Description
Technical field
The present invention relates to a kind of silicane-modified polyurethane resin, and in particular to one kind contains poly- (methyl) acrylate structural
Silicane-modified polyurethane resin.
Background technology
The characteristics of polyurethane has big, wear-resisting adhesive strength, big mechanical strength and good vibration absorption, gluing
Agent, fluid sealant, elastomer field are all widely used.But due to there is free isocyanate, and heat-resisting, water resistance compared with
Weak the features such as, limit polyurethane body and tie up to and apply in more fields.Silicane-modified polyurethane is developed based on problem above
System.
Silicane-modified polyurethane (SPUR) is that the terminal isocyanate group of polyurethane prepolymer is become silane oxygen by reaction
Base, main chain is polyurethanes segment.The silicone segments for introducing low pole and high bond energy cause silane end capped polyurethane
Resistance to water, heat resistance all make moderate progress.Silane end capped polyurethane can be used as one-component silane end capped polyurethane fluid sealant, viscous
Knot agent.
CN103910847A discloses a kind of preparation method of silicane-modified polyurethane oligomer, and the polyurethane for thus preparing is close
Sealing is limited by technique, have selected the polyethers or polyester of relatively low degree of functionality as raw material.This can substantially sacrifice the machinery of polyurethane
Intensity, and the introducing of silicone segments can not still be effectively improved destruction of the resistance to hydrocarbon medium of polyurethane to material.
CN1865313A is provided a kind of hydroxy acrylate and is present on a small quantity in silicane-modified polyurethane with block form
Process for preparing resins, its silane coupler is dihydroxylic alcohols, is present in resinous polymer as chain extender, is solved to a certain extent
The problem of polyurethane acrylate resin heat resistance and the resistance to water of having determined, but operating procedure is complex, and raw material is limited relatively tighter
Weight, increased the difficulty for using.System still be NCO group terminated polymer, increased resin preservation difficulty, and due to
The presence of free isocyanate cannot be avoided, and limit its application in low bio-toxicity field.
It is aqueous poly- to improve with polyacrylate blending that CN101429407A provides a kind of organic silicon modified aqueous polyurethane
The method that urethane resistance to water and weatherability are not enough.The performance deficiency of aqueous polyurethane, the party are solved by the mode of physical entanglement
Method is easy to use, but improvement is general, and the process being blended needs the presence of solvent, this feature of environmental protection with aqueous polyurethane
Can conflict.
The technical scheme of above-mentioned patent mainly includes two ways：A small amount of altered contents are introduced in agent structure, or
Material hybridization is carried out using the mode of physical blending.Both modes all can not inherently improve the resistance to hydrocarbon medium of material
Performance.
