Description
Technical field
The present invention relates to fiberglass viscose glue technical field, more particularly to a kind of GRP pipe adhesive.
Background technology
Some defects are frequently present of currently for GRP pipe adhesive, such as bonding strength with fiberglass is relatively low,
Easily ftractureed in prolonged sewage immersion process（Particularly it is used for the glass fiber reinforced plastics product of conduit pipeline）.Additionally, due to glass
The rigidity of steel is larger, when colliding, the existing easy degumming of adhesive.
The content of the invention
The invention aims to solve the above problems, there is provided a kind of GRP pipe adhesive.This adhesive pin
To fitting for Plastic internal decorative layer and fiberglass, laminating intensity is not only increased, service life is also improved.
In order to reach foregoing invention purpose, the present invention uses following technical scheme：
A kind of GRP pipe adhesive, the adhesive is counted including following each component by weight：Novolac epoxy resin 20-
25 parts, 10-13 parts of polyisoprene rubber, 2-3 parts of triisopropanolamine, 1.3-2.2 parts of 6-caprolactone, hydroxy-ethyl acrylate 1-2
Part, 4-4.5 parts of adipic anhydride, 3-7 parts of diisocyanate, 0.3-0.5 parts of polytetrafluoroethylene (PTFE), trimethylolpropane trimethacrylate
4-7 parts, 12-16 parts of butyl acetate.
Novolac epoxy resin and polyisoprene rubber are combined, as the stock of adhesive, with preferably certainly
Body stability, the layer that adhesive formation can be made thicker, so as to adapt to the gluing operations in different gaps.
Triisopropanolamine not only improves overall intensity, can also improve the dispersive property of system, while triisopropanolamine
Can be with,
Diisocyanate can improve intensity and caking property of the adhesive in big thickness during the use of the adhesive,
Extend the use scope of adhesive.While adhesive is improved to the binding strength of fiberglass, expand adhesive to other high scores
The adaptability of sub- material.Specifically diisocyanate is realized by improving the chemical bond of other each materials.
Adipic anhydride to polyisoprene rubber, can improve the life-span of polyisoprene rubber, reduce its aging speed.
Trimethylolpropane trimethacrylate can be to help adipic anhydride to polyisoprene rubber grafting, while energy
Shorten the hardening time of adhesive, improve bonding strength and quality.
Polytetrafluoroethylene (PTFE) can increase the plasticity of adhesive, improve the mobility during the use of adhesive,
It is easy to adhesive uniformly to smear, prevents the phenomenon of out-of-flatness.
Preferably, the adhesive also includes the polyamine epichlorohydrin resin that parts by weight are 3-5 parts.
Polyamine epichlorohydrin resin improves the heat resistance of adhesive, it is to avoid because temperature is too high or solar exposure
To the degradation with aging of adhesive.
Preferably, the adhesive also includes the N that parts by weight are 5-8 parts, N- diethyl-m-toluidines.N, N- diethyl
Base meta-aminotoluene can not only promote to improve the combination of the two main components of novolac epoxy resin and polyisoprene rubber, also
It can promote to form micro-elasticity between the two main components and between other compositions and combine, can so cause the glue after solidification
Glutinous agent can receive certain External force interference, it is to avoid when fiberglass is by intensity larger external force, cause fiberglass and internal decorative layer
Come off or partial exfoliation.
Preferably, the adhesive also includes the trimethylol-propane trimethacrylate that parts by weight are 3-6 parts.
Trimethylol-propane trimethacrylate can promote the combination of novolac epoxy resin and polyisoprene rubber,
Help form stable chemical bond therebetween, improve the compatibility of the two.
Preferably, the adhesive also includes the glass fibre that parts by weight are 2-7 parts.Improve the intensity of adhesive.
Preferably, the adhesive also includes the polysiloxane that parts by weight are 5-10 parts.
Polysiloxane can be protected to the adhesive before use, it is to avoid the performance reduction of adhesive, while just
Preserved in adhesive in canister, it is to avoid adhesive is bonded in container.
A kind of preparation method of GRP pipe adhesive, comprises the following steps, by novolac epoxy resin, polyisoprene
Rubber, triisopropanolamine, hydroxy-ethyl acrylate, trimethylolpropane trimethacrylate, butyl acetate, polyamideepichlorohydrin
Resin, N, N- diethyl-m-toluidines, trimethylol-propane trimethacrylate and glass fibre are added in reaction vessel,
Stir, stirring boils 2-3h at 55-60 DEG C, then adds adipic anhydride, diisocyanate, polytetrafluoroethylene (PTFE), ε-oneself
Lactone, and 1-1.5h is boiled at 60 DEG C, finally polysiloxane is added and is stirred continuously until cooling.
Compared with prior art, beneficial effect is the present invention：
1st, ageing-resistant, service life is longer；
2nd, the bond strength with fiberglass is high, and the adaptability to other high score subclasses for being used for fiberglass interior material is good；
3rd, there is preferable self-regulatory after hardening, can adapt to fiberglass and sticked together by external impacts without reducing
Property；
4th, the adhesion layer of small thickness can be not only formed, and preferable glue can be kept while larger adhesion layer is formed
Sticky energy；
5th, hardening time is shorter；
6th, in work progress, adhesive is preferable in the workability of glass fiber reinforced plastic surface, can be uniform to help rapid application.
