Description
Technical field
The present invention relates to ice skates production technical fields, and in particular to a kind of to reduce the ice skates ice destroyed to ice face
Knife and its production technology.
Background technology
The skates of ice skates are broadly divided into three classes according to structure and movement characteristic：Speed skate blade, figure skate, ice hockey ice
Knife.Although three kinds of skates have difference, it is substantially similar that ice field reason is pedaled when sliding.Existing skates blade is very thin, even
Its Maximum Contact area with ice face of the longest speed skate of blade is also less than 10 square centimeters, therefore while skating generates in ice face
Very big pressure makes the fusing point of ice reduce very much, and the ice of skates contact is fused into water, and the frictional force between skates and ice is made to drop more
It is low, it is more advantageous to the sliding of skating boots.But this mode can cause ice face to be easy to melt and will produce a large amount of ice slag, ice very much
Slag extruding may result in ice face out-of-flatness, needs the cleaning of timing, and the thickness of ice reduces, is sprinkled behind closing place that be often
Water supplements the thickness of ice, can increase the cost of operation in this way, reduces the benefit of operation.And ice skates currently on the market
Damping effect is poor, main reason is that the structure of the damping of existing ice skates is all provided in the connection of skates and shoe body
Place, usually the material of rubber, shock-damping structure unanimously carry all wt and impact force of human body, the structure actual change of damping
Amount meeting very little, therefore the damping also just played the role of is also little, damping is harder, and special point ice is especially done in skater
When the action of rotation, the damping played obtains that effect is less obvious, and the damage of bigger can be caused to ice face.
Invention content
Technical problem to be solved by the present invention lies in a kind of good damping effect is provided, intensity is high, and it is less to generate ice slag
The ice skates skates destroyed to ice face and its production technology can be reduced.
The technical problems to be solved by the invention are realized using following technical scheme：
It is a kind of to reduce the ice skates skates destroyed to ice face, it is characterised in that：It is described including skates plate and skate blade
Skate blade be fixed at the downside of skates plate, be both configured to arc-shaped on the downside of the section of the skates plate and skate blade,
The skate blade is elastic polyurethane material.
A kind of production technology that can reduce the ice skates skates destroyed to ice face, it is characterised in that：By the following method
It carries out
Skates plate and skate blade are produced, then fixes the two,
Elastic polyurethane is that base polyurethane prepolymer for use as, polymer, lubricant and curing agent mixing are poured into a mould after de-bubble and cured
It arrives；
The base polyurethane prepolymer for use as is that react 2-3 at 70-90 DEG C by polyether polyol and isocyanate compound small
When and obtain, the mass ratio of the polyether polyol and the isocyanate compound is 1: 2-3；Point of the base polyurethane prepolymer for use as

The curing agent includes 0.2~0.4 part of catalyst and 4-6 parts of crosslinking agent by weight.
The skates plate and skate blade are riveting or by together with being fixedly installed by way of cohering.
The front-end and back-end of the skates plate and skate blade are both configured to spherical surface.
The elastane of the raw material production department of elastane of the present invention, have good working performance,
Hardening capacity and excellent endurance quality, and elasticity is good, and lubricity is good.
The catalyst of the present invention can promote the raw material of the polymer of the present invention that polymerisation quickly occurs, and can
Play the role of promoting in the curing schedule of elastic polyurethane synthesis cured.The present invention not will produce substantially when solidification
Foam is conducive to the uniformity of elastic polyurethane, improves the quality of product.
The present invention is added under conditions of tetrafluoraoethylene-hexafluoropropylene copolymer is with γ-trifluoro propyl methyl polysiloxane
The lubrication of polyimides and polysiloxanes is it is anticipated that not only acted as the effect of two kinds of raw materials of connection, to reducing tetrafluoro second
Alkene-hexafluoropropylene copolymer directly vulcanizes the difficulty of combination simultaneously with γ-trifluoro propyl methyl polysiloxane, and plays more preferable
Lubricant effect.
The present invention is elastomer combined material, and cost of manufacture is relatively low, and environmental protection, the product expected using the combination is being ensured
With excellent mechanical property while transparent.Two-component system is used simultaneously, makes product processing can be in lower temperature
Lower progress, and demoulding time can be shortened, improve production efficiency.
The beneficial effects of the invention are as follows：The present invention is good damping effect, and intensity is high, generates that ice slag is less can be reduced pair
Ice face is destroyed.
