Abstract
The present invention discloses a kind of special defoamer of rubber, by weight percentage, including：Alkymer 30 50%；Hydramine 4 30%；Aliphatic acid 3 25%；Aliphatic acid alkanolamine ester 4 20%；Dispersant 4 10%；Help defoamer 8 18%.50 70 minutes prepared special defoamers of rubber are stirred after above-mentioned substance is added.Wherein hydramine molecular weight is 100 200, and fatty acid molecule amount is 500 800, and aliphatic acid hydramine ester molecule amount is 1,000 1500；It is one or more in lower alcohol, carboxylic acid vinegar, water-insoluble soap to help defoamer, and dispersant is nonionic surface active agent.Defoamer of the invention has antifoaming speed fast, and suds ability is strong, particularly to having good foam-inhibiting effect for the conventional various anion of rubber, plastics-production system, nonionic foaming agent.In the water-based system easily dispersion, self-emulsifying is strong, froth breaking is good, suds are lasting, especially to water soluble polymer and in, low high viscosity systems have special result.Flake point and pinprick phenomenon will not be produced.
Description
Technical field
The present invention relates to defoamer field, more particularly to a kind of special defoamer of rubber production.
Background technology
In rubber industry, be related to rubber cement stir, topple over, flow, filter, deaerate the problems such as when because in system
Kinds of surface activating agent is there is, substantial amounts of foam can be produced, because its composition is complex, one is all brought to froth breaking and suds
Fixed difficulty.
Therefore, prior art has yet to be improved and developed.
The content of the invention
In view of above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of special defoamer of rubber, it is intended to solve
The problem of a large amount of foams is certainly produced in rubber industry.
