Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, and more specifically, it relates to a vulcanization device for preparing ceramicized silicone rubber. Background Technology

[0002] Ceramicized silicone rubber is a special material that can form a hard ceramic body when exposed to fire. It is widely used in fields such as fireproof layers for wires and cables. Vulcanization is a key process in its preparation. By heating, the rubber molecules cross-link and solidify, giving the material stable physical properties. Traditional vulcanization equipment has many limitations. Early equipment often used ordinary ovens, which resulted in uneven heating, leading to local over- or under-vulcanization of the rubber, affecting product consistency. Some equipment had poor sealing, resulting in serious heat loss, high energy consumption, and low vulcanization efficiency. Others could not accurately control the temperature and time, making it difficult to meet the strict requirements of ceramicized silicone rubber for high temperature and holding time.

[0003] Chinese utility model patent with publication number CN222819371U discloses a high-temperature vulcanization device for silicone rubber. However, this patent lacks a cooling device for the rubber sleeve and only supports the rubber sleeve through an internal expansion clamp, which can easily lead to product deformation and damage. At the same time, the shaft and sleeve are integrated, making it difficult to clean the sleeve and affecting the subsequent production quality.

[0004] In existing technologies, traditional vulcanization devices mostly use static heating, resulting in large differences in heating in different parts of the raw material, leading to inconsistent vulcanization degrees, insufficient or excessive cross-linking in some areas, which affects the fire resistance and mechanical strength of ceramicized silicone rubber.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a vulcanization apparatus for preparing ceramicized silicone rubber, which has the following beneficial effects:

[0018] 1. The rotating motor drives the rotating disk to rotate circumferentially, while the rotating gear meshes with the rotating gear ring to drive the rotating rod to rotate on its own. This causes the raw material on the sleeve rod to both revolve around the center of the machine box and rotate on its own, so that it can fully contact the high-temperature steam sprayed from the steam nozzle, thereby improving the uniformity of vulcanization.

[0019] 2. After vulcanization, cool water is injected into the cavity of the water inlet plate, rotating rod, and sleeve rod through the water inlet pipe. By utilizing the direct heat exchange between the inner wall of the sleeve rod and the rubber, the temperature of the raw material is rapidly reduced. At low temperatures, the hardness of the rubber increases, reducing the product breakage rate and improving the product qualification rate.

[0020] 3. By rotating the movable sleeve, the connecting rod is driven to insert / disengage from the connecting hole along the movable groove. With the connecting block of the connecting plate and the connecting groove in place, the sleeve rod and the rotating rod can be fixed or separated. After the sleeve rod is detached, residual rubber on the surface can be thoroughly cleaned, and sleeve rods of different diameters can be quickly replaced. It is compatible with various specifications of ceramicized silicone rubber products without the need to adjust the main body of the equipment. Attached Figure Description
