Description
Technical field
The invention belongs to building material technical field, relate to a kind of wet solid type polyurethane adhesive for elastic adhesives such as metal, pottery, stone material and Kimuras and preparation method thereof.
Background technology
Tackiness agent is the material of filling space such as hole, joint, seam etc. and bonding effect being arranged filling the basic unit interface, and it mainly comprises: organosilicon (comprising modified organic silicon) class, poly-hydrogen ester class, thiorubber class, esters of acrylic acid, SBR rubber-like, butyl type rubber, pitch, oiliness caulk compound class etc.And be used to fill must stand to shake or rising-heat contracting-cold etc. due to have retractility gap, must adopt elastic attachment adhesive.Elastic attachment adhesive is by bonding and two kinds of products that function rolls into one of sealing.Wherein the high-grade elastic attachment adhesive of three classes of better performances is respectively organic silicon adhesive, polysulfide sealant and polyurethane adhesive.In recent years, the application of elastic attachment adhesive in much industry, the civil areas such as building, building, automobile, boats and ships, electric communication is more and more extensive.In above-mentioned elastic attachment adhesive, polyurethane adhesive is with the fastest developing speed, and demand increases gradually, is because it has good performance.The characteristics of polyurethane adhesive have: the wear resistance that (1) is good; (2) low-temperature pliability; (3) the performance adjustable extent is wide; (4) physical strength is large; (5) cementability is good; (6) good springiness, have good Restoration, can be suitable for dynamic seam; (7) good weatherability, be 15-20 work-ing life; (8) oil-proofness is good; (9) anti-biological aging; (10) moderate cost.When monocomponent polyurethane adhesive was bonding, its body intensity was low or unit elongation is low, and solidification rate is low, had affected effect or the work efficiency of monocomponent polyurethane adhesive.
Summary of the invention
Main purpose of the present invention is to overcome the technological deficiency that existing monocomponent polyurethane adhesive exists, provide body intensity and unit elongation higher, and have at low temperatures high solidification rate, thereby more be suitable for practical a kind of new polyurethane adhesive and preparation method thereof.
The present invention is achieved in that
A kind of wet solid type polyurethane adhesive, comprise that polyether glycol, terpene phenolic resin and dibutyl tin laurate make performed polymer, add linking agent, filler and mill base to make polyurethane adhesive, component and parts by weight are: 66～68 parts of polyether glycols (M=2800), 6.6～6.8 parts of terpene phenolic resins, 0.12～0.14 part of stannous octoate, 0.66～0.68 part of dibutyl tin laurate, 3.0～3.6 parts of linking agents, 22～23 parts of fillers and mill base are appropriate.
Above-described wet solid type polyurethane adhesive, component and parts by weight comprise: 67 parts of polyether glycols (M=2800), 6.7 parts of terpene phenolic resins, 0.13 part of stannous octoate, 0.67 part of dibutyl tin laurate, 3.3 parts of linking agents, 16.7 parts of talcum powder, 6 parts of kaolin and mill base are appropriate.
Above-described linking agent, comprise the mixture of '-diphenylmethane diisocyanate (MDI) and tolylene diisocyanate (TDI), and the weight ratio of MDI and TDI is 1: 1.
Above-described filler, the component comprised and parts by weight: 16.0～17.5 parts of talcum powder, 5.5～6.5 parts of kaolin.
The preparation method of this wet solid type polyurethane adhesive comprises the following steps:
(1) '-diphenylmethane diisocyanate (MDI), tolylene diisocyanate (TDI), stannous octoate and talcum powder are added in reactor, be uniformly mixed, controlling temperature is 40 ℃, and it is standby that the time is that 45～65min makes mixture;
(2) polyether glycol, terpene phenolic resin, dibutyl tin laurate and kaolin are dropped in reactor, be uniformly mixed, controlling temperature is 40 ℃, and the time is that 50～70min makes performed polymer;
(3) in performed polymer, controlling temperature is 40 ℃, stirs, and in 3h, slowly adds mixture, and adds appropriate mill base to make wet solid type polyurethane adhesive every 1h.
Advantage of the present invention and positively effect:
Product of the present invention has overcome existing monocomponent polyurethane adhesive and has existed when bonding, its body intensity is low or unit elongation is low, solidification rate is low, the effect of monocomponent polyurethane adhesive or the technological deficiency of work efficiency have been affected, reach body intensity and unit elongation higher, and have at low temperatures high solidification rate.
Product of the present invention is applicable under the environment of the gentle high low humidity of height and the elastic adhesive of other strong mechanical performance, as bonding as metal, timber, stone material etc., especially is adapted at the use in toilet and kitchen.
