Description
Technical field
The present invention relates to the material manufactured at the bottom of boots, be specially a kind of Puncture resistant boot sole material.
Background technology
Along with the development of guard technology; all kinds of footwear (boots) is of a great variety; various function is also day by day perfect; particularly some special occasions; as fire protection sector needs to have the functions such as fire-retardant, corrosion-resistant, anti-skidding, anti-puncture, protection to military toxic agent, high-risk chemical to be possessed for military Protective Boots (footwear), there is fire-retardant, anti-puncture ability simultaneously.No matter for military or civilian, anti-puncture performance at the bottom of boots 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), produces harm to human body.
Boots bottom material is when contacting sharp object, and the slippage of molecular chain, fracture very easily occur, and 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 while effectively improving anti-puncture performance, also bring the problem of three aspects: one is that weight metal is large, increases the physiological stress of human body; Two is that the flexibility at boots (footwear) end is poor; Three is that metal level easily transmits surface temperature, and in high temperature or microthermal climate, easily worsen boots (footwear) interior temperature and humidity, comfortableness is poor.
Summary of the invention
The present invention to add metal put puncture layer and the problems referred to above of existing to solve in boots bottom material, provides a kind of Puncture resistant boot sole material.
The present invention adopts following technical scheme to realize:
A kind of Puncture resistant boot sole material, is made up 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 Puncture resistant boot sole material is as follows:
(1) consumption of various rubber and Synergist S-421 95, is weighed by formula rate;
(2), mill is used to carry out mixing: natural rubber, chloroprene rubber, styrene-butadiene rubber(SBR) are put into mill and fully plasticated, front roll temperature≤40 DEG C, rear roll temperature≤55 DEG C, 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 be constant, roll spacing 0.5 ~ 1.0mm, time 2 ~ 3min;
Add zinc oxide, high abrasion carbon black, roller temperature be 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 be constant, roll spacing 0.5 ~ 0.1mm, time 2 ~ 3min;
(eight is a kind of working method adopted in rubber compounding process cutter, its objective is and promotes that rubber fully mixes with various Synergist S-421 95, form uniform mixed phase for eight cuttves.Detailed process uses tapping knife along roller shaft to parallel direction with 45 ° of rubber tapping, and the glue that roller is piled up is broken into volume, and 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, roller temperature is constant, thickness is the film of 1.0 ~ 1.5mm, time 1 ~ 2min;
(3), vulcanizing press or rubber injection machine is used to carry out sulfuration: cure conditions: temperature 150 DEG C, time 10min, pressure 10MPa.
The present invention one selects the rubber had from reinforcing property (crystallization), and such material, when running into External Force Acting, can produce stretch crystallization, and Intermolecular Forces increases, intermolecular not easily slippage, fracture; Two is the materials selecting volume effect large, increases the damping action with sharp object, to complete the impedance of extraneous sharp object.
According to above-mentioned principle, present invention employs chloroprene rubber glue, natural rubber, styrene-butadiene rubber(SBR) co-mixing system.Chloroprene rubber molecular structure is regular, containing chlorine atomic polarity group in molecular chain, adds intermolecular reactive force, under external force, easily produces stretch crystallization, intermolecular not easily slippage, when running into sharp object, be not easily pierced, bursting.But chloroprene rubber 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 problem of chloroprene rubber winter hardiness difference.Containing a large amount of phenyl ring on styrene-butadiene rubber(SBR), by the volume effect formed form effective retardation with the sharp object that viscous effect can contact with it to external world.
The present invention is reasonable in design, by chloroprene rubber+natural rubber+styrene-butadiene rubber(SBR) ternary also by method of design, when running into sharp object, not easily there is the phenomenon of molecular chain slippage, fracture in material for sole of shoe, greatly improve the anti-puncture performance at the bottom of boots, there is lightweight, slow feature of conducting heat simultaneously, evaluated by professional institution, the material of same thickness, its anti-puncture performance reaches advanced international level.Material thickness is that 2mm can reach 760N, solves that metal anti-puncture layer weight loading is large, flexible resistance is poor, fast problem of conducting heat.
