight layer rubber material composition.
Background technology
Along with the continuous enhancing of national economic strength, automobile industry obtains swift and violent development, and automobile has become people and to have lived the requisite important vehicles, and car industry must develop the technological innovation and progress that have directly promoted tyre industry.Recently, because society is to the tight demand of the low oil consumption of automobile, devise the tire of a kind of lower calorific value and lighter in weight, and in tyre element, also the air retaining wall had compared with light weight being positioned at inside tires is applied, it has the function of the amount that less air is revealed by pneumatic tyre interior, improve resistance to air loss, mainly through using the rubber combination comprising isoprene-isobutylene rubber and elastoprene to improve resistance to air loss at air retaining wall, but easy fracture when current air retaining wall rubber combination rolls, during shaping laminating, viscosity is poor.
Diatomite is a kind of siliceous rock, and be a kind of biogenic silicastone, it formed primarily of the remains of diatom in ancient times.Its chemical composition is with SiO
2be main, there is a large amount of micropore, non-crystal structure.In Europe, diatomite uses as mineral wealth has had the history of more than 100 year, at first for assimilating glycerine, after 20th century, due to the development of industrial technology, product is throughout every field such as environment, building, agricultural, industry, metallurgy, food, chemical industry, electronics.Diatomite because of its porous, and containing clay mineral, has stronger plasticity-, cohesiveness, coking property, has certain intensity and hardness, can improve in brief introduction, improve mechanical property as filler after processing.
Summary of the invention
The object of the invention is to for deficiency of the prior art, a kind of full-bodied tire air-tight layer rubber material composition is provided.
For solving the problems of the technologies described above, the present invention adopts following technical scheme to realize:
A kind of full-bodied tire air-tight layer rubber material composition, is characterized in that: the component of described sizing composition and the parts by weight of content thereof are:
Brominated butyl rubber 75-85
