Abstract
The present invention belongs to the field of sealing material, which adopts non-asbestos fibers as a basic framework of the sealing material, and mechanical property of the material is enhanced. The present invention comprises inorganic fibers and organic fibers, butyronitrile rubber powder, various fillers, pigments and various accessory ingredients, wherein the butyronitrile rubber powder is from 10 to 20%; the organic fibers comprise 1 to 10% aramid fibera and 1 to 10% cellulose; the inorganic fibers comprise 30 to 60% sepiolite, 0 to 10% aluminum silicate, and 0 to 10% brucite; the accessory ingredients comprise 1 to 5% sulfurized addition agents, 0.1 to 2% lead stearate, and 0.1 to 2% N, N' double (2-benzothiazole di thio) piperazine; the fillers comprise 1 to 10% calcium carbonate, 0 to 10% barium sulfate, and 0 to 10% kaolin; the pigments comprise 0 to 5% carbon black, 0 to 2% chromic oxide and 0 to 2% pigment scarlet. The present invention adopting a powder adhesive production technology has the advantages that compatibility among components is good, the damage to environment and human beings because of volatilization of solvent systems is overcome, and production cost is reduced because solvents are not used; the present invention has the advantages of convenient production, high efficiency, environmental protection and low production cost.
Description
Technical field
The invention belongs to the sealing material field, refer in particular to a kind of secret closure material of solvent-free non-asbestos ring and preparation technology.
Background technology
The sealing material technology that industry is at present produced is: paracril is dissolved as glue with benzene, in mill, mixes banburying with other component process, through each workshop sections such as calendering, sulfidization moldings, produce caulking gum sheet material again.For cooperating this technology, need use a large amount of deleterious solvent benzols and cause that easily the asbestos of cancer are strongthener, this severe contamination environment with endangered workers'health, human body is caused damage, can not satisfy the needs of market and manufacturer.Patent 00111702 " sealing material production method " is exactly the sealing material technology that relatively more typical employing is solvent method production, its system because to adopt toluene or benzene in production process be dissolution with solvents paracril solvation method, human body and environment are produced harm, therefore need the new production technique of invention to solve the problem of environmental pollution that the solvent production method is brought.
Summary of the invention
The objective of the invention is exactly for a kind of method of a kind of solvent-free production sealing material that provides because of solvent production method volatilization objectionable impurities is provided.And on formulating of recipe, taken into full account the harm of asbestos, and adopted the basic framework of non-asbestos fiber material in the present invention as sealing material, reach the purpose of strongthener mechanical property.
The component of the present invention's prescription comprises inorganic fibre and organic fibre, acrylonitrile-butadiene rubber powder, various fillers, pigment, various auxiliary agent.Its particular content is as follows: acrylonitrile-butadiene rubber powder 10-20%, organic fibre: aramid fiber 1-10%, Mierocrystalline cellulose 1-10%; Inorganic fibre: sepiolite 30-60%, pure aluminium silicate 0-10%, brucite 0-10%; Auxiliary agent: vulcanizing ingredient 1-5%, lead stearate 0.1-2%, N, N '-two (2-[4-morpholinodithio dithio) croak piperazine 0.1-2%; Filler: lime carbonate 1-10%, barium sulfate 0-10%, kaolin 0-10%; Pigment: carbon black 0-5%, chromium sesquioxide 0-2%, bright red 0-2%.
Its preparation technology is as follows:
Fiber and filler with → mix banburying → calendering formation → sulfuration → volume duty
And glue mixes
It uses the sealing material manufacture method:
After the pre-mixing of above-mentioned manufacturing sealing material, after mixing and banburying on the feeding machine, feeding is shaped to rolling press, vulcanizes on vulcanizer again, batches packing.
Compared with prior art, advantage of the present invention is under the prerequisite that guarantees environmental protection, adopt the powder adhesives production technology, compatibleness is good between each component, overcome the environmental pollution that brought because of solvent system volatilization and, simultaneously, reduced production cost because of not using solvent to the harm of human body,, have convenient for production, environmental protection, advantage that production cost is low because thereby serialization production improved production efficiency.
