Accompanying drawing explanation
Fig. 1 is environment-friendlyleather leather pulp belt material production craft step flow chart in the present invention.
Fig. 2 is the production technological process of vegetable tanning leather fiber in the present invention.
Detailed description of the invention
For making object of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment.
The invention discloses a kind of environment-friendlyleather leather pulp belt material, comprise vegetable tanning leather fiber, tannin extract, sulfited fish oil, sodium bicarbonate, acrylic resin, natural emulsion and toner, above-mentioned each component ratio is followed successively by 100:5:10:5:8:56:4, and wherein said vegetable tanning leather fiber is dry state (not having moisture) vegetable tanning leather fiber.But in actual production, consider that the vegetable tanning leather fiber of complete dry state is difficult to obtain, therefore in the present invention, the ratio of vegetable tanning leather fiber can be chosen between 94-106.
In actual production, toner comprises iron oxide yellow and iron oxide red, the color of toner major effect finished product, specifically can the ratio of selective oxidation iron oxide yellow and iron oxide red according to actual needs, and in the present embodiment, the ratio of iron oxide yellow and iron oxide red is 17:3.
In actual production, natural emulsion selects gel content to be 60% high ammonia concentrated natural latex.
The preparation method that the invention also discloses vegetable tanning leather fiber is as follows, and its idiographic flow, see Fig. 2, comprises the following steps:
Step a: get vegetable tanning leather material, by Impurity removal wherein, removes the diaphragm on vegetable tanning leather material surface simultaneously;
Step b: carry out beating angle to vegetable tanning leather material, by broken for vegetable tanning leather material frustillatum, then sieves, and continues to carry out playing angle, screening to the vegetable tanning leather material not by screen cloth;
Step c: the vegetable tanning leather material through screening is carried out separating twice, carries out regrading by the material after pulverizing, continues to pulverize the material not by regrading, regrading;
Steps d: the vegetable tanning leather fiber obtained after collecting regrading, collects the dust produced in screening and regrading process simultaneously.
In actual production, vegetable tanning leather material in step a is the leftover bits after manufacturing leathercraft, impurity wherein must be removed before carrying out that angle technique is beaten to vegetable tanning leather material, as the scraps of paper, strap, variegated skin bit, not so can affect the purity of the vegetable tanning leather fiber finally obtained, thus affect the quality of finished belt.
The invention also discloses the production technology of environment-friendlyleather leather pulp belt material, as shown in Figure 1, comprise the following steps:
Steps A: get vegetable tanning leather fiber, add water slurrying in vegetable tanning leather fiber, obtains fibre stuff, refine fibre stuff;
Step B: add tannin extract, sulfited fish oil, sodium bicarbonate, acrylic resin and toner in the fibre stuff after fine grinding, stir and obtain belt slurry; Get natural emulsion to add water obtained glue simultaneously, for subsequent use;
Step C: by belt slurry and glue mixed-forming, then carry out suction filtration, oven dry, rolling, bundling and classification, obtain belt finished product.Wherein, the step such as suction filtration, oven dry, rolling, bundling and classification is conventional leather pulp belt material production technology.
In actual production, the ratio of vegetable tanning leather fiber and water is 3:97, this is because fibre concentration is too high easily cause poor fluidity, is unfavorable for the operations such as oiling, dyeing, filling; Fibre concentration is too low, easily causes refining effect poor, and during production, wave is large, and molding thickness is uneven.
In actual production, the ratio of natural emulsion and water is 7:100, if natural emulsion content is lower than this ratio, then the poor mechanical property of product, does not meet production requirement; If natural emulsion content is higher than this ratio, then cost is large, is unfavorable for large-scale production.
The invention provides a kind of environment-friendlyleather leather pulp belt material and production technology thereof, vegetable tanning leather fiber is made by utilizing the discarded scrap material in leather, recycling vegetable tanning leather fiber coordinates other components to be made into strapping according to certain ratio, achieve the technique effect that ox-hide leftover pieces are discarded in recycle, and make by production technology of the present invention the strapping tensile strength obtained and be greater than 10N/mm
2, percentage elongation is greater than 20%, and mechanical property is better than the corium of condition of equivalent thickness, but price only has 50% of corium, is particularly suitable for producing establishment belt, the also purposes of alternative some dermis.Leather pulp belt material production technology provided by the invention, the vegetable tanning leather adopted, not containing heavy metal chromium, does not add harmful chemical simultaneously in process of production, and environmental protection is practical, is specially adapted to large-scale production.
Should be understood that, application of the present invention is not limited to above-mentioned citing, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
