Embodiment 1

[0045] 1) Build an aerosol-type rubber conveyor belt release agent spraying device

[0046] see figure 1 and figure 2 , as a specific embodiment, the aerosol-type rubber conveyor belt release agent spraying device of the present invention includes an aerosol pipeline 3 arranged on the side of the vulcanizer along the length direction of the vulcanizer, and the aerosol pipeline 3 is in the height direction of the vulcanizer Located in the middle of the upper vulcanization plate 1 and the lower vulcanization plate 2 when it is in an open state; one end of the aerosol pipeline 3 is sealed, and the other end communicates with the aerosol tank 4 through a connecting pipe 7; , on the side facing the vulcanizing machine, a set of spray hole groups is arranged every 300mm along the length direction, and the spray hole groups include upper, middle and lower distribution of upper spray holes 31 and middle spray holes arranged radially toward the gas mist pipeline 3 32 and the lower s...

Embodiment 2

[0053] The difference from Example 1 is that in this example, the amount of each raw material component of the release agent is: 23 parts of high-viscosity polyether silicone oil, 2.4 parts of fluorosurfactant, 2.3 parts of glycerin, 7.5 parts of low-viscosity silicone oil, 36 parts of ethanol, 1.5 parts of Span 80, 25 parts of HFO-1234ze, 55 parts of hydrofluoroalkane 134a. In the spraying system: the length of the aerosol pipeline 3 is 3.2m, the middle spray hole 32 is located in the middle of the aerosol pipeline, the circumferential interval angle between the lower spray hole 33 and the middle spray hole 32 is 25 degrees, and the upper spray hole 31 and the middle spray hole The circumferential interval angle of the holes 32 is 40 degrees, the aperture of the upper spray hole 31 is 0.9mm, the aperture of the middle spray hole 32 is 0.7mm, the aperture of the lower spray hole 33 is 0.58mm, and the spray hole group interval is 310mm .

Embodiment 3

[0055] The difference from Example 1 is that in this example, the amount of each raw material component of the release agent is: 28 parts of high-viscosity polyether silicone oil, 2 parts of fluorosurfactant, 2.7 parts of glycerin, 6 parts of low-viscosity silicone oil, 30 parts of ethanol, 1 part of Span 80, 20 parts of HFO-1234ze, 53 parts of hydrofluoroalkane 134a. In the spraying system: the length of the aerosol pipeline 3 is 3.5m, the middle spray hole 32 is located in the middle of the aerosol pipeline, the circumferential interval angle between the lower spray hole 3 and the middle spray hole 2 is 20 degrees, and the upper spray hole 31 and the middle spray hole The circumferential interval angle of the holes 32 is 35 degrees, the hole of the upper spray hole 31 is 0.8mm, the aperture of the middle spray hole 32 is 0.6mm, the aperture of the lower spray hole 3 is 0.5mm, and the spray hole group interval is 350mm .

Abstract

The invention relates to an aerosol type rubber conveyer belt releasing agent, a preparation method thereof and a spraying system thereof. The aerosol type rubber conveyer belt releasing agent is prepared from the raw materials including, by weight part, 20-30 parts of high-viscosity silicone oil, 2-3 parts of fluorinated surfactant, 2-3 parts of glycerin, 6-8 parts of low-viscosity silicone oil,20-40 parts of ethyl alcohol, 1-2 parts of Span-80, 20-30 parts of HFO-1234ze and 50-60 parts of hydrofluoroalkane 134a. The aerosol type rubber conveyer belt releasing agent has the advantages of being low in consumption, good in chemical stability, high in lubricating property and the like, thereby being applicable to rubber conveyer belt production. Correspondingly the invention also provides the preparation method of the aerosol type rubber conveyer belt releasing agent. Besides, the invention also provides the aerosol type rubber conveyer belt releasing agent spraying system for sprayingthe aerosol type rubber conveyer belt releasing agent onto the upper and lower curing plates on a curing press.

Description

technical field [0001] The invention relates to the production technology of rubber conveyor belts, in particular to an aerosol-type release agent for rubber conveyor belts, a preparation method and a spraying system thereof. Background technique [0002] Rubber conveyor belts are resistant to tropical belts, wear-resistant belts, burning-resistant belts, oil-resistant belts, alkali-resistant belts, cold-resistant belts, etc., and are widely used in various mining, metallurgy, steel, coal, hydropower, building materials, chemical, food and other enterprises. Solid material conveying. [0003] Vulcanization (also known as crosslinking and curing) is an important link in the production process of rubber conveyor belts. In order to make the finished product can be successfully peeled off from the mold (vulcanized plate) on the vulcanizer after the vulcanization is completed, it is necessary to apply a release agent on the surface of the rubber or the mold before the vulcanizat...
