Description
Technical field
The present invention relates to rubber product technical field, specially a kind of preparation method of hollow rubber body.
Background technique
Rubber product is many kinds of, but production process is essentially identical.With general solid rubber --- raw rubber is original
The basic craft course of the rubber product of material includes: 6 basic working procedures such as plasticate, be kneaded, rolling, extruding, forming, vulcanizing.It is logical
Often, solid rubber product is molded by mold, is all relatively good processing, but the processing of hollow rubber bodies gets up and is not just
It is easily worked obtained.The common preparation method of hollow rubber body mainly has: the inflatable molding practice, is blown at the liner type molding practice
The glue formula practice, the filling plastic practice.In these methods, but it is most commonly seen with the liner type molding practice.
The conventional liner type molding practice generally includes following steps: rubber compounding ingredient；Rubber compounding is passed through into mixing；
Mill, preforming rubber block；Design sulfurizing mould；Two halves rubber bodies are pressed and molded by mold, go extra leftover pieces, hollow rubber
Colloid edging；Glue on rubber bodies edge；Two semi-closed of rubber bodies；Sulfidization molding takes out finished product hollow rubber body.Above-mentioned technique
It needs two halfbody docking applying gluing knot, technique is cumbersome, and the product mechanical property prepared is affected by adhesive, by force
Degree and performance are still to be improved.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of preparation method of hollow rubber body, this method rubber pattern
Pressure vulcanization is integrally formed, and processing step is simple, and greatly improves the intensity of rubber bodies.
The technical solution of the application are as follows: a kind of preparation method of hollow rubber body, including following preparation step: (1) basis
Rubber compounding carries out ingredient；(2) rubber raw materials are subjected to mixing, mill, pre-formed sheet material；(3) prepare sulfurizing mould；(4) lead to
Cross upper and lower hollow mould charging aperture be added rubber mass, in 150-160 DEG C be molded 2 seconds it is preforming, be then opened, take out it is hollow
Plate in body forms the rubber bodies up and down of unvulcanized maturation；(5) it molds again, rubber bodies collide form pressure up and down, in Xiang Tongwen
It is heated 20 seconds under the conditions of degree；(6) sulfidization molding；(7) rubber rim charge is removed, it is body formed to obtain hollow rubber.
Preferably, sulfurizing mould includes plate in upper and lower hollow mould and hollow body.
Preferably, it is 140-160 DEG C that the process conditions of sulfidization molding, which are the temperature of vulcanization, in step (6), the pressure of vulcanization
For 2.5-6MPa, the time of vulcanization is 0.5-3.5 hours.
The invention also discloses the hollow rubber body being prepared using the above method, which does not use additional glue
Knot agent is bonded.
A kind of preparation method of hollow rubber body provided by the present application is molded vulcanization using rubber and is integrally formed, and reduces empty
The processing step that heart body is formed increases the adhesive strength of two halves rubber bodies, greatly without using adhesive in product preparation engineering
Production cost and production cycle are reduced greatly.After tested, tensile strength 15MPa is realized using the hollow rubber body of this method preparation
Above, elongation rate of tensile failure (EB) 750% or more, shore hardness (HS) 50 ± 3A.
Detailed description of the invention
Fig. 1 is the mold structure diagram that the present invention uses；
