The foam cushion is capable of providing elastic buffering for activity cushions such as artificial turf poor in foot feel and is free of corrugation caused by thermal expansion, great in smoothness and wide in adaptable temperature difference range, and comfort and firmness of the artificial turf and the like are greatly improved.

Description

A kind of foam pad
Technical field
The invention belongs to foam technology field, it is related to a kind of foam pad.
Background technology
In recent years, with the industrialization of the motions such as football, tennis, golf, commercialized development, the development of chinampa Also very fast.Chinampa can be applied not only to sports field, applies also for various leisure, furnishing fields.
The chinampa that existing sports ground uses typically is made up of with the artificial grass filaments being fixed on base fabric base fabric, existing In technology, the base fabric of chinampa is typically made up of one layer of composite, and in use, feel is really up to the mark on this lawn, foot Sense is poor, and shock-absorbing capacity is also undesirable, especially when carrying out the strenuous exercises such as football or tennis on chinampa, is also easy to be subject to Wound.At present, have and add cushion in chinampa underlay, for example, the Chinese patent of Patent No. 201120188248.7 is also public Open a kind of high-elasticity artificial turf, elastomeric layer has been set, existing chinampa and highly elastic material bonding have been formed overall Structure.So preferable protective effect can not only be played to the human body in motion, protect human motion joint, reduce motion and damage Wound and exercise fatigue, increased the comfortableness performing physical exercises on chinampa, also improve making of chinampa simultaneously Use the life-span.But in use, due to the change of the temperature difference, lead to expanding with heat and contract with cold of material, elastomeric material and chinampa Thermal expansion and contraction degree inconsistent, cause lawn wrinkling, uneven, impact feel and lawn normal use.
Content of the invention
It is an object of the invention to provide a kind of foam pad, when can be used for the such as artificial space for activities such as chinampa, pad, use Feel is good, elastic good afterwards, and when using, even if having expanding with heat and contract with cold, is also not in wrinkling phenomenon.
The above-mentioned technical purpose of the present invention has the technical scheme that a kind of foam pad, including foam Material layer, described sponge layer includes the first sponge layer and the second sponge layer and is arranged on described first foam Limiting layer between material layer and the second sponge layer, the thermal coefficient of expansion of described limiting layer is less than described first foamed materialss Layer and the thermal coefficient of expansion of described second sponge layer.
Foam provide elastomeric simultaneously as the retractility ratio of foam is larger, can expand with heat and contract with cold, especially in high temperature Under, expand substantially, can be to it using bringing defect, technique scheme, by the middle of first, second two layers of foam material layer The limiting layer that setting can be stretched with limit foam material layer, under low temperature, hot conditionss, the retractility very little of limiting layer itself, The telescopicing performance of sponge layer can effectively be controlled so that the retractility on whole foam pad horizontal direction is good, will not go out Existing fold, flatness is good, and range of application is wider, can be widely used for the place having telescopicing performance requirement to froth bed.
Restriction effect preferably, described limiting layer has network structure, to first, second sponge layer retractility More preferably.
Preferably, having the network structure of longitude and latitude line formation in described limiting layer.
Preferably, the thermal coefficient of expansion of described limiting layer is at least below described first sponge layer and the second foam material The 1/10 of relatively low thermel expansion coefficient in the bed of material.
Preferably, there is thickness difference between described first sponge layer and described second sponge layer.
Preferably, the raw material of described limiting layer is glass fibre or non-woven fibre or ceramic fibre or bamboo fibre One or more of.
Preferably, the raw material of described sponge layer be polyvinyl chloride foam material, polyethylene foam material, chemistry hand over Connection polyethylene foam-material, IXPE expanded material, modified poly ethylene expanded material, modified polypropene foaming material One or more of material, polystyrol foam material, polyurethane foam material, modified polyurethane expanded material.
Above-mentioned selected several elastic foam material layer raw material, the elasticity of itself is good, can meet chinampa feel and relax Suitable needs, had both had certain elasticity, and coefficient of thermal expansion and contraction is rationally, and retractility is again more stable, with joining of limiting layer Right higher.
Preferably, the raw material of described sponge layer be processes for chemically crosslinked polyethylene expanded material, polyethylene foam material, One or more of modified poly ethylene expanded material, polyurethane foam material, modified polyurethane expanded material.
Preferably, described modified poly ethylene expanded material is modified rubber polyethylene foam-material.
Preferably, modified rubber polyethylene foam-material is prepared as follows:
(1) dispensing: by weight, polyethylene 70-80 part, butadiene rubber 20-35 part, cumyl peroxide 1-3 part, oxidation Zinc 1-3 part, stearic acid 0.5-1 part, sulfur 1-2 part, citric acid 0.1-0.3 part；
(2) just mix: polyethylene, cumyl peroxide, zinc oxide, sulfur mixing obtain primary reaction thing；
(3) two mix: described primary reaction thing, butadiene rubber, stearic acid mixing obtain and secondary reactants；
(4) mixed eventually: citric acid to be added in described secondary reactants, under the conditions of temperature is for 75-80 DEG C, insulation 1-1.5 is little When, then carry out refining material: temperature is risen to 105-110 DEG C and maintains 10-15min, temperature to be down to 75-80 DEG C of maintenance 30-35min, Obtain modified rubber polyethylene foam-material.
In such scheme, by rubber, polyethylene is modified, improves the elastic stability of resilient foam layer and stretch Stability, adds zinc oxide, sulfur and citric acid, can improve modified effect so as to while ensureing snubber elastomeric, flatulence of heat type Contraction coefficients decrease, higher with the fitness of limiting layer, are also not in that lawn is wrinkling not in the case that the temperature difference is larger Flat phenomenon.
Preferably, setting between described limiting layer and described first sponge layer and/or described second sponge layer It is equipped with articulamentum, strengthen attachment force between each layer it is ensured that the firmness on lawn.
Preferably, by weight, described articulamentum includes polyurethane 25-30 part, the many isocyanides of polymethylene polyphenyl Acid esters 20-25 part, vinyl synthetic resin emulsion 25-35 part, solvent 3-5 part, accelerator 1-3 part, filler 6-8 part, stabilizer 1-3 part.
Above-mentioned articulamentum can meet bonding between the material of multiple different heat expansion coefficients, and cohesive force is strong.
By implementing technique scheme, the foam pad that the present invention provides, can be the activity of the feels such as chinampa difference Pad provides elastic buffer, and will not be wrinkling because of thermal expansion, and planarization is good, and adaptable temperature range is big, significantly carries The comfort level of high chinampa etc. and firmness.
