Description
Technical field
The present invention relates to footwear, more particularly to a kind of anti-piercing safety shoes and its manufacturing method.
Background technology
Safety shoe refers generally to people and wears to protect foot and leg from being contemplated that wound in different operating occasion
Harmful footwear are widely used in building, industries like chemical engineering and machinery.
Existing safety shoe in the midsole of safety shoe generally by being lining into steel plate, so as to increase the anti-puncture of safety shoe
Energy.But during actual job, people can be walked, run and even jump, and vola is in constantly bending and returns at this time
Multiple process.It, can not be with so as to cause the bending change of sole since the addition of steel plate can cause the bending of sole to be restricted
The bending change in upper vola, therefore people easily feel fatigue when time for wearing safety shoe is longer, have much room for improvement.
Invention content
The object of the present invention is to provide a kind of anti-piercing safety shoes.Under the premise of anti-penetration performance is ensured, the anti-puncture
Safety shoe can increase the bending property of sole, so as to reduce feeling of fatigue when people wear safety shoe.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of anti-piercing safety shoes, including sole and vamp, the sole is included positioned at external outsole, internally positioned interior bottom
And the anti-puncture pad between outsole and interior bottom, the anti-pad that pierces through are prepared by component A and B component for primary raw material；

Method includes the following steps：
First aramid fiber is placed in sodium hydroxide solution and impregnated, be placed in acetone soln impregnate again, is dried for standby；After drying
Aramid fiber be placed in the alcoholic solution of phosphate coupling agent impregnate after take out, baking.
By using above-mentioned technical proposal, for phosphoric acid as polymerization inhibitor, foaming agent can improve the service life of polyurethane, increase
Strong heat-insulating property.Crosslinking agent can make polyurethane generate cross-meshed structure.Catalyst can shorten the reaction time, promote solid
Change, improve production efficiency.Foam stabilizer belongs to surfactant, can increase the intersolubility of each component, play emulsification foam material,
Stable foam and the effect for adjusting abscess.During formation of foam, the precipitation of insoluble polyureas can destroy the stabilization of foam, even bubble
Agent can then be played the role of making polyurea dispersions, increase the compatibility of polyureas and foam base plate.By the poly- of polyester polyol generation
The ester group of urethane for a long time in wet environment or impregnate in water easily hydrolysis, ester linkage breaking, polymer degradation, produce carboxylic
Acid groups, and the presence of carboxyl accelerates the hydrolysis of ester group.The addition of stabilizer can inhibit and delay the ester group of polyurethane
Hydrolysis.
The features such as aramid fiber has density small, and modulus is high, intensity is high, elongation is low.But aramid fiber surface is smooth,
Phenyl ring steric effect is big, and active group is few, poor with the adhesiveness of polyurethane.Aramid fiber is changed with phosphate coupling agent
Property processing, on the one hand, long chain alkane base in phosphate coupling agent has preferable physical entanglement to act on polyurethane molecular chain；Separately
On the one hand, the phenyl ring in phosphate coupling agent has preferable compatibility with aramid fiber, and the two interaction influences each other, from
And improve the interface adhesion of polyurethane and aramid fiber, the intensity of polyurethane can be finally promoted, there is good anti-puncture
Performance.Compared to the mode that steel plate is lining into the midsole of safety shoe, the bending property of the safety shoe greatly enhances, so as to reduce
People wear feeling of fatigue during safety shoe.
The present invention is further arranged to：A concentration of 0.5wt% of the sodium hydroxide solution, the aramid fiber is in hydrogen-oxygen
It is 1h to change soaking time in sodium solution, and soaking time is 12h in acetone soln, and alcoholic solution solute is ethyl alcohol, and pH 5 is baked
Temperature is 80 DEG C.
By using above-mentioned technical proposal, in acid condition, the isopropyl of phosphate coupling agent is easy to hydrolyze, generation
- POOH have high activity, can react in a heated condition with the-NH2 of aramid fiber surface, so as to by phosphate idol
Connection agent is grafted to aramid fiber surface.
The present invention is further arranged to：The foaming agent is pentamethylene, pentane, isopentane or normal butane.
By using above-mentioned technical proposal, pentamethylene, pentane, isopentane or normal butane belong to alkanes foaming agent,
With liquid low boiling point attribute, gasified by absorbing the heat of chemical reaction generation, make polyurethane foam.In hard bubble production
Material mixing initial stage, generate a large amount of heat within tens of seconds, foaming agent absorbs partial heat, while the gasification of foaming agent makes
Foam Expansion foams.The thermal conductivity of foaming agent is low, assigns high rate of closed hole hard polyurethane foam excellent heat-proof quality.
The present invention is further arranged to：The crosslinking agent is ethanol amine, diethanol amine or triethanolamine.
By using above-mentioned technical proposal, ethanol amine, diethanol amine and triethanolamine are to contain hydroxyl and amido simultaneously
Compound.Ethanol amine, diethanol amine and triethanolamine are the thick liquid of water white transparency, can increase alkalinity.
The present invention is further arranged to：The catalyst be N, N- dimethyl cyclohexyl amines, triethylamine or triethylenediamine.
By using above-mentioned technical proposal, N, N- dimethyl cyclohexyl amines, triethylamine and triethylenediamine are urged for tertiary amines
The characteristics of agent has low volatility, and smell is small.
The present invention is further arranged to：The foam stabilizer is dimethyl silicone polymer or Siloxane-Oxyalkylene Copolymers.
By using above-mentioned technical proposal, dimethyl silicone polymer is colourless or light yellow liquid, tasteless, and transparency is high,
With heat resistance, cold resistance.Siloxane-Oxyalkylene Copolymers have good lubricity, and lower surface tension is preferably soft
Property and antistatic property, good levelability.
