Description

One-step vulcanization molding solid tire manufacturing process

Technical Field

The invention relates to the technical field of tire manufacturing processes, in particular to a manufacturing process of a solid tire molded by one-time vulcanization.

Background

When current solid tyre preparation, fill in the good expanded polystyrene core of preforming in fashioned tire inside, adorn wheel hub, push into the vulcanizing boiler and vulcanize, the defect that this technology exists lies in: the process has the biggest defect that secondary vulcanization is needed, and various physical indexes such as the wear resistance, the strength and the like of the tire are greatly reduced after the tire is subjected to secondary high-temperature vulcanization, so that the normal service life of the tire is seriously influenced.

Disclosure of Invention

The invention aims to provide a manufacturing process for a solid tire through one-time vulcanization molding, which aims to solve the problem that the service life of the tire is seriously influenced because secondary vulcanization is needed in the existing process for preparing the solid tire in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme:

the one-step vulcanization molding solid tire manufacturing process comprises the following steps:

s1: preparing materials; preparing a wear-resistant layer adhesive layer, a cord fabric framework layer, an air-tight layer adhesive layer and a foaming adhesive layer by adopting the existing preparation process;

s2: forming a tire; firstly, sticking a foaming glue layer on a tire forming machine, then sequentially sticking an airtight layer glue layer, a cord fabric framework layer and a wear layer glue layer, and arranging steel wire rings on two sides to form a green tire;

s3: vulcanizing; the green tire molded in step S2 is loaded on a vulcanizer and subjected to a suitable time and suitable conditions in a mold to be once vulcanized into a finished solid tire.

The secondary vulcanized gasoline cleaning and the mucilage coating are omitted, and the raw materials and the production cost are reduced.

Preferably, the temperature for vulcanization in step S3 is 145-155 ℃.

Preferably, the time for vulcanization in step S3 is 20 to 40 minutes.

The process of the material preparation link adopts the existing tire manufacturing process, and is not described herein again.

Compared with the prior art, the invention has the beneficial effects that: this application is at the inside wall preforming foaming glue layer of cover tire, then through once vulcanize foaming glue layer can directly be full of in the child die cavity of cover tire, combine as an organic whole with the cover tire, the injury that the secondary vulcanization caused the tire is avoided completely to the finished product solid tyre of one shot forming, in the course of the manufacture, owing to reduced process flow, the cost can reduce fifty percent, and need not gasoline, only with vulcanize the steam of cover tire can, practiced thrift gasoline and natural gas energy.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments of the present invention, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a technical scheme that:

the one-step vulcanization molding solid tire manufacturing process comprises the following steps:

s1: preparing materials; preparing a wear-resistant layer adhesive layer, a cord fabric framework layer, an air-tight layer adhesive layer and a foaming adhesive layer by adopting the existing preparation process;

s2: forming a tire; firstly, sticking a foaming glue layer on a tire forming machine, then sequentially sticking an airtight layer glue layer, a cord fabric framework layer and a wear layer glue layer, and arranging steel wire rings on two sides to form a green tire;

s3: vulcanizing; the green tire molded in step S2 is loaded on a vulcanizer and subjected to a suitable time and suitable conditions in a mold to be once vulcanized into a finished solid tire.

The original gasoline cleaning and mucilage coating on the inner wall of the tire after secondary vulcanization are omitted, and the raw materials and production cost are reduced.

The temperature of vulcanization in step S3 was about 155 ℃ and the time of vulcanization in step S3 was about 30 minutes. The vulcanization parameters can be adjusted according to actual conditions;

the process of the material preparation link adopts the existing tire manufacturing process, and is not described herein again;

this application is at the inside wall preforming foaming glue layer of cover tire, then through once vulcanize foaming glue layer can directly be full of in the child die cavity of cover tire, combine as an organic whole with the cover tire, the injury that the secondary vulcanization caused the tire is avoided completely to the finished product solid tyre of one shot forming, in the course of the manufacture, owing to reduced process flow, the cost can reduce fifty percent, and need not gasoline, only with vulcanize the steam of cover tire can, practiced thrift gasoline and natural gas energy.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
