Abstract
The invention discloses a method for solving a non-adhesion problem of a polypropylene injection-moulded shoe insole The method comprises the following steps of: before injection-moulding production each time, in an injection mould, preplacing an easily adhesive sheet on a part which is to be bonded subsequently of the outer surface of a polypropylene injection-moulded shoe insole; after forming moulding the polypropylene injection-moulded shoe insole by the injection mould, firmly attaching the preplaced easily adhesive sheet on the part which is to be bonded subsequently of the outer surface of the polypropylene injection-moulded shoe insole, to form an easily adhesive layer. According to the polypropylene injection-moulded shoe insole manufactured by the method disclosed by the invention, an adhesive layer is formed on the part which is to be bonded subsequently, so that the polypropylene injection-moulded shoe insole is adhesive, so that the following sole or product shoe can be manufactured by the conventional gluing way, and the non-adhesion problem of the polypropylene injection-moulded shoe insole is solved thoroughly.
Description
Technical field
The present invention relates to a kind of method that solves end non cohesive gel problem in the polypropylene injection moulded shoes.
Background technology
The end is a kind of common footwear material in the footwear, is an important component part of sole.In traditional footwear the end all be cut after adopting the couch board based sheet by the bonding stack of glue, polishing forms, and has the shortcoming such as manufacture craft is numerous and diverse, automaticity is not high, production efficiency low, cost of labor individual difference quite high, finished product is very big.
Existing a kind of advanced technologies of utilizing injection mold to produce the end in the injection moulded shoes can be full-automatic, the end in the high standardization ground production footwear, not only saves labour turnover, and improving production efficiency and product quality.
Polypropylene is commonly called as the PP plastics, is another resin kind with excellent comprehensive performance after nylon, and therefore, people extremely wish to be applied to the end in the injection moulded shoes.Yet, there is not polar group in the polypropylene molecule, surface energy is very low, it is a kind of extremely difficult sticking material, adopt polypropylene as the end in the injection moulded shoes of raw material production because its surface is difficult for viscose glue, cause to adopt in the polypropylene injection moulded shoes end to carry out the manufacturing of follow-up sole or product shoes by conventional adhesive means.
Summary of the invention
The purpose of this invention is to provide a kind of method that solves end non cohesive gel problem in the polypropylene injection moulded shoes so that in the polypropylene injection moulded shoes end can carry out by conventional adhesive means the manufacturing of follow-up sole or product shoes.
For achieving the above object, the technical solution used in the present invention is: a kind of method that solves end non cohesive gel problem in the polypropylene injection moulded shoes, before each time injection moulding is produced, in injection mold, the sheet material of easy viscose glue is placed at the follow-up position that needs viscose glue of end outer surface in the polypropylene injection moulded shoes in advance; , the sheet material of prepositioned easy viscose glue closely is attached to the outer surface follow-up position that needs viscose glue in the end in the polypropylene injection moulded shoes securely, forms the adhesive-layer of easy viscose glue at the end in through injection molded polypropylene injection moulded shoes.
The sheet material of described prepositioned easy viscose glue can be one chip, also can be the rear portion that is connected as a single entity, front portion and is divided into two half opening formula.
Described one chip sheet material can be acupuncture cotton, perhaps is fiberboard, perhaps is base plate in the paper pulp.
Described half opening formula sheet material is base plate in thicker fiberboard or the paper pulp.
Adopt the end in the polypropylene injection moulded shoes that method manufacturing of the present invention forms, at the follow-up position that needs viscose glue, be formed with adhesive-layer, but so that in the polypropylene injection moulded shoes end have viscosity, can carry out by conventional adhesive means the manufacturing of follow-up sole or product shoes, thoroughly solve the problem of end non cohesive gel in the polypropylene injection moulded shoes.
Description of drawings
Fig. 1 is the structural representation with end in the polypropylene injection moulded shoes of the easy viscose glue sheet material of one chip;
Fig. 2 is the structural representation with end in the polypropylene injection moulded shoes of the easy viscose glue sheet material of half opening formula.
Each label is respectively among the figure: the end in (1) polypropylene injection moulded shoes, (2) adhesive-layer.
The specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing:
Embodiment 1:
Referring to Fig. 1, a kind of method that solves end non cohesive gel problem in the polypropylene injection moulded shoes of the present invention, before each time injection moulding is produced, in injection mold, the follow-up position that needs viscose glue of the end 1 outer surface in the polypropylene injection moulded shoes, placing in advance thickness is the easy viscose glue sheet material of one chip of 0.5 millimeter acupuncture cotton material; , the sheet material of prepositioned easy viscose glue closely is attached to the outer surface follow-up position that needs viscose glue in the end 1 in the polypropylene injection moulded shoes securely, forms the adhesive-layer 2 of easy viscose glue at the end 1 in through injection molded polypropylene injection moulded shoes.
Embodiment 2:
Referring to Fig. 2, a kind of method that solves end non cohesive gel problem in the polypropylene injection moulded shoes of the present invention, before each time injection moulding is produced, in injection mold, the follow-up position that needs viscose glue of the end 1 outer surface in the polypropylene injection moulded shoes, placing in advance gross thickness is the easy viscose glue sheet material of half opening formula of 1.2 millimeters fiberboard material; , the sheet material of prepositioned easy viscose glue closely is attached to the outer surface follow-up position that needs viscose glue in the end 1 in the polypropylene injection moulded shoes securely, forms the adhesive-layer 2 of easy viscose glue at the end 1 in through injection molded polypropylene injection moulded shoes.The easy viscose glue sheet material of described half opening formula can in advance by cut open manually, perhaps utilize the fur edging machine that is used for the skiving cladding to carry out machine and automatically cut open.
Embodiment 3:
A kind of method that solves end non cohesive gel problem in the polypropylene injection moulded shoes of the present invention, before each time injection moulding is produced, in injection mold, the easy viscose glue sheet material of one chip of base plate material in 1 millimeter the paper pulp is placed thickness and is at the follow-up position that needs viscose glue of the end 1 outer surface in the polypropylene injection moulded shoes in advance; , the sheet material of prepositioned easy viscose glue closely is attached to the outer surface follow-up position that needs viscose glue in the end 1 in the polypropylene injection moulded shoes securely, forms the adhesive-layer 2 of easy viscose glue at the end 1 in through injection molded polypropylene injection moulded shoes.
In injection molded polypropylene injection moulded shoes in the process at the end, the polypropylene of molten state very easily enters the slit of base plate in pinprick cotton or fiberboard or the paper pulp under the environment of HTHP, behind the process cooling forming, in the polypropylene injection moulded shoes combine closely with easy viscose glue sheet material in the end, can in the polypropylene injection moulded shoes, form the adhesive-layer of closely firm easy viscose glue in the outer surface follow-up position of viscose glue that needs in the end, thereby solve the problem of end non cohesive gel in the polypropylene injection moulded shoes.
