Abstract
The invention relates to a material for making a boot sole, and concretely relates to a puncture resistant boot sole material. The puncture resistant boot sole material comprises, by weight, 20-60 parts of natural rubber, 40-20 parts of chloroprene rubber, 40-20 parts of styrene butadiene rubber, 1.2-2.0 parts of sulfur, 0.3-0.8 parts of an accelerant DM, 0.3-1.0 part of an accelerant M, 5.0-7.0 parts of zinc oxide, 1.0-2.5 parts of stearic acid, 25-35 parts of high-wear-resistance carbon black, 0.8-1.5 parts of an antioxidant D, 1.0-2.0 parts of an antioxidant 4010 and 1.5-2.5 parts of magnesium oxide. The puncture resistant boot sole material has a reasonable design, and is designed through a ternary combination method of the chloroprene rubber, the natural rubber and the styrene butadiene rubber, so the molecular chain slip and fracture phenomena of the sole material are difficult when a sole meets a sharp object, thereby the puncture resistance of the boot sole is substantially improved.
Description
Technical field
The present invention relates to manufacture the material at the bottom of boots, be specially a kind of anti-puncture boots bottom material.
Background technology
Along with the development of guard technology; all kinds of footwears (boots) are of a great variety; various functions are also day by day perfect; particularly some special occasions; as fire protection sector need to have the functions such as fire-retardant, corrosion-resistant, anti-skidding, anti-puncture, for military Protective Boots (footwear), to possess protection to military toxic agent, high-risk chemical, there is fire-retardant, anti-puncture ability simultaneously.No matter for military or civilian, at the bottom of boots, anti-puncture performance is one of important use properties of boots (footwear).If be not highly resistant to the piercing through of sharp object, bursting, poisonous, hazardous and noxious substances can be infiltrated in boots (footwear), and human body is produced to harm.
When contact sharp object, very easily there is slippage, the fracture of molecular chain in boots bottom material, boots (footwear) end is pierced.In order to strengthen the anti-puncture performance at the bottom of boots, general by increasing the anti-puncture layer of metal, ensure the puncture resistance at the bottom of boots.Adopt which when effectively improving anti-puncture performance, also bring the problem of three aspects:: the one, weight metal is large, increases the physiological stress of human body; The 2nd, the flexibility at boots (footwear) end is poor; The 3rd, metal level easily transmits surface temperature, in high temperature or microthermal climate, easily worsens the interior temperature and humidity of boots (footwear), and comfortableness is poor.
Summary of the invention
The present invention adds metal to put the problems referred to above that puncture layer and exist in order to solve in boots bottom material, and a kind of anti-puncture boots bottom material is provided.
The present invention adopts following technical scheme to realize:
A kind of anti-puncture boots bottom material, is comprised of the raw material of following parts by weight:
Natural rubber: 20～60; Chloroprene rubber: 40～20; Styrene-butadiene rubber(SBR): 40～20; Sulfur: 1.2～2.0; Altax: 0.3～0.8; Captax: 0.3～1.0; Zinc oxide: 5.0～7.0; Stearic acid: 1.0～2.5; High abrasion carbon black: 25～35; Antioxidant D: 0.8～1.5; Antioxidant 4010: 1.0～2.0; Magnesium oxide: 1.5～2.5.
The preparation method of above-mentioned anti-puncture boots bottom material is as follows:
(1), by formula rate, weigh the consumption of various rubber and Synergist S-421 95;
(2), use mill to carry out mixing: natural rubber, chloroprene rubber, styrene-butadiene rubber(SBR) to be put into mill and fully plasticated, front roll temperature≤40 ℃, rear roll temperature≤55 ℃, roll spacing 0.1～0.5mm, time 10～15min;
Add antioxidant D (N-phenyl-2-naphthylamine), antioxidant 4010 (N cyclohexyl N' phenyl P phenylene diamine), stearic acid, magnesium oxide, roller temperature is constant, roll spacing 0.5～1.0mm, time 2～3min;
Add zinc oxide, high abrasion carbon black, roller temperature is constant, roll spacing 0.5～1.0mm, time 5～6min;
Add altax (2,2'-dithio-bis-benzothiazole), captax (2-thiol group phenylpropyl alcohol thiazole), roller temperature is constant, roll spacing 0.5～1.0mm, time 2～3min;
Add Sulfur, roller temperature is constant, roll spacing 0.5～0.1mm, time 2～3min;
(eight is a kind of working method adopting in rubber compounding process cutter to eight cuttves, its objective is and promotes that rubber fully mixes with various Synergist S-421 95s, forms uniform mixed phase.Detailed process be with tapping knife along the direction of roller axially parallel with 45 ° of rubber tapping, the glue of piling up on roller is broken into volume, left and right is once respectively a cutter, eight times altogether), roller temperature is constant, roll spacing 0.1～0.5mm, time 6～8min;
Play triangle bag, roller temperature is constant, roll spacing 0.1～0.3mm, time 6～8min;
Slice, the film that roller temperature is constant, thickness is 1.0～1.5mm, time 1～2min;
(3), use vulcanizing press or rubber injection machine to vulcanize: cure conditions: 150 ℃ of temperature, time 10min, pressure 10MPa.
The present invention one selects the rubber having from reinforcing property (crystallization), and such material, when running into External Force Acting, can produce stretch crystallization, and Intermolecular Forces increases, and is intermolecularly difficult for slippage, fracture; The 2nd, select the material that volume effect is large, the damping action of increase and sharp object, to complete the impedance of extraneous sharp object.
According to above-mentioned principle, the present invention has adopted chloroprene rubber glue, natural rubber, styrene-butadiene rubber(SBR) co-mixing system.Chloroprene rubber molecular structure is regular, contains chlorine atomic polarity group in molecular chain, has increased intermolecular reactive force, under external force, easily produces stretch crystallization, is intermolecularly difficult for slippage, while running into sharp object, is difficult for being pierced, bursting.But chloroprene rubber is at low temperatures, produce after stretching and be difficult to restore to the original state, flexible resistance, winter hardiness are poor.Natural rubber, except having strain crystallization performance, has excellent cold tolerance, flexible resistance simultaneously, can make up the poor problem of chloroprene rubber winter hardiness.On styrene-butadiene rubber(SBR), contain a large amount of phenyl ring, by the volume effect the forming sharp object that can contact with it to external world with viscous effect form effective retardation.
The present invention is reasonable in design, by chloroprene rubber+natural rubber+styrene-butadiene rubber(SBR) ternary, also use method of design, when running into sharp object, material for sole of shoe is difficult for occurring the phenomenon of molecular chain slippage, fracture, greatly improve the anti-puncture performance at the bottom of boots, there is lightweight, the slow feature of conducting heat simultaneously, by professional institution, evaluate, the material of same thickness, its anti-puncture performance reaches advanced international level.Material thickness is that 2mm can reach 760N, has solved that metal anti-puncture layer weight loading is large, flexible resistance is poor, the fast problem of conducting heat.
