Abstract
The invention belongs to the technical field of tread rubber production, and specifically relates to a cut resistant tread rubber for car semi-steel radial tires. The cut resistant tread rubber for car semi-steel radial tires is composed of the following raw materials: polyisoprene rubber, butadiene styrene rubber, sulfur, a promoter CZ, white carbon black, porcellanite, and B type microcrystalline wax. The tread rubber is cut resistant, can effectively prevent the tires from generating shedding layers and cracks in tire groove bottoms, and largely prolongs the service life of car semi-steel radial tires.
Description
Technical field
The invention belongs to the technical field that tread rubber is produced, be specifically related to a kind of tread rubber of resistance to scarfing for car semi-steel radial tire.
Background technology
Tire is to be assemblied on wheel rim or wheel shaft, is the linker between vehicle and road, for the circular ring type elastomerics of vehicle or aircraft operation and landing.A set of tire by the inner tube of a tyre forms by 3 conventionally: cover tire, the inner tube of a tyre, rim strip.Wherein cover tire is for bearing the type shells body of motive power; The inner tube of a tyre is for keeping the interior pressure of tire, with the annular elastomerics of tyre valve; Rim strip for the protection of the inner tube of a tyre endless belt that the face of closing is not subject to wheel rim wearing and tearing.And tyre surface is tread, be tyre protector position, the cover tire glue-line on belt or buffer layer, has certain section form, has decorative pattern.Not only can protect casingply, the buffer layer of wheel crown part to avoid damage; Simultaneously can make there is good gripping power between tire and ground, avoid the longitudinal and lateral movement of tire to affect the rideability of automobile.
Tire is one of major parts of automobile, and for automobile, caing be compared to is people's both feet, is the travel mechanism of automobile.Tire is arranged on the effect of automobile: 1, bear automobile and its institute's weight-carrying capacity, this is called supporting capacity; 2, transmit earthward the reactive force that automobile is sailed, draws, accelerates, turned to and brakes, as functions such as motivating force, tractive force, damping force and steering forces, this is called and adapts to automobile dynamic quality requirement, makes the ability of automobilism; 3, can make that automobile is driven freely under various weathers, road surface and velocity conditions, the function of operation stabilization and high-speed secure, this is called security; 4, damping vibration, reduces noise, takes advantage of the function that seat is comfortable, and this is called comfortableness.
Wherein the body cord orientation of radial is as the terrestrial meridian, centered by wheel shaft, from a tyre bead to another tyre bead, radial array.Although belt cord is diagonal cross, arrange, be very little angle with crown medullary ray.Body cord is arranged interior crown medullary ray by meridian direction and is 90 °; And there is cord to arrange the belt bundle banding carcass that almost approaches circumferential direction.
Along with the development of the raising of automobile driving speed and the improvement of highway pavement, especially motorway, tire quality performance is had higher requirement, mainly contain following basic demand: 1. higher portative power and good shock-absorbing capacity; 2. stronger tractive force and well brake ability; 3. good cornering ability and directional stability ability; 4. good abrasion resistance and endurance quality; 5. high security and low-rolling-resistance.
Car is very different due to road conditions in the process of moving, makes tire very easily produce scarfing and stratum disjunction, on tire, easily at the bottom of generation groove, chaps, and these all will shorten the work-ing life of tyres for passenger cars greatly, have reduced car safe reliability under steam.
Summary of the invention
