Abstract
The present invention discloses a rubber plate of vermiculite and a preparation method thereof. The properties of light bulk weight, corrosion resistance, no poison, good pressure-resistant performance and heat-insulation performance, etc. of the vermiculite are utilized, rubber, an accelerating agent, an auxiliary accelerating agent and an anti-aging agent are matched, and a sealing material which has the heat-resistant performance and abrasive resistance can be manufactured through glue refinement, mixed refinement, sheet forming and sulfidation. The present invention can be completely used for replacing an asbestos rubber plate. The present invention has the advantages of simple preparation method, no environment pollution, low product cost and easy machining, and has strong competitive power and a wide market perspective.
Description
Technical field
The present invention relates to a kind of vermiculite rebber plate, is the substitute products of sealing materials such as asbestos rubber, belongs to rubber combined sheet material and preparing technical field thereof.
Background technology
Asbestos, rubber plate are use always heat-resisting, oil resistant, acidproof and electrically insulating material, have physical strength and elasticity preferably, as sealing material, use till today, but its processing process have pollution to environment always, and labor condition is abominable, and the people is caused a disease.Therefore, along with society and expanding economy, particularly human reinforcement to environmental protection understanding, the application of above-mentioned sealing material is restricted.China is expected to progressively forbid later on producing and use asbestos rubber goods in 2003.So, seek a kind of substitute products of asbestos rubber material, become industry question of common concern.
Summary of the invention
The object of the present invention is to provide a kind of vermiculite rebber plate, it has quite high physical strength and certain elasticity, can make various rubber plates according to service requirements, is used for polytype sealing occasion.
The present invention also aims to provide a kind of preparation method of vermiculite rebber plate.
Design of the present invention is such.Vermiculite is extensively to be present in nature in vermiculite concentrate mode, vermiculite and asbestos characteristic are relatively, its intensity, thermotolerance, wear resistance all are better than the latter, characteristic such as particularly vermiculite has that unit weight is light, corrosion-resistant, nontoxic, resistance to compression and thermal insulation are good, therefore can be used for manufacturing sealing material, with itself and rubber mix, add some subsidiary material again, as promotor and anti-aging agent, add some weighting agents again, and as other paronite again through sulfidizing, the just vermiculite rebber plate that available can be good.Consisting of of concrete vermiculite rebber plate of the present invention: rubber, vermiculite, vulcanizing agent, promotor, anti-aging agent and weighting agent, composition is expressed as by weight: rubber: vermiculite: vulcanizing agent: promotor: anti-aging agent: weighting agent=20-30: 50-80: 2-3: 0.2-1: 0.1-1: 3-30.Used vulcanizing agent is a sulphur in the prescription, promotor is commonly used is a kind of among captax (α-benzothiazolyl mercaptan), altax (dibenzothiazyl disulfide), vulkacit D (vulkacit D) and the TM monex TD (tetramethyl-thiuram disulfide) or their any mixture, anti-aging agent is antioxidant d (a N-phenyl-2-naphthylamines), and weighting agent is used a kind of in mica, resin, zinc oxide, iron oxide red, the carbon black or their mixture always.Used promotor, anti-aging agent and weighting agent market are on sale, buy easily.
In the present invention, according to different requirements, the rubber of selecting for use can be: a kind of or its composition in natural gum, butadiene-styrene rubber, butadiene-acrylonitrile rubber, neoprene latex, fluorine glue, the silica gel.
Used vermiculite is all expansion acquisitions about 1000 ℃ of vermiculite concentrate.Its Chemical Composition contains: SiO
2, MgO, Al
2O
3, CaO, Fe
2O
3And other composition.
Its molecular formula is as follows: (MgFe
2)
3[(SiAl)
4O

The preparation method of vermiculite rebber plate of the present invention comprises the steps:
(1) refining glue
Treated rubber is plasticated in opening rubber mixing machine evenly;
(2) mixing
With various additives progressively join in the even glue of refining mixing evenly, temperature control 30-60 ℃, time 20-50 minute;
(3) become to open
The repressed sheet material of doing all size, shape.
(4) sulfuration
Cure conditions is controlled at: temperature 150-180 ℃, and pressure 8-10Mpa, time 20-40 minute.
(5) finished product packing
In aforesaid method, mixing process will be complied with different rubber raw materials, and control rubber roll temperature, principle are refining to be opened in the glue refining spare.Become to open and sulfuration process and paronite roughly the same.
The obtained technique effect of the present invention is:
The vermiculite rebber plate performance is better than paronite, is the alternative environmentfriendly products of paronite, meets national industrial policies, has the stronger market competitiveness, has a extensive future, and its production process is pollution-free, and production method is simple, has reduced production cost.
