Abstract
A product produced by the method of producing the organic silicone rubber adhesive is a sealing adhesive which possesses performances of insulation, waterproofness, moisture-proof, seal and the like. The sealing adhesive is mainly used for glue jointing electronic components, metals and heatproof non-metallic materials.Glue jointing can be used at a temperature of from minus 60 DEG C to 260 DEG C. The sealing adhesive has good machinability, good physical and mechanical properties, low compression set, good dilatancy for resisting solvents, stability for resisting high pressure steam, excellent cold resistance and insulativity and the like. Raw materials are: methyl vinyl silicone rubber powders, styrene, muscovite powders, asbestos, ethyl orthosilicate, potassium acetate, acrylic acid and silicone resin.
Description
Affiliated technical field:
Product of the present invention belongs to chemical field
Background technology:
The organo-silicone rubber tackiness agent is a kind of sealant.Because silicon rubber has very high resistivity, and its resistance keeps stable in very wide temperature and range of frequency, and silicon rubber has good resistivity to high-voltage corona discharge and arc-over: thereby can be used for positions such as high-tension insulator, TV set high-voltage cap, electrical component; When adding conductive filler material, silicon rubber just has electroconductibility: can be used for positions such as keyboard, conduction point of contact, electrical heating element parts, antistatic component, high-tension cable, medical physiotherapeutic, conductive glue slice; When adding some heat conductive filler, just has thermal conductivity; When adding a small amount of anti-flame agent, it just has flame retardant resistance and self-extinguishing.Tackiness agent with organo-silicone rubber production has purposes widely, and materials such as multiple metal (copper, iron, ferrite, stainless steel, aluminium, alloy etc.), nonmetal (glass, pottery, cement, synthetic glass etc.), plastics, rubber, nylon, textiles, Resins, epoxy, polyacrylate(s), bamboo and wood, cloth, paper are had good tack and bonding force.Because tackiness agent has performances such as insulation, waterproof, protection against the tide and sealing, can be used as coating, the perfusion of appliance electronic component; In building industry, can be used for glueing joint the porcelain subsides stone of sealed doors and windows glass, tunnel, subway, hypogee, also can be used for the gluing of metal frame etc.Product of the present invention is to be the tackiness agent of base-material with the methyl vinyl silicone rubber, and the gained bonded part can use in-60 ℃～260 ℃ temperature ranges.Methyl vinyl silicone rubber is the most general a kind of silicon rubber, at home and abroad occupies an leading position in the production of silicon rubber at present.Because it introduces partly undersaturated vinyl on side chain, make its processing characteristics and physical and mechanical properties better, has less compression set, the stability of solvent-proof preferably swelling property and high pressure resistant steam, good winter hardiness and insulativity etc.
Summary of the invention:
Produce the organo-silicone rubber tackiness agent of different purposes, use different prescriptions and crosslinking curing mode, the invention provides a kind of is the method that base-material is produced the organo-silicone rubber tackiness agent with methyl vinyl silicone rubber, its product is mainly used in and glueds joint electronic devices and components, metal and heat-stable non-metallic material, and the gained bonded part can use in-60 ℃～260 ℃ temperature ranges.Producing the raw material that this tackiness agent uses has: 1. 40 parts in methyl vinyl silicone rubber powder (major ingredient); 2. 30 parts of vinylbenzene (organic solvent, its effect is that methyl vinyl silicone rubber is dissolved as liquid state, does not change the chemical property of methyl vinyl silicone rubber); 3. 10 parts of white mica powders (filler, its effect is: increase the wettability of glue-line to adherend, gain in strength and improve oxidation-resistance, and the acid of the trace that can neutralize); 4. 10 parts in asbestos (filler, its effect is: improve tackiness agent intensity at high temperature, asbestos can prevent the be full of cracks that glue-line produces because of contraction); 5. 2 parts of 2 parts of ethyl orthosilicates, potassium acetate (effect of above two kinds of raw materials is the solidification values that reduce organic silicon adhesive); 6. 3 parts in vinylformic acid (properties-correcting agent can obtain resistance to elevated temperatures and good mechanical property after the modification); 7. 3 parts of silicone resin (tackifier).
The beneficial effect of product of the present invention is: can produce a kind of processing characteristics and physical and mechanical properties better, has less compression set, the tackiness agent of the stability of solvent-proof preferably swelling property and high pressure resistant steam, good winter hardiness and insulativity, this agent can be used for glueing joint electronic devices and components, metal and heat-stable non-metallic material.
