Description
Technical field
The invention belongs to the polymer binder technical field, more particularly, is a kind of tackiness agent of light reflecting material special use.
Background technology
Traffic sign plays an important role in traffic administration and traffic safety.Traffic sign is of a great variety, but mostly is that night, display effect was relatively poor, was difficult to effectively try to forestall traffic accidents with common paint spraying board face in the past.Now, external traffic mark board face has generally used retroreflecting material.This sign shines by means of car bulb, makes the officer just can see pattern on the board face clearly outside hundreds of rice, helps safe driving greatly.In addition, facilities such as reflective police uniform, reflective isolation strip, reflector marker, reflector marking, reflective number plate are also promoted the use of.
The bonding of the light reflecting material and the sign board space of a whole page is the key link very in the production technique.With regard to homemade light reflecting material, directly the agglutinating technical problem does not also reach a standard (need 90 ℃ constant high temperature, flatten and paste), and in use is subjected to wind and weather aging very fast, is easy to come off, and will take place about 2 years seriously to fade, so that lost efficacy.At present the import light reflecting material begins to use on road sign, and adopted have Japan, an oriented reflection film produced in USA, can directly on the sign board space of a whole page, paste, and the processing that do not need to heat, technology is simple, and stability is good, and can reach more than 5 years work-ing life.
Patent No. CN95196332.5 is the special binder of reflecting material that contains polyether-polyurethane of Minnesota Mining and Manufacturing Company's invention, and its advantage is the goods softnesses, and water-wash resistance is good.But the tackiness agent ubiquity initial bonding strength that polyether(poly)urethane is made is poor, and it uses aromatic isocyanic ester more in addition, causes product that xanthochromia takes place under the Exposure to Sunlight condition easily.
Summary of the invention
The objective of the invention is to overcome the shortcoming of prior art, provide a kind of polyurethane binder of having strong adhesive power very between light reflecting material and the base material and preparation method thereof.
Tackiness agent of the present invention contains A component and B component, and the weight ratio between them is A: B=20: 3, wherein:
(1) composition of A component and weight percentage thereof: polyester polyol 30-50%, solvent 40-60%, isocyanic ester 5-15%, coupling agent 0.1-1%, catalyzer 0.02-0.06%, antiager 0.02-0.06%.
Described polyester polyol comprises that poly-m-phthalic acid ethylene glycol-neopentyl glycol esterdiol, poly-hexanodioic acid neopentyl glycol-1,6 hexylene glycol esterdiol, poly-hexanodioic acid 1,2 propylene glycol-sebacic acid 1,4 butanediol ester glycol are at interior any.
Described isocyanide ester ester comprises any aliphatic diisocyanate of terephthalylidene vulcabond (XDI), isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HDI).
Described catalyzer comprises any amine or the tin compound of triethylamine, triethylene diamine, stannous octoate, dibutyl tin laurate.
Described coupling agent comprises any organic silicide of γ-glycidoxy propyl-triethoxysilicane (KH560), vinyl silane tri-butyl peroxide (KH590), γ-methacrylic acid propyl trimethoxy silicane (KH570), vinyltriethoxysilane (A-151).
Described antiager comprises four, and [methylene radical-3-(3,5-di-t-butyl-4-hydroxyl-phenyl) propionic ester] methane (antioxidant 1010), Octabenzone (UV531), 2-(2 '-hydroxyl-3 ', 5 ' two (a, a-dimethyl benzyl) phenyl) benzene a pair of horses going side by side triazole (UV234) is at interior any.
(2) composition of B component and weight percentage thereof:
Isocyanic ester 40-60%, low molecular polylol 10-30%, solvent 25-40%.
Described isocyanic ester comprises any of terephthalylidene vulcabond (XDI), isophorone diisocyanate (IPDI), hexamethylene diisocyanate (HDI).
Described low molecular polylol comprises that TriMethylolPropane(TMP), Viscotrol C, glycol ether, 1,3 propylene glycol are at interior any.
Described solvent comprises any of acetone, toluene, methylethylketone, ethyl acetate.
The preparation method of tackiness agent of the present invention comprises following process:
(1) preparation A component: polyester polyol, solvent, isocyanic ester are mixed in proportion and are warming up to 75-85 ℃, reacted 1-2 hour, add catalyzer after reducing to 60-70 ℃ again, be warming up to 75-85 ℃, continue reaction 1-2 hour, reduce to room temperature, to record viscosity be 2500-5000mpa.s, when solid content is 53-57%, add coupling agent and antiager, mixed 30-40 minute, get the A component;
(2) preparation B component: with isocyanic ester and solvent and be heated to 40-45 ℃ and add low molecular polylol again after mixing, be heated to 70-80 ℃, reacted 2-3 hour, reduce to room temperature, recording viscosity is 1500-2500mpa.s, and solid content is 68-72%, promptly gets the B component;
(3) preparation tackiness agent: the weight ratio of the B component that A component that step (1) is made and step (2) make is that 20: 3 amount is mixed, and stirs and promptly gets required tackiness agent.
The using method of tackiness agent of the present invention:
(1) at first reflective glass beads is pressed together on the polyethylene film under 120 ℃ of conditions, and at pane microbead surface spraying aluminium coated, thickness is 1-3 μ m;
(2) then tackiness agent is evenly applied on the reflective base material, its thickness is 10-20 μ m, 80-100 ℃ of P baking oven thorough drying;
(3) polyethylene film that will be pressed with the glass microballon face and the reflective base material pressing that scribbles tackiness agent, slaking is 24 hours under 60-80 ℃ of condition, takes polyethylene film off and gets final product.
Described reflective base material nylon, terylene, rubber, leather are at interior any.
Advantage of the present invention and effect:
Special binder of reflecting material of the present invention is the response type two component polyurethane adhesive, has good bond properties and ageing-resistant performance, and colloid is light yellow transparent liquid.To excellent initial bonding strength is arranged between light reflecting material such as glass microballon and the base material, the finished product of making can be anti-60 ℃ and 90 ℃ of washings more than 10 hours, do not worn out by wind and weather and do not come off.The xanthochromia phenomenon under sun direct irradiation, does not take place in 1 year in the reflective glued membrane of making.Be used for reflective police uniform, soft high temperature resistant water washing, reflecting effect is splendid.Facts have proved that this product has not only remedied the shortcoming of homemade light reflecting material with tackiness agent, and contrast import tackiness agent has cost advantage low, easy to use.From having solved the problem of domestic high-grade light reflecting material tackiness agent dependence on import to a great extent, filled up domestic blank.
