Description
Technical field
The present invention relates to rubber and plastic field, be specifically related to a kind of high-performance modified polyurethane rubber.
Background technology
Polyurethane rubber is the series of elastic body material on main polymer chain containing more carbamate groups, actually
Polyurethane rubber, referred to as polyurethane rubber or urethane rubber or polyurethane elastomer.Polymer chain is except containing amino
Outside carbamate group, possibly together with ester group, ether, urea groups, aryl and aliphatic chain etc..It is typically by oligomer polyol, many isocyanides
Acid esters and chain extender reaction form.Polyurethane rubber, with the difference of use raw material and proportioning, reactive mode and condition etc., is formed not
Same structure and variety type.But there is also a lot of deficiency in prior art, such as poor water resistance, acid and alkali resistance is poor, high temperature resistant
Property is poor, and using effect is not good enough.
Summary of the invention
It is an object of the invention to provide that one has water-tolerant, chemical proofing is good, heat-resisting quantity is good, intensity
The high-performance modified polyurethane rubber of the feature of high, low cost.
The technical scheme is that, a kind of high-performance modified polyurethane rubber, by polyurethane rubber, filler, resistance toization
Learning medicine agent, high temperature resistant dose, dispersant and heat stabilizer composition, described filler is wollastonite powder, described chemically-resistant medicine
Product agent is EP rubbers, and described high temperature resistant dose is politef, and described dispersant is hydroxyethyl cellulose, described heat stabilizer
For dibasic lead stearate, parts by weight shared by the described each composition of high-performance modified polyurethane rubber are respectively as follows: described polyurethane
Rubber accounts for 76-81 part, and described wollastonite powder accounts for 21-25 part, and described EP rubbers accounts for 13-17 part, and described politef accounts for
10-14 part, described hydroxyethyl cellulose accounts for 7-11 part, and described dibasic lead stearate accounts for 5-9 part.
In a preferred embodiment of the present invention, parts by weight tool shared by the described each composition of high-performance modified polyurethane rubber
Body is: described polyurethane rubber accounts for 77 parts, and described wollastonite powder accounts for 22 parts, and described EP rubbers accounts for 14 parts, described polytetrafluoro
Ethylene accounts for 11 parts, and described hydroxyethyl cellulose accounts for 8 parts, and described dibasic lead stearate accounts for 6 parts.
In a preferred embodiment of the present invention, parts by weight tool shared by the described each composition of high-performance modified polyurethane rubber
Body is: described polyurethane rubber accounts for 80 parts, and described wollastonite powder accounts for 24 parts, and described EP rubbers accounts for 16 parts, described polytetrafluoro
Ethylene accounts for 13 parts, and described hydroxyethyl cellulose accounts for 10 parts, and described dibasic lead stearate accounts for 8 parts.
Of the present invention for a kind of high-performance modified polyurethane rubber, this product has water-tolerant, chemical proofing
Well, heat-resisting quantity is good, intensity is high, the feature of low cost.
