Abstract
The invention discloses a high-sealing bonding resin for glass and metal, which is characterized by comprising the following constituents in parts by weight: 100 parts of modified polyvinylalcohol tripolyphosphate, 20-75 parts of calcium carbonate, 10-30 parts of butyl rubber, 5-15 parts of rosin resin, 15-45 parts of terpene resin and 50-100 parts of acetone. According to the invention, via modification for polyvinyl alcohol, the compatibility of polyvinyl alcohol with other resins is enhanced; simultaneously, due to a phosphate group, the bonding strength of polyvinyl alcohol with metal is enhanced, and unreacted hydroxyl in polyvinyl alcohol can form strong chemical bonds or hydrogen bonds on the surfaces of glass and metal. Via the addition of silica fume, the cost of the bonding resin is reduced; and simultaneously, the tensile strength of the bonding resin can be enhanced, and great leakproofness is achieved.
Description
Technical field
The present invention relates to the binding resin for glass and metal high sealing.
Background technology
It is very important that glass is directly bonded on metal, and metallic surface and glass surface are all difficult to bonding.
Be used for the bonding of glass and metal, and have the material of high sealing, be generally silicone sealant, but this material, taking organosilicon as main body, has good elasticity, mechanical property is poor, can only be applied in stressed less field.Silicone sealant major part is single-component or two component, and single-component curing speed is slow, and two components need construction technology more complicated.When silicone seal adhesive curing, can produce a large amount of small molecules, after life-time service, these small molecules can migrate to surface of pressure-sensitive adhesive, and bonding substrates is had to corrosive nature.
Summary of the invention
The object of this invention is to provide the binding resin for glass and metal high sealing.
For achieving the above object, for the binding resin of glass and metal high sealing, the component that comprises following weight part:
Tripolyphosphate modified polyvinylalcohol resin 100
Calcium carbonate 20-75
Isoprene-isobutylene rubber 10-30
Gum Rosin 5-15
Terpine resin 15-45
Acetone 50-100
The preparation method of tripolyphosphate modified polyvinylalcohol resin is: polyvinyl alcohol is soluble in water, under agitation add tripolyphosphate and catalyst sulfuric acid, at the temperature of 35～50 DEG C, carry out esterification, the product of generation obtains tripolyphosphate modified polyvinylalcohol resin through washing, centrifugal drying.
Be used for the preparation method of the binding resin of glass and metal high sealing:
In acetone soln, add successively tripolyphosphate modified polyvinylalcohol resin, isoprene-isobutylene rubber, Gum Rosin, terpine resin, in high speed dispersor, be dispersed to all resins and dissolve completely, obtain base-material.Base-material is mixed with calcium carbonate, and grinding distribution on three-roller, obtains the binding resin for glass and metal high sealing.
Beneficial effect of the present invention:
The present invention is by the modification to polyvinyl alcohol, strengthen the consistency of itself and other resin, simultaneously because phosphate group, strengthen and the cohesive strength of metal, in polyvinyl alcohol, unreacted hydroxyl can form stronger chemical bond or hydrogen bond in glass, metallic surface.
By adding SILICA FUME, reduce the cost of binding resin, can improve the tensile strength of binding resin simultaneously, there is good stopping property simultaneously.
