Description
Technical field
The present invention relates to type material, especially a kind of caster oil type polyurethane material and preparation method.
Background technology
China impregnating material system with in the glass steel lining, epoxy steel, fiber glass fiber reinforced plastic, furan south glass reinforced plastic, bad oxygen clay, siliceous clay, polyoxyethylene resin, polyethylene is stuck with paste and pitch prill etc.Mostly be that system is hard, system software is pasted to the position again, or be in harmonious proportion with powder and use that cost an arm and a leg, purposes is single, the constructing operation complexity causes quite difficulty to the user, does not reach protection effect again, only polishing rust cleaning engineering unusual difficulty just just.
Interpenetrating net polymer is called for short IPN and is the novel multiphase polymer material of a class that two or more polymkeric substance IPN is become the interleaving network shape with chemical process.This material is that the seventies begins to develop in the world, and has caused people's attention widely.But, also make production technique too complicated because this material require is at high temperature synthetic and curing, thereby has limited their use range.
The applicant had once proposed the patent of invention that a kind of name is called " interpenetrating polymer networks material of castor oil type polyurethane fat and poly-substituted ethylene and preparation method " on April 20th, 1998 to Patent Office of the People's Republic of China, and application number is: 98113508.0.This patent application also is not very perfect technically.
Summary of the invention
Main purpose of the present invention is to provide a kind of can synthesize the also caster oil type polyurethane material of curing molding at normal temperatures, make it have the good anti-mill performance of dashing, hydrolysis, gasproof erosion, acid-and base-resisting, salt, solvent also possess high strength and snappiness, and technical mature and reliable.
Above-mentioned purpose of the present invention is achieved through the following technical solutions.A kind of caster oil type polyurethane material, its special character are that the composition of raw materials of this material is (is benchmark with the 1000g finished product):
Viscotrol C (dehydration) 320-324g
