Abstract
The invention discloses an open fire-retarding adhesive, which is prepared by using neoprene and resins 210 and 2402 as the raw materials, using chloroethylene and dichloromethane as a solvent and adding a proper amount of magnesium oxide and age resister and performing reaction at normal temperature. The adhesive has a shearing strength of 402N/cm2 and the characteristics of open fire retarding, quick solidification, high adhering strength and the like. The adhesive is widely used for adhering cotton canvas cores, polyvinyl alcohol fibers and nylon conveyer belt connectors as well as rubber, chemical fibers, cotton fabrics, leather, bamboo/wood, decorative materials and part of plastics.
Description
The present invention relates to a kind of open fire-retarding adhesive.
At present, be used for the bonding main two class tackiness agent of conveying band joint and exist a lot of problems: a class is to have the high normal temperature cured type tackiness agent of cohesive strength, but belongs to inflammable articles, is not suitable for emphasis fire prevention units such as colliery, thermal power plant and uses; Another kind of is have that strength of joint is big, heat vulcanization type tackiness agent that life cycle is long, but complex process, need shortcoming high temperature vulcanized, that joint is made and curing time is long also fairly obvious.
Purpose of the present invention is exactly in order to produce the bonding open fire-retarding adhesives of conveying band joint such as a kind of cotton duck core, polyvinyl, nylon, not only cohesive strength is higher for it, and can meet the non-combustible novel refractory adhesive of naked light, be specially adapted to the colliery, emphasis such as firepower electrical plant fire prevention unit.
Realize that technical scheme of the present invention is: by containing (1) neoprene latex 90-125 weight part, (2) 210 type resin 14-30 weight parts (3) 2402 type resin 5-10 weight part (4) trieline 400-750 weight part (5) methylene dichloride 150-250 weight parts, (6) magnesium oxide 0.04-0.1 weight part (7) anti-aging agent 0.5-1.5 weight part is formed.
Production technique of the present invention is simple, and mix glue, 210 resins, trieline, methylene dichloride under the chlorine earlier mutually (1) at normal temperatures.(2) then 2402 resins, magnesium oxide, trieline are mixed mutually.(3) at last twice reactant mixed mutually, and add anti-aging agent.
Embodiment 1
By neoprene latex 92 weight parts, 210 resins, 12 weight parts, 2402 type resins, 5 weight parts.Three thermal source ethene, 405 weight parts, methylene dichloride 153 weight parts, magnesium oxide 0.04 weight part, anti-aging agent 0.5 weight part is formed.
Embodiment 2:
By neoprene latex 105 weight parts, 210 resins, 20 weight parts, 2402 resins, 8 weight parts, trieline 550 weight parts.Methylene dichloride 210 weight parts, magnesium oxide 0.08 weight part.Anti-aging agent 0.6 weight part is formed.
Cohesive strength height of the present invention, shearing resistance can reach every square metre of 210N in 20 minutes, and final shearing resistance is every square metre of 402N, and stripping strength is 252N/25cm.Have especially and meet naked light and do not burn, characteristics such as quick solidifying can be widely used in the cotton duck core, and polyvinyl, nylon conveyer belt joint normal temperature are bonding fast, also are suitable for the bonding of rubber, chemical fibre, cotton fabric, leather, bamboo wood, finishing material and partly plastic.
The present invention is simple for production, low cost, and the advantage of durable is the in the market optimal selection of like product.
