96116347.X invention provides a kind of with the skid-resistant coating of polyurethane elastomer particle as main anti-skidding pellet.Realize in the following manner: a kind of elastic polyurethane skid-resistant coating, comprise first component polyurethane performed polymer, component B chainextender or solidifying agent and the third component solid grain is characterized in that described solid grain is the scrap stock that are ground into 10-80 purpose polyurethane product.Owing to be that a kind of elastomer coatings can not be widely used on some ground.
01122988.8 the present invention relates to glass manufacturing and processing industry, a kind of novel antiskid glass floor.The present invention is by the glass glaze in the surface printing layer of transparent of sheet glass, evenly sprays one deck anti-slip material again, is a kind of 80 orders～100 purpose glass microballons, through the pyroprocessing of annealing furnace, make glass microballon securely sintering on the surface of glass.Because the granularity of glass microballon causes harsh feeling, thereby has reached the skidproof effect of glass surface.Compared with the prior art, the present invention has security, outward appearance exquisiteness, advantage such as anti-skidding, transparent.
Usually be accompanied by the phenomenon of film coated surface foaming or pin hole in the flow leveling of polyurethane coating varnish, US-A-3743626 has told about a kind of azoles alkane and dihydric lower alkyl ester or poly alcohol acid and has reacted the generation that the mixture that makes suppresses bubble.
US-A-4296225 has told about at potential glue and has linked in the presence of the ethene polymers of unifying suppress the to film generation of bubble of synthetic poly-azoles alkane.
The improvement of the flow leveling of polyurethane coating varnish, EP-A-403921 discloses the poly aspartic acid biology as reactive thinner.These compounds contain the secondary amino group that forms urea groups with the isocyanic ester radical reaction.At present the shortcoming of known this reactive thinner is, in the coating composition content of polyisocyanates must improve greatly could with this reactive thinner complete reaction.The cost of this coating composition depends primarily on more expensive polyisocyanate component.
The adducts of BG1463944 Gong Kai oxazolidine derivative and vulcabond is bigger to environmental hazard as reactive thinner ， oxazolidine derivative.
Summary of the invention
The invention reside in provides a kind of coating varnish with the polyurethane material preparation, and has cling property.
The object of the present invention is to provide a kind of anti-skidding polyurethane coating, adopt water-retaining agent, reduced paint viscosity and formed from levelling, strong adhesion, wear resistance, weathering resistance, thermotolerance, chemical-resistant are good; And the surface of filming has the decorative pattern of rule, without any bubble or pin hole phenomenon.
The preparation method that provides a kind of anti-skidding polyurethane floor to varnish from levelling is provided another object of the present invention, and technology is simple, and is easy to implement the method, can be complementary with any color.
To achieve these goals, the present invention adopts following technical measures: at first prepare base polyurethane prepolymer for use as, then with the performed polymer modification, add a kind of imines water-retaining agent at last, can come into operation.
The present invention joins by following raw material system: toluene diisocynate TDI, polyethers N210, TriMethylolPropane(TMP), N-BUTYL ACETATE, acetone, dibutyl tin laurate, Benzoyl chloride, oxidation inhibitor, imines water-retaining agent, 1,2-propylene glycol.Wherein the weight proportion of performed polymer is: tolylene diisocyanate TDI 20-30 part, polyethers N21018-26 part, TriMethylolPropane(TMP) 3-10 part, N-BUTYL ACETATE 18-25 part, acetone 25-40 part, dibutyl tin laurate 0.05-1.0 part, Benzoyl chloride 0.001-0.5 part, oxidation inhibitor 0.01-0.5 part after the mixing, just obtains a kind of performed polymer.Getting above performed polymer and dimethylbenzene or N-BUTYL ACETATE or acetone mixes with the heating of imines water-retaining agent and promptly makes coating of the present invention, corresponding weight proportion is: above performed polymer 60-95 part, dimethylbenzene or N-BUTYL ACETATE or acetone 20-30 part, 1,2-propylene glycol 2-5 part, imines water-retaining agent 5-12 part, heating just obtains a kind of coating varnish after mixing.
Operational process of craft is as follows:
(1), N-BUTYL ACETATE or acetone or both mixtures, polyethers N210 are dewatered (this reactor must have thermometer, agitator, heating platform and nitrogen charging device) in reactor.Common heating reflux dewatering method temperature is controlled at about 90-100 ℃ 5-7 hour.Vacuum reflux dewatering temperature is controlled at 70-80 ℃, till not having condensate moisture to come out.
(2), TriMethylolPropane(TMP) is added in the reactor, temperature is controlled at 140-150 ℃, stirs, and temperature was controlled at 50-65 ℃ fully after the dehydration in 3-5 hour.
(3), be added dropwise to Benzoyl chloride, add tolylene diisocyanate (TDI) again, temperature is controlled at 60-80 ℃.Time, (this moment, temperature should be controlled in 80 ℃, and surpassing this temperature is color of soy sauce) added dibutyl tin laurate at last at 3-5 hour.
(4), partial solvent acetone, N-BUTYL ACETATE and moisture refluxed evaporator are gone out, temperature is controlled between 140-146 ℃,
(5), the performed polymer of high solids content is poured out reactor, under protection of nitrogen gas, in the Lacquered Tin Plate Can of packing into, temperature is controlled at 20-25 ℃, and is standby.
(6), with performed polymer, dimethylbenzene or N-BUTYL ACETATE or acetone, 1,2-propylene glycol, imines water-retaining agent add reactor in proportion, temperature is controlled at 90-110 ℃, keep 1-2 hour the cooling after, promptly be prepared into coating varnish.
The present invention compared with prior art has the following advantages and effect:
Solved the foaming phenomenon that the generation owing to carbon dioxide occurs up hill and dale, solved again simultaneously urethane from the levelling problem.The adding of imines water-retaining agent not only can be eliminated the environmental hazard of coating and improve the apparent of coating, also can strengthen the self-leveling energy of varnish as the reactive thinner of high solids coatings.1, the adding of 2-propylene glycol can be shortened the surface drying time of coating equally, and the length that how much can also control surface drying time according to its dosage helps the construction requirement under the various environment.Show according to the lab scale test-results: product of the present invention and traditional product relatively have following characteristics: surface luster is good, without any bubble or pin hole phenomenon; The well-regulated decorative pattern in surface can prevent to walk and slip; The instrument remarkable from the levelling effect, that zonule construction can be special is rolled with waddy and just can be made the automatic levelling of varnish; Technology of the present invention is simple, strong adhesion, and wear resistance, weathering resistance, thermotolerance, chemical resistant properties, the storage time is long; Varnish of the present invention can mate with the pigment of any color.
