Abstract
The invention discloses an adhesive resin with high temperature resistance and high adhesive strength. The adhesive resin comprises the following components in parts by weight: 100 parts of phytic acid modified polyvinyl alcohol resin, 10-40 parts of epoxy resin, 1-5 parts of coupling agent, 20-75 parts of filler and 10-100 parts of solvent. A preparation method of the adhesive resin with high temperature resistance and high adhesive strength comprises the steps: sequentially adding the phytic acid modified polyvinyl alcohol resin and the epoxy resin into a solvent solution, and dispersing in a high-speed dispersing machine until all the resin is completely dissolved to obtain a base material; and mixing the base material, the filler and the coupling agent, grinding and dispersing on a three-roller machine to obtain the adhesive resin with high temperature resistance and high adhesive strength.
Description
Technical field
The present invention relates to a kind of high temperature resistant high bonding force adhering resin.
Background technology
Along with the fast development of China's economy and improving constantly of people's living standard, people are more and more higher to the requirement of the aspects such as safe and reliable, the economic health of water feeding system.In feedwater field, galvanized pipe, cast iron pipe be because water delivery quality is not ideal, and used by some city limits, and single plastics tubing is because its intensity is low, fire-proof shock-proof poor performance, and the easy shortcoming such as aging, use range is also restricted.
Steel-plastics composite pipe is called for short steel and moulds pipe, take steel pipe as base material, not only has intensity and the toughness of steel pipe, and has the advantages such as the environmentally-friendly sanitary of plastic pipe, incrustation, water resistance is not little.Steel-plastics composite pipe is a kind of high-quality, efficient, high strength, environmental protection, moderate Novel composite pipe.This is admitted by national industrial policies support and users several years, and rapidly, market potential is huge in development.Steel-plastics composite pipe divides hot water pipe, but easily come unstuck in the application of the hot-water line of most of steel-plastics composite pipe, cause and leak and then produce potential safety hazard, its major cause is exactly that the hot melt adhesive product performance of bonding steel and plastics are undesirable, cold-resistant right performance is bad, after temperature variation, easily produce offset phenomena.
Meanwhile, on the surface with the bonded metal of comparatively high temps, the quick volatilization of solvent makes to bring larger difficulty in metallic surface bonding.
A kind of high temperature resistant, simultaneously to have fabulous bonding force adhering resin that has is badly in need of in this area.
Summary of the invention
The object of this invention is to provide a kind of high temperature resistant high bonding force adhering resin.
For achieving the above object, a kind of high temperature resistant high bonding force adhering resin, the component that comprises following weight part:
Phytic acid modified polyvinylalcohol resin 100
Epoxy resin 10-40
Coupling agent 1-5
Filler 20-75
Solvent 10-100
The preparation method of phytic acid modified polyvinylalcohol resin is: polyvinyl alcohol is soluble in water, under agitation add phytic acid and catalyst sulfuric acid, at the temperature of 35～50 ℃, carry out esterification, the product of generation obtains phytic acid modified polyvinylalcohol resin through washing, centrifugal drying.
Phytic acid, has another name called phytinic acid or nucite phosphoric acid ester, owing to containing more phosphate group, can be used in modified polyvinyl alcohol, and phytic acid and metal have fabulous cementability simultaneously, can be for bonded metal.Its structural formula is as follows:
In mass parts, the 0.1%-5% that the usage quantity of phytic acid is polyvinyl alcohol.
Described filler is selected from calcium carbonate, silicon-dioxide, titanium dioxide, SILICA FUME.Described filler is preferably nano-sized filler.
Described solvent is selected from one or more in acetone, methyl alcohol, ethanol, butanone.
Described coupling agent is selected from silane coupling agent.
A kind of high temperature resistant high bonding force adhering resin:
In solvent solution, add successively phytic acid modified polyvinylalcohol resin, epoxy resin, in high speed dispersor, be dispersed to all resins and dissolve completely, obtain base-material.Base-material is mixed with filler, coupling agent, and grinding distribution on three-roller, obtains high temperature resistant high bonding force adhering resin.
Beneficial effect of the present invention:
The present invention is by the modification to polyvinyl alcohol, strengthened the consistency of its and other resin, because of phosphate group, strengthened the cohesive strength with metal simultaneously.
By adding SILICA FUME, reduced the cost of binding resin, can improve the tensile strength of binding resin simultaneously, there is good stopping property simultaneously.
