Abstract
The invention relates to the technical field of preparation of shoes and provides rubber foamed shoes which are skid-proof on water, ice and oil, light in mass, soft in texture, high in adhesive force of shoe soles and shoe uppers, good in elasticity, free of use of a glue adhesive, environmentally friendly, unlikely to deform, good in springback effect and high temperature-resisting. Each shoe comprises a shoe sole and a shoe upper which is arranged on the shoe sole, wherein each shoe sole is prepared from the following raw materials in parts by weight: 250-300 parts of natural rubber, 600-700 parts of rock flour, 60-80 parts of zinc oxide, 3-5 parts of stearic acid, 5-10 parts of foaming agent, 4-6 parts of sulfur, 3-5 parts of an accelerator D, 3-5 parts of a rubber accelerator DM, 8-10 parts of an anti-ageing agent and 10-11 parts of ointment. The invention also provides a preparation method of the rubber foamed shoes, and the preparation method has the advantages of being simple in steps, saving time and greatly lowering the economic cost.
Description
Technical field
The present invention relates to a kind of shoes, relate in particular to a kind of rubber pange footwear and preparation method thereof.
Background technology
Footwear on existing market, roughly by the large end, in the end and upper of a shoe three parts form, its making processes is generally first to make respectively the large end, the middle end and upper of a shoe, with glue plastering agent, the large end and the middle end and the middle end and upper of a shoe are bonded together and form complete shoes again, the middle end, also can be connected by sewing type with upper of a shoe.Traditional shoe-making process is cumbersome, need to use glue plastering agent, the volatilization of glue plastering agent produces obnoxious flavour, health to human body threatens, and easy contaminate environment, not environmental protection, in addition, traditional shoe-making process required time is longer, and according to statistics, the shoes that will produce 2500 pairs for one day at least need 80 workmans.Adopt footwear that traditional shoe-making process makes in use for some time vamp and sole easily there is degumming phenomenon, at the lower weather of temperature, even easily there is the situation of fracture, quality is not good, and weight is heavier, and the comfort of dress is inadequate, resilience weak effect, can not meet people's demand.
Summary of the invention
Therefore, for above content, the invention provides that a kind of water resistant is sliding, anti-ice is sliding, anti-cunning, quality is light, material is soft, sole and upper of a shoe bounding force by force, good springiness, do not need to use glue plastering agent, environmental protection, not yielding, resilience is effective, resistant to elevated temperatures rubber pange footwear, and the preparation method that a kind of these rubber pange footwear are provided, this preparation method's step is simple, save time, and can save larger Financial cost.
For achieving the above object, the present invention is achieved by the following technical solutions: a kind of rubber pange footwear, and comprise sole and be located at the upper of a shoe on sole, described sole comprises the starting material of following weight part:
250～300 parts of natural rubbers
600～700 parts of stone flours
60～80 parts, zinc oxide
3～5 parts of stearic acid
5～10 parts of whipping agents
4～6 parts, sulphur
3～5 parts of vulkacit Ds
Rubber accelerator DM3～5 part
8～10 parts, anti-aging agent
10～11 parts of ointment.
Further improve and be: described sole comprises the starting material of following weight part:
270～290 parts of natural rubbers
650～690 parts of stone flours
70～78 parts, zinc oxide
4～5 parts of stearic acid
7～9 parts of whipping agents
5～6 parts, sulphur
4～5 parts of vulkacit Ds
Rubber accelerator DM4～5 part
9～10 parts, anti-aging agent
10.5～11 parts of ointment.
A preparation method for rubber pange footwear, comprises the following steps:
(1) prepare rubber pange sheet: the starting material of the sole of each weight part claimed in claim 1 are put into rubber mixing machine mixing, obtain rubber pange sheet;
(2) prepare patrix, bed die and shoe last;
(3) rubber pange sheet step (1) being made is put into bed die, shoe last is fixed on to the corresponding position of patrix, at shoe last, puts upper of a shoe outward, foaming at 150～170 ℃, sizing;
(4) delasting head, the demoulding: take out shoe last, patrix and bed die, make integrated rubber pange footwear.
Further improve and be: in described step (1), mixing time is 30～35min.
Further improve and be: the foaming and setting time in described step (3) is 7～10min.
By adopting aforementioned techniques scheme, the invention has the beneficial effects as follows: the step of preparation process of the integrated rubber pange footwear of the present invention is simple, easy to operate, save time, adopt technique of the present invention, in one day, produce 2500 pairs of shoes and only need 20 workmans, compare traditional technique and saved the workman of 60 left and right, saved largely manpower, for enterprise has saved a large amount of Financial cost.The formula of soles environmental protection of rubber pange footwear of the present invention, the sole resilience that adopts such formula to make is effective, has memory effect, after turnover, can return to original shape, bonding force is strong, with upper of a shoe moulding after, the adhesive effect between sole and upper of a shoe is good, is difficult for peeling off, do not need to use glue, free from environmental pollution, simultaneously owing to not using glue, the injury of effectively having avoided glue volatilization to produce human body; In addition, shoes are at high temperature dressed and are difficult for the phenomenon come unstuck, and the anti-neatly of sole, ice slipping prevention, prevent that cunning effect is good, the shoes overall weight making is light, dresses comfortablely, at wintry weather, comparatively dresses severe cold in the situation that, be not easy to rupture, the cold tolerance of shoes is better.
