Abstract
The invention relates to the technical field of polymer materials, in particular to a formula of a rubber type vamp material and an improved preparation method thereof. The heat-preservation folding-resistance vamp material comprises the following components in percentage by weight: 50-60 percent of natural 3L rubber, 3-5 percent of accelerant, 40-45 percent of filling agent and 1.5-2 percent of curing agent. In the main formula, the accelerant is a mixture of an inorganic accelerant, an organic accelerant, polyethylene glycol, stearic acid, an antioxidant and a tackifier. In the invention, a vamp material is modified by adding accelerants with many properties into high-quality natural rubber and has the excellent performances of good elasticity, seawater immersion resistance, flexibility and folding resistance. The detection shows that the whole finished shoes made from the vamp material have the flexing angles of 45 degrees), and the vamps do not have cracks after circulating on the spherical surface for over one hundred thousand times.
Description
Technical field
The present invention relates to technical field of polymer materials, be specifically related to the improvement of rubber-like vamp material prescription and preparation method thereof.
Background technology
At present, the main raw that is used for the plastic cement vamp has rubber-like, thermoplastic elastomer class and Plastic, the vamp performance that various types of materials is made is different, such as its wearing quality of vamp and the frictional behaviour excellence made from rubber type of material, elastic reset is good, but its course of processing needs sulfuration, and its waste can't reclaim; To be that material has easy to process, technique is simple, waste products is recyclable and adopt thermoplastic elastomer, but wear resisting property is general.For this reason, industry is constantly improved the vamp material prescription again, seeks the material of the making sole of excellent property.
Summary of the invention
Technical problem to be solved by this invention is the rubber-like heat-preservation folding-resistance vamp material of the good and height folding trace of good heat preservation performance, elastic reset.
Another technical problem to be solved by this invention provides the preparation method of above-mentioned heat-preservation folding-resistance vamp material.
For solving the problems of the technologies described above, the prescription of heat-preservation folding-resistance vamp material of the present invention is as follows
1) natural 3L rubber 50～53%,
2) promotor 3～5%
3) weighting agent 40～45%
4) vulcanizing agent 1.5～2%
Promotor in the above-mentioned main formula is contained the mixture of inorganic accelerator, polyoxyethylene glycol, stearic acid, antioxidant and tackifier, and described inorganic accelerator is selected zinc oxide or magnesium oxide.Polyoxyethylene glycol is preferably used PEG4000, can increase oilness and the plasticity of rubber item, reduces the power consumption in the course of processing, prolongs the work-ing life of rubber item.
Antioxidant is selected antioxidant 1076 or plastics oxidation inhibitor LG103.Antioxidant can suppress or delay to mould the oxidative degradation of rubber and increase the service life, and this multiple oxidation inhibitor synergistic action effect of filling a prescription is better.Tackifier are for increasing the surface viscosity of product, and the tackifier of selecting those skilled in the art to commonly use have RX80 tackifier, tackifier A, tackifier RA-65, tackifier RA, and the tackifier effect is that various material combination are in an integral body.
Promotor is selected the auxiliary agent synergy multiple of different nature of anti-oxidant, activation and enhanced stability in the main formula, has the effect that activating component merges better, anti-aging, shortening curing time, reduces curing temperature, improves the physical and mechanical properties of product.
Preferably, the promotor in the above-mentioned main formula is further added organic promoter, and D promotor, M promotor and DM promotor are adopted in described organic short machine agent.Vulkacit D is mainly as moderate accelerator.Itself and altax are also with impelling the product endless vulcanization.Captax is ultra fast accelerator, has the effect of softening agent concurrently, and its sulfuration critical temperature is low, easily makes sizing material cause scorching.D promotor, M promotor and three kinds of accelerator combinations of DM promotor, effectively the adjustment vulcanization rate of product prevents ageing of rubber.
Weighting agent adopts not organism, inorganics, metal or the non-metal powder etc. that play undesirable action with material component all can realize the present invention, as selects in kaolin that those skilled in the art commonly use, diatomite, graphite, carbon black, aluminum oxide powder, glass powder, asbestos powder, mica powder, the stone flour one or both mixture.Preferably, can also add paraffin as weighting agent.
The sulphur S-80 that vulcanizing agent selects those skilled in the art to adopt.Sulphur S-80 effect is the rubber slaking.
The preparation method of above-mentioned heat-preservation folding-resistance vamp material is as follows:
1), according to formula rate, natural 3L rubber was smelt ripe glue in 15～25 minutes through mill;
2) add promotor in the ripe glue that is smelt, in proportion, weighting agent mixes stirring through mill, mixing temperature is controlled between 30 to 35 degree, churning time is 10～20 minutes, is smelt glue;
3), adding vulcanizing agent at last, uniform stirring made finished product glue in 2～6 minutes.
The present invention has following unusual effect compared to existing technology:
Major ingredient adopts natural 3L rubber in the material prescription of the present invention, has good elasticity, plasticity, Restoration, air permeability and water-absorbent, and is little take natural components as the main raw material environmental pollution, degrades easily and recycles.
Promotor has been screened multiple interactional rubber ingredients mix and match use in the material prescription of the present invention, polyoxyethylene glycol, stearic acid, antioxidant and tackifier, zinc oxide or magnesium oxide, D promotor, M promotor and DM promotor are jointly played activating component as promotor and are merged effect better, that shorten curing time, reduce curing temperature, improve the physical and mechanical properties of product, simultaneously, can also effectively adjust the product vulcanization rate, prevent ageing of rubber.
Select paraffin can so that the material slickness is good, prevent that prominent frost or white trace from appearring in material as weighting agent in this material prescription breakthroughly.
The promotor modification that vamp material of the present invention adopts the high-quality natural rubber to add multiple performance forms, and this vamp material has the excellent properties of good springiness, anti-sea water immersion and soft anti-folding line.The product shoes that vamp material of the present invention makes detects through Asia Britain Sha Chu (SATRA) technique center accredited laboratory, and whole footwear pliability (angle of deflection: 45 °) is: 100,000 circulation rear vamps are flawless on the sphere.
