Abstract
The chloroprene rubber adhesive is prepared with chloroprene rubber, cyclopentane-B solvent, methyl ethyl ketone, ethyl acetate, No. 120 solvent gasoline, tert-butyl phenolic resin, magnesium oxide, zinc oxide and benzoic acid-water catalyst. The present invention uses no toxic benzene solvent, and has less environmental pollution and harm to human body, and the product has good brushing performance, high adhesive strength, high lasting property and other advantages.
Description
Technical field
The invention belongs to technical field of adhesive, specifically a kind of neoprene adhesive and preparation method thereof.
Background technology
Neoprene adhesive is a kind of solvent borne tackiness agent, and it has cohesiveness preferably, and the title of " multi-purpose adhesive " is arranged.The preparation method of traditional neoprene adhesive is with the rubber mixing machine roll-in polymkeric substance of plasticating, to cut off molecular chain, destroy the gel in the polymkeric substance, thereby improve the denseness of solution, and in mixing, add partly metal oxide, make it evenly, smoothly, and then mixing film is cut into inch strips and grain, in closed container that has agitator or super mixer, be dissolved in solvent.This method manufacturing cost and facility investment are bigger, and labor strength is big, and the problem of environmental pollution is difficult to solve.
In addition; traditional neoprene adhesive contains more benzene kind solvent; existing national standard " GB18583-2001 " to solvent-borne type rubber based adhesives regulation benzene less than 0.5%, benzene adds dimethylbenzene and toluene less than 20%; benzene kind solvent, these solvents of still allowing below 20% are unfavorable for environment protection, also are unfavorable for constructor's physical and mental health.
Summary of the invention
The objective of the invention is to overcome existing technical disadvantages, a kind of new prescription and preparation method of neoprene adhesive is provided.
The composition of neoprene adhesive of the present invention and to contain weight percentage as follows:
2442 chloroprene rubber 16.5-18.5%, pentamethylene Type B solvent 46～52%, methylethylketone 2～4%, vinyl acetic monomer 16～18%, 120
#Gasoline 3～5%, 2402 tert butyl phenolic resins 7.5～9.5%, magnesium oxide 1.5～5.5%, zinc oxide 0.2～0.5%, phenylformic acid 0.03～0.05%, water 0.01～0.03%.
Above-mentioned industrial chemicals thing is the commercially available prod, and wherein said 2442 chloroprene rubbers are that long-lived chemical plant, Sichuan produces, and described pentamethylene Type B solvent is produced for Wal, Maoming reaches the chemical plant, and described 2402 tert butyl phenolic resins are produced for the chemical plant that draws water.
Neoprene adhesive preparation method of the present invention may further comprise the steps:
With chloroprene rubber, pentamethylene Type B solvent, vinyl acetic monomer, methylethylketone, 120# gasoline oxidation magnesium, zinc oxide, phenylformic acid, 2402 tert butyl phenolic resins and water once drop in the mixing tank of being with the sealing of stirring, rotating speed is 100～200 rev/mins, stir and stopped after (agitator must add the emptying valve) in 6～8 hours stirring, start and agitator banded toothed gear pump, material is extracted out from the bottom of stirring device, after shearing, squeezes into by toothed gear pump the top of agitator again, so circulation is 6～12 hours, till when product viscosity and brushing characteristic are qualified, stirring and starter receiver pump after a few hours, temperature of charge can rise by nature in the agitator, but is advisable to be no more than 50 ℃.The type selecting of described toothed gear pump is selected according to agitator vessel size, generally by per 1 cubic metre choose flow be 20～30 cubic metres/time toothed gear pump.
Advantage of the present invention and effect are as follows:
(1) is dissolved in aromatization according to neoprene adhesive and contains thing, be insoluble to aliphatic hydrocarbon and ester compound, but be dissolved in the characteristics of various ternarys or quaternary mixed solvent, the present invention is according to " similar mixing and the hydrogen bond index of solubility parameter and solvent ", draw through tens of tests, adopt pentamethylene Type B solvent, vinyl acetic monomer, methylethylketone, 120
#Industrial naptha cooperates in certain proportion, can dissolve chloroprene rubber fully, and therefore triphen content of the present invention is lower than 0.5%, has solved existing technology pollution problem.
(2) preparation method of the present invention adopts the toothed gear pump circulation to replace rubber mixing machine to shear the neoprene latex molecular chain, destroy the gel in the neoprene latex, helping moiety looses evenly, facts have proved, the neoprene adhesive that adopts method of the present invention to make, its brushing performance, workability all are better than the neoprene adhesive that rubber mixing machine is produced, and have reduced energy consumption, have alleviated working strength of workers.
(3) the present invention adopts homemade (Sichuan long-lived chemical industry worker produce) 2442 chloroprene rubber import substitution chloroprene rubbers, cohesive strength and import glue are more or less the same, mainly be that gel content is big, adopt rubber mixing technique and general dispersing apparatus to consume energy big, labor strength is big, the brushing poor performance, and adopt the toothed gear pump circulation can reach the brushing performance of import glue fully.
(4) tackiness agent of making according to prescription of the present invention and preparation method, intensity is set up fast, and stability in storage is good, is difficult for layering, bright property is good, has overcome the easy stratified disadvantage of neoprene adhesive, and shock-resistant and vibration, good endurance, oil resistant, water-fast, acid and alkali-resistance, easy to use, price is low.
