Abstract
The invention relates to bowling bowl and its preparation method. The bowl comprises inner bag compact sphere composed by UP and all kind stuffings, and outer shell of polyurethane micropore elastic body molded by isocyanate and polyether or PE mixture. When putting inner bag into mould, it just need to pour the mixture liquid of outer shell into mould and solidify. The product has well performance and fits to all alleys.
Description
Technical field: the present invention relates to bowling and bowls manufacture method.
Background technology: the two component bowling shell material of using both at home and abroad need be carried out polymerization respectively at present, Chinese patent ZL98125638.4 has introduced " a kind of polyurethane bowling ball and manufacture method thereof ", its complex process, raw material needs high temperature to preserve during the bowling cast, want hot setting a few hours after the cast, energy consumption is big.
Summary of the invention: the purpose of this invention is to provide a kind of bowling and manufacture method thereof, solve the problem of original complicated process of preparation, reduce hardening time, cut down the consumption of energy.Bowling of the present invention realizes by following technical scheme.Polyurethane bowling ball of the present invention is made up of inner bag and shell, shell is by two kinds of formulated microporous polyurethane elastomers of mother liquor of A, B, the A mother liquor is polyethers or polyesters polyalcohol and the small molecular alcohol compounds that contains active hydrogen and the mixture of relevant auxiliary agent, the B mother liquor is the modified isocyanate compound, and isocyano-content is 25-35% in the B mother liquor.Inner bag is the closely knit spheroid that is solidified into after unsaturated polyester (UP) and various filler mix, and unsaturated polyester (UP) is that phthalic acid is along the class D unsaturated polyester (UP).
The weight ratio of A, B or C, D mother liquor can be 100/30-100 in the such scheme, and wherein preferred proportion is 100/50-80.
Inner bag can add filler in the such scheme: talcum powder, barium sulfate, glass microballoon, iron powder, titanium valve are regulated weight, can use above composition separately, use also capable of being combined.
Bowling manufacture method of the present invention may further comprise the steps:
(1) inner bag preparation: phthalic acid mixes along class D unsaturated polyester (UP) and various filler, the filler adding proportion is the 5-40% of phthalic acid along class D unsaturated polyester (UP) weight, the promoter (cobalt naphthenate) and the initator (methyl ethyl ketone peroxide) that add weight polyester 0.2%-2% make its curing, are made into inner bag;
(2) inner bag is inserted in the mould, A, B mother liquor are mixed being poured into mould, solidified 1-20 minute;
(3) demoulding, room temperature was placed 12-24 hour.
(4) turning and sanding and polishing.
For the balance center of gravity, the inner bag opposite shell can adopt eccentric design, and inner bag also can be designed to two formulas, three formulas or four formulas.
The invention has the beneficial effects as follows: the raw material preparation that the present invention uses is simple, and the raw material ambient operation got final product when bowling was made, and is simple for process, excellent product performance.The bowls special feature of the present invention is that the bowling shell is a microporous polyurethane elastomer, when the bowling lanes oil mass more for a long time, this ball can absorb oil to guarantee frictional force suitable between ball and alley; When bowling lanes oil mass seldom the time, this ball can discharge the oil of absorption to guarantee frictional force suitable between ball and alley, and at different alleys, this ball all has good adaptive capacity, and this ball has robust characteristics.
The specific embodiment:
Embodiment 1:
Accounting for the poly-adipic acid diethyl alcohol ester (Mn=1000) of A mother liquor 95% and weight with weight, to account for A mother liquor 5% ethylene glycol mixing and stirring be the A mother liquor, and the B mother liquor is modification MDI (methyl diphenylene diisocyanate) liquid.The inner bag preparation: phthalic acid mixes along class D unsaturated polyester (UP) and various filler, filler is talcum powder, barium sulfate, glass microballoon, three's ratio is 1: 1: 1, addition is a weight polyester 8%, the promoter (cobalt naphthenate) and 0.4% initator (methyl ethyl ketone peroxide) that add weight polyester 0.2% make its curing, are made into inner bag.
Inner bag is inserted in the mould, and it is even that A, B mother liquor are added blend of colors in 100: 80 ratio, vacuumizes and remove bubble, mixed liquor is poured into mould, solidified 20 minutes, normal temperature cure is 24 hours after the demoulding, becomes the finished product bowling through lathe, polishing, polishing.
Embodiment 2:
Account for A mother liquor 98% polycaprolactone (Mn=1500) and weight accounts for A mother liquor 2%1 with weight, 4-butanediol mixing and stirring is the A mother liquor, and the B mother liquor is thick MDI (methyl diphenylene diisocyanate) liquid.The inner bag preparation: phthalic acid mixes along class D unsaturated polyester (UP) and various filler, filler is a glass microballoon, addition is a weight polyester 15%, and the promoter (cobalt naphthenate) and 1% initator (methyl ethyl ketone peroxide) that add weight polyester 0.8% make its curing, are made into inner bag.
Inner bag is inserted in the mould, and it is even that A, B mother liquor are added blend of colors in 100: 60 ratio, vacuumizes and remove bubble, mixed liquor is poured into mould, solidified 10 minutes, normal temperature cure is 24 hours after the demoulding, becomes the finished product bowling through lathe, polishing, polishing.
Embodiment 3:
Accounting for A mother liquor 90% polypropylene glycol (Mn=1000) and weight with weight, to account for A mother liquor 10% diethylene glycol mixing and stirring be the A mother liquor, and the B mother liquor is modification MDI (methyl diphenylene diisocyanate) liquid.The inner bag preparation: phthalic acid mixes along class D unsaturated polyester (UP) and various filler, filler is iron powder, titanium valve, both ratios 1: 1, addition is a weight polyester 25%, the promoter (cobalt naphthenate) and 1.5% initator (methyl ethyl ketone peroxide) that add weight polyester 1.4% make its curing, are made into inner bag.
