Embodiment Construction

[0009] 1. The components of this formula will be proportioned in different parts by mass, as shown in the following table.

[0010]

[0011] Table 1

[0012]

[0013] Table 2

[0014] Two, the preparation method of above-mentioned each embodiment is all the same, and concrete steps are as follows:

[0015] Step 1: put alicyclic epoxy resin, EPDM rubber, trans-1,4-polyisoprene, nucleating agent, and white carbon black into an internal mixer for mastication, wherein, the dense The rotation speed of the mill is 60r / min-70r / min, the internal pressure is 4Mp-5Mp, the heating temperature is 160°C-165°C, after plasticizing for 2-3min, discharge and stand for 5-7 hours to obtain glue A.

[0016] Step 2: Stir 6 parts of iodonitro blue tetrazolium chloride and 18 parts of ethylene glycol solution evenly to prepare an accelerator for future use.

[0017] Step 3: Put the glue A, vinyl acetate, softener and antioxidant obtained in step 1 into the internal mixer for mixing, and slo...

Abstract

The invention discloses a mucilage glue sheet for tire bonding. The mucilage glue sheet comprises cycloaliphatic epoxide resin, ethylene propylene diene monomer, trans-1,4-polyisoprene, a nucleating agent, white carbon black, vinyl acetate, accelerant, a softener and antioxygen. As an epoxy group of the cycloaliphatic epoxide resin is directly connected onto an alicyclic ring, a compact rigid molecular structure can be formed, and the crosslinking density is increased after the cycloaliphatic epoxide resin is solidified; therefore the heat stability of glue can be enhanced by adding the cycloaliphatic epoxide resin to the formula of the mucilage glue sheet; by adding the nucleating agent to the formula, the crystallization rate of the ethylene propylene diene monomer can be quickened, the crystal density of the ethylene propylene diene monomer can be increased and grain size micronization is promoted, and with the addition of the nucleating agent, the yield strength and the tensile strength of the trans-1,4-polyisoprene are increased, so by refining the modified ethylene propylene diene monomer and the trans-1,4-polyisoprene with other components, the tensile strength, the stress at definite elongation and the elongation at break of the mucilage glue sheet are increased.

Description

technical field [0001] The invention relates to the field of automobile production, in particular to an adhesive sheet used for bonding tires. Background technique [0002] Pneumatic rubber tires are typically manufactured using film-coated steel wire beads with a fiber ply cover. Such structures are well known in the tire industry. This article will refer to such structures as composite structures of the above two parts. [0003] Generally speaking, the steel ring composite structure consists of winding a rubber-coated steel wire into a circular shape (hexagonal in cross-section) and a film covering the steel ring in a certain arrangement. The steel ring and rubber form an integral structure after vulcanization, so that Improve the rigidity of the steel ring, reduce the deformation of the steel ring and prevent the direct contact between the steel ring and the skeleton material in the carcass. [0004] At present, the rim viscose sheet of the all-steel radial tire is mad...
