Abstract
The invention discloses a solid elastic ball, which is characterized in that it comprises spherical center made form foamed polyurethane and spherical emulsion bag covered out of outer wall of said polyurethane spherical center. The invention also discloses the process for preparing said solid elastic ball, comprising following steps: a. injecting polyurethane material into hollow emulsion bag; b. putting emulsion bag got in step 'a' into mould for foaming and shaping; c. shearing feed inlet of emulsion bag and getting product. The invention is characterized by increased combination degree of spherical center and said covered emulsion bag, even force of emulsion bag, uneasy for shape distortion, no delamination and coarse hand feeling, simple process, low energy consumption and no pollution.
Description
Technical field
The present invention relates to a kind of amusement and sports goods, relate in particular to a kind of solid elastic ball, the invention still further relates to the manufacture method of this solid elastic ball.
Background technology
Existing solid elastic ball, (be called for short: be that solid sphere is the most common PU) with polyurethane, its surface of this solid elastic ball does not generally coat other materials, half-finished polyurethane machine die of packing into is polished processing, form circular spheroid, advance to like the sphere brushing again and handle, last skinning dispatches from the factory.There is following deficiency in this manufacture method: one, process loaded down with trivial detailsly, and cause manufacturing cost higher, leftover pieces are not effectively recycled, so that waste of material is serious; Two, follow-up polishing and skinning mainly rely on manual manpower, inevitably produce a lot of uncertain factors, and the result makes problems such as easily foaming of product, delamination, feel be coarse; Three, because the restriction of own material and do not have the existence of integument, in the spheroid use, a large amount of gas leaks in the spheroid, screen resilience weakens, and shorten service time.
For this reason, application number is 00102761.1 Chinese patent application, (its publication number is: CN1262964A) to disclose " a kind of production technology of synthetic latex sponge soft ball ", its main feature is after natural rubber is carried out concentration, adds stabilizing agent, formaldehyde and compounding ingredient etc. and once finishes finished product.Application number is 200410004667.5 Chinese patent application, and (its publication number is: CN1666850A), its main feature is to finish fully combining of musculus cutaneus and internal layer under special mould to disclose a kind of " manufacture method of safe ball ".But above-mentioned two patent documentation manufacturing process are all complicated, input cost is also higher, and its manufacturing process does not break away from traditional category, all be to generate solid sphere earlier, then follow-up work again, the performance of product is subjected to follow-up man's activity very big, yielding in the use of product, the conjugation of the centre of sphere and top layer material is not good, causes the final products useful life very limited, so need further research and raising.
Summary of the invention
First technical problem to be solved by this invention provides a kind of centre of sphere and the integument conjugation is good, solid elastic ball cheap for manufacturing cost.
It is simple that second technical problem to be solved by this invention provides a kind of technological process, the manufacture method of solid elastic ball cheap for manufacturing cost.
The present invention solves the technical scheme that above-mentioned first technical problem adopts: this solid elastic ball, the spherical latex rubber bag that it is characterized in that comprising the polyurethane material centre of sphere of built-in foaming and be wrapped in polyurethane material centre of sphere outer wall is sprayed with polyurethane gloss varnish and the wear-resisting oil of polyurethane on this latex rubber bag outer wall.
The present invention solves above-mentioned second technical scheme that technical problem adopted: the manufacture method of this solid elastic ball is characterized in that comprising the steps: it is characterized in that the manufacture method of solid elastic ball comprising the steps:
A, in the spherical hollow latex rubber bag, inject polyurethane material;
B, the latex rubber bag that inside is marked with solid polyurethane material are put into mould, foaming and setting;
The charging aperture of c, the smooth latex rubber bag of pruning, finished product is at latex rubber bag spherical surface spray polyurethane gloss varnish and wear-resisting oil.
Its temperature of the polyurethane material that injects among the step a is preferably 20～30 ℃, and optimum temperature is 22～25 ℃.
Polyurethane material foaming and setting temperature is preferably 40～50 ℃ among the step b, and optimum temperature is 45 ℃.
Behind latex rubber bag spherical surface spray polyurethane gloss varnish and wear-resisting oil, also can comprise step: on the polyurethane material inlet, stick labeling among the step c.
Compared with prior art, the invention has the advantages that: owing to generate the integument latex rubber bag of solid elastic ball earlier, the reinject polyurethane material of the centre of sphere carries out foaming and setting to polyurethane material, again so the outer integument latex rubber bag conjugation of the centre of sphere and the centre of sphere greatly improves, latex rubber bag is stressed evenly, spheroid is not yielding, and the outer wall integrity of latex rubber bag is good simultaneously, bubbles, the phenomenon that delamination and feel are coarse etc. does not exist, and has improved the brightness and the wearability of this ball yet.Also be convenient to the spraying coating process on follow-up surface; Whole manufacture method is simple, and energy consumption is low, and is easy to operate, do not produce polluter, compliance with environmental protection requirements.

Fig. 1 is the cross-sectional view of solid elastic ball among the present invention.
Fig. 2 is an embodiment of the invention process flow diagram.
Fig. 3 is the view when injecting foaming and setting in polyurethane material and the mould in the latex rubber bag.
The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
With reference to figure 1, the solid elastic ball in the present embodiment comprises the PU material centre of sphere 2 of built-in foaming and is wrapped in the spherical latex rubber bag 1 of PU material centre of sphere outer wall, is brightness and the wearability that improves this ball, is sprayed with PU gloss varnish and the wear-resisting oil of PU on the described latex rubber bag outer wall.
Referring to figs. 2 and 3, the manufacture method of solid elastic ball comprises the steps: in the present embodiment
A, inject the PU materials with injection device 3 in the spherical hollow latex rubber bag, its temperature preferable range is 20～30 ℃;
B, the latex rubber bag that inside is marked with solid PU material are put into mould 4, foaming and setting 5～10 minutes, and its temperature preferable range is 40～50 ℃;
The charging aperture of c, the smooth latex rubber bag of pruning;
D, at latex rubber bag spherical surface spray PU gloss varnish and wear-resisting oil, improve the brightness and the wearability of this ball;
E, stick the trade mark labeling on PU material inlet, finished product packing dispatches from the factory.
Wherein the optimum temperature of step a is 22～25 ℃, and the optimum temperature of step b is 45 ℃.
