Polyurethane of mellow dissolve sex (the adhesive that APU) adhesive is a kind of new-style, environmental protection, it overcame solvent polyurethane already (the drawback with PU) adhesive big noxiousness, overcame water of PU of ability in swimming to volatilize again the drawback with efficiency of production of slow, influence and big specific power consumption, it is the new breed adhesive with at present good integral performance. Use get together ether 2 alcohol, toluene methylic third acid mixes ester of 2 different cyanic acid, 2 hydroxide methylic propane is 3 hydroxide basic raw material, synthesized for solvent with acetone get together adhesive of ether anion APU. Discussed to get together beforehand reaction - of NCO/-OH deserve to compare, the element such as the means of feed in raw material of KH-550 of coupling agent of alkyl of cross-linking system, silicon and temperature of enlarge chain reaction is right the influence of APU adhesive function. Get together at the outset N(-NCO)/n(-OH) ratio is 6, control of temperature of reaction of enlarge catenary agent is in (when ℃ of 60 ± 2) , complex gets together ether anion APU is had better mechanical performance and be able to bear or endure ability in swimming, and stability of keep in storage is better.
