Abstract
The invention belongs to the technical field of the shoemaking industry, and particularly relates to a production process for forming a combined sole by using a rubber outer sole and a polyurethane middle sole. The production process comprises the following steps of: (1) producing a rubber outer sole mould sheet; (2) completely binding a pressed terylene fleece with the rubber outer sole mould sheet; (3) forming the rubber outer sole covered with the terylene fleece; and (4) injecting polyurethane solution to form the combined sole bound by using the rubber outer sole and the polyurethane middle sole. The various functional indexes of the combined sole produced by utilizing the method disclosed by the invention are far higher than the national standards.
Description
Technical field
The invention belongs to the shoemaking industry technical field, particularly relate to the manufacture craft that sole-shaped in a kind of rubber outsole and the polyurethane becomes the combination sole.
Background technology
At present, make in the technology at the bottom of the assembled shoe that sole combines in rubber outsole and the polyurethane, all need polish the rubber outsole; Afterwards to rubber outsole brush inorganic agent, oven dry again; Again to rubber outsole brush bonding agent, oven dry again; Putting into shoe-making die again injects at the bottom of the polyurethane formation assembled shoe.This manufacture craft is not only wasted resource, strengthens production cost, not environmental protection; And; The brush inorganic agent, the brush bonding agent, the time parameter of oven dry is difficult to control; Put into also very difficult control of speed that mould carries out the polyurethane injection; Adhesive strength does not reach specification requirement at the bottom of the assembled shoe that technology at the bottom of such shoemaking is made, and directly influences the quality of shoes, and this sole will come unglued after wearing a period of time probably.
Summary of the invention
The object of the invention just is to change the manufacture craft at the bottom of traditional manufacturing assembled shoe, removes unnecessary polishing, and the link of brush coating not only, is saved manpower, material resources and financial resources, and environmental protection more, and the quality of sole also accords with or surpasses national standard.
The objective of the invention is to realize like this: the manufacture craft that sole-shaped becomes to make up sole in rubber outsole and the polyurethane may further comprise the steps: (1) is cut into rubber outsole matrix with film for rubber according to the specification of rubber outsole; (2) polyester flannel is covered on the rubber outsole matrix, with being preheated to 140-160 ℃ of molding press it is suppressed, pressure is 50-60T, suppresses 3-5 minute, and polyester flannel and rubber outsole matrix fully are closely linked; (3) will be coated with the rubber outsole matrix cooling of polyester flannel after, it is carried out the pruning and the modification of periphery, form the rubber outsole that is coated with polyester flannel; (4) the rubber outsole is heated to 40-45 ℃ once more; Directly put into shoe-making die, be coated with one of polyester flannel and face up, directly be injected at polyester flannel on injector the polyurethane solutions that is preheated to 90-100 ℃; Then shoe-making die is closed and shut; Polyurethane solutions solidified after 8-10 minute, got final product depanning, formed at the bottom of the assembled shoe that sole combines in rubber outsole and the polyurethane.Described polyester flannel is a kind of commercially available dacron product.Described polyurethane is the abbreviation of polyurethanes, is a kind of known macromolecular material.
In the practice, utilize the inventive method, at the bottom of the assembled shoe of making, unstripped the opening of peel strength 119 (N/cm) (annotated: GB21148-2007 standard code peel strength (N/cm) >=59.This development has made full use of the advantage of sole in rubber outsole and the polyurethane, and each item functional parameter exceeds national standard far away.
Beneficial effect of the present invention: adopt this method, can save brush inorganic agent and brush adhesive two procedures; Simultaneously, the notes that use polyester flannel to do sole in rubber outsole and the polyurethane are carried body, do not contain Cr VI, and AZO is nontoxic, pollution-free.When the rubber outsole is made mechanical treatment, no dust.The rubber outsole does not use any chemical reagent and bonding agent, and it is nontoxic that the working site reaches, pollution-free, has guaranteed that the employee's is healthy.And technology of the present invention is convenient to operation more, not limited by temperature and time, does not receive the restriction of technological parameter.Need heat before putting into mould at the bottom of the rubber outsole, temperature is controlled at 40-45 ℃ and all conforms to quality requirements.The finished product qualification rate is very high at the bottom of the assembled shoe that this method is made, if go operation by operational procedure, defective work is generally less than 3 ‰.Simultaneously, more wear-resisting, (abrasion weight 2.2 grams of rubber outsole; Be higher than national standard) folding: deflect slight crack length 1.2mm 800,000 times.
The specific embodiment
Sole-shaped becomes the manufacture craft of combination sole in embodiment 1, rubber outsole and the polyurethane, and it is characterized in that: this manufacture craft may further comprise the steps: (1) is cut into rubber outsole matrix with film for rubber according to the specification of rubber outsole; (2) polyester flannel is covered on the rubber outsole matrix, with being preheated to 140-160 ℃ of molding press it is suppressed, pressure is 50-60T, suppresses 3-5 minute, and polyester flannel and rubber outsole matrix fully are closely linked; (3) will be coated with the rubber outsole matrix cooling of polyester flannel after, it is carried out the pruning and the modification of periphery, form the rubber outsole that is coated with polyester flannel; (4) the rubber outsole is heated to 40-45 ℃ once more; Directly put into shoe-making die, be coated with one of polyester flannel and face up, directly be injected at polyester flannel on injector the polyurethane solutions that is preheated to 90-100 ℃; Then shoe-making die is closed and shut; Polyurethane solutions solidified after 8-10 minute, got final product depanning, formed at the bottom of the assembled shoe that sole combines in rubber outsole and the polyurethane.Described polyester flannel is a kind of commercially available dacron product.Described polyurethane is the abbreviation of polyurethanes, is a kind of known macromolecular material.
