Abstract
The invention provides a foam composite pad base material, which is characterized by comprising an opening foaming layer and a closed foaming layer stacked together; the opening foaming layer is a layer or multiple stacked layers, and the closed foaming layer is a layer or multiple laminated layers. The layers are firmly bonded together through an adhesive or thermal compounding. The base material provided by the invention has the energy absorption, flexibility and slow resilience of the opening foaming layer and the stability and support property of the closed foaming, is alternate hardness with softness, and comfortable and practical, and can be used as a base material for sport cushion, mattress and various leisure pads.
Description
Technical field
The present invention relates to a kind of foaming composite pad base material, can be used as the basic material of the sports goods pads such as mat proper, wushu pad, also can be used as the basic material of mattress or various rest pads.
Background technology
Current many sports goods pads, household articles pad and outdoor leisure pad are all used foaming polymer material to make for base material.The performance of mat is closely related with the foam structure of base material, and closed cell foamed material rebound performance is better, while occur clashing into resilience fast, energy can be rebounded, there is good support performance simultaneously; And hole-opening foaming material while occur clashing into resilience slow, can absorb unnecessary energy to prevent bounce-back, but the support property of hole-opening foaming material is poor, when people contacts with it, easily form local serious depression, affect dexterity of action.Therefore, make mat have good energy absorption performance and support performance concurrently, meet the demand of special occasions to these two kinds of performances, tool is of great significance.
In addition, sports goods pad, mattress or various rest pad all select bipeltate or foamed plastic as base material, but single plastics or rubber expanded material are difficult to have concurrently good elasticity, flexibility and hardness.Single rubber expanded material lacks hardness, and support strength is inadequate, and when people contacts with it, the larger depression of local easily formation, affects flexibility during motion, easily make people's astasia.Single plastic foam material apparent hardness is too large and lack flexibility, and when people contacts with it, comfort level is poor.
Summary of the invention
The problem to be solved in the present invention be to provide a kind of have good energy absorption performance, surface spring back slowly, have strong support, inner elastomeric is good, temper toughness with gentleness, use comfortable composite pad base material.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of foaming composite pad base material, described composite pad base material is successively formed by stacking by hole-opening foaming layer and closed pore foaming layer.
Wherein, described hole-opening foaming layer can be the superimposed of one or more layers, and described closed pore foaming layer can be the superimposed of one or more layers.The foamed plastic layer that described hole-opening foaming layer is perforate or the foaming rubber layer of perforate.The foamed plastic layer that described closed pore foaming layer is closed pore or the foaming rubber layer of closed pore.
Further, described foamed plastic layer is usingd one or more in polyethylene, polypropylene, polyvinyl chloride, polyurethane and ethylene-vinyl acetate copolymer as expanded material.
Described foaming rubber layer is usingd one or more in ethylene propylene diene rubber, neoprene and nitrile rubber as expanded material.
Preferably, described composite pad base material is divided into five layers, and from top to bottom, ground floor is hole-opening foaming layer, and the second layer is closed pore foaming layer, and the 3rd layer is hole-opening foaming layer, and the 4th layer and layer 5 are closed pore foaming layer.Wherein, described hole-opening foaming layer is foamed plastic layer, and described closed pore foaming layer is foaming rubber layer.
Further, the perforate of described hole-opening foaming layer partly obtains by several apertures are set in closed pore foaming layer, as can be obtains closed cell foamed material by acupuncture means.Meanwhile, can be also directly to form in foaming process.
The density of described hole-opening foaming layer, closed pore foaming layer is 20～300kg/m
3.Described hole-opening foaming layer and hole-opening foaming layer, closed pore foaming layer and closed pore foaming layer, hole-opening foaming layer and closed pore foaming layer are all by together with adhesive or hot compound good bond.
Advantage and good effect that the present invention has are:
1. the energy absorption capacity of the existing absorbing energy layer of this composite pad base material and slow resilience, have again elasticity and the hardness of supporting layer, absorbing energy layer and supporting layer cross arrangement, and performance is supplemented mutually, meets Special use requirement.When people and mat occur to clash into, the hole-opening foaming layer on surface can cave in fast and absorb the excess energy of collision, slowly resilience; The closed pore foaming layer of bottom can be played good supporting role again, and the active force producing can be effectively distributed on whole mat, can not produce obvious part and seriously cave in.
2. the flexibility of the existing soft layer of this composite pad base material and elasticity, have again hardness and the supportive of enhancement layer, soft layer and enhancement layer cross arrangement, and performance is supplemented mutually, reaches and tempers toughness with gentleness.People on mat time, had both kept good contact flexibility, made again the active force of its generation can effectively be distributed on whole mat, can not produce obvious local dent; Existing good elasticity and recovery, have again good stability and supportive simultaneously.This is a kind of hard and soft suitable flexible composite pad base material that has concurrently again, is comfortable and practical good combination.
