Description
Technical field
The present invention relates to the pedaline field, exactly refer to the gum of a kind of pedaline.
Background technology
Since artificial turf have anti-aging, sun-proof, waterproof, anti-skidding, wear-resisting, comfortable foot feeling, lovely luster, long service life, maintaining expense low, the advantage such as can round-the-clockly use, therefore, recently be widely applied in multiple occasions such as stadiums, school, hotel and building roofs.At present, the structure of existing artificial turf, it mainly is comprised of grass, the careless end and gum.Usually, grass and the grass end, made by thermoplastic macromolecule material, and for example grass is mainly made by polyethylene, and the grass end is mainly made by polypropylene, and gum then usually for example vulcanizes carboxylic styrene-butadiene rubber by thermoset cross-linked macromolecular material or urethane is made.The effect of gum is that grass is fixed on grass at the end, makes grass be difficult for extracting out from the grass end.Gum should be able to be bonded together polyethylene, polypropylene, also will have simultaneously certain intensity, the performance such as water-fast, heat-resisting, cold-resistant, anti-aging.For example, existing artificial turf gum is made by carboxylic styrene butadiene latex, calcium carbonate, sulphur, promotor usually, specifically at a certain temperature (as more than 145 ℃), cause the crosslinked of carboxylic styrene butadiene latex by vulcanization system (sulphur, promotor), obtain vulcanizing carboxylic styrene-butadiene rubber.Carboxylic styrene-butadiene rubber behind over cure is thermoset macromolecule material, and molecular chain is cross-linked structure, and is molten not insoluble, can only decompose after being heated, and can not soften, and can not be returned to plastic state.
In the existing artificial turf, grass and the grass end be by thermoplastic macromolecule material for example polyethylene, polypropylene make, and gum is to be made by sulfuration carboxylic styrene-butadiene rubber or this class thermoset macromolecule material of cross-linked polyurethane.As everyone knows, thermoplastic macromolecule material can repeatedly thermoplastic in specific temperature range, cooling curing machine-shaping.And thermoset cross-linked macromolecular material is behind sulfidization molding under the conditions such as certain temperature, just no longer can the again machine-shaping by the rising temperature.Thereby the consistency between the two is poor, can not be by the simultaneously recycling of the methods such as melt blending.So, can not unify recycling by the existing artificial turf of the materials such as polyethylene, polypropylene, carboxylic styrene-butadiene rubber or urethane preparation.On the one hand, discarded or burning can cause environmental pollution and the wasting of resources; On the other hand, again recovery being separated at grass and the grass end with gum can cause cost recovery too high.
At present, mainly there is following drawback in existing gum material:
1, not environmental protection:
A, have the volatilization of VOC to be unfavorable for environmental protection: the gum of conventional pedaline generally be carboxylic styrene butadiene latex or non-plasticizing type acetic acid second rare-ethylene copolymerization emulsions is as main raw.Can only reach nineties percent because the reactivity of monomer is the highest in the process of polymerization, so can contain in this case a certain amount of volatile organic matter (being VOC) in the latex, production link under connecing: joining in the process of glue stirring, gluing and gum baking all to have a large amount of obnoxious flavoures to discharge, health on the staff causes bad impact, also can become certain pollution to surrounding environment simultaneously.And the VOC in the gum can not evaporate quickly, also can damage the human consumer in ensuing finished product use procedure, also can pollute environment for use simultaneously.The existence meeting of B, heavy metal causes certain pollution to environment: generally add a certain amount of calcium class material in the latex fabrication of gum as filling in main material latex, general production saving cost of poor quality selects coarse whiting as packing material.Heavy metal content in the coarse whiting in this case is generally higher.So in the use procedure of reality, can cause certain injury to the human consumer especially health of the aspects such as growth of children colony in age.
2, weathering resistance is good not, especially aspect acid and alkali-resistance: add inorganic calcium powder and stir and form through baking process because the gum of traditional pedaline is latex, dry linting in various degree in general acid proof test, all can occur and have a certain amount of bubble to occur (being mainly the CO of calcium carbonate and acid-respons generation
2), so be immersed in for a long time the phenomenon that efflorescence appears in gum in the sour environment easily in the flourishing zone of industry.
3, reusable edible does not cause waste to the energy: owing to contain a large amount of inorganic fills in the traditional artificial grass stamp gum, and general adopt or black, this causes very large difficulty to recovery, in general plastic parts, be difficult to fill, the cost of modification generally can be very high, so general pedaline has been disposed as rubbish at the Shi Douhui that dies, this is again a greatly pollution concerning environment because the degradation cycle of plastics generally needs very for a long time, also is very large waste concerning the energy of day by day shortage simultaneously.

Embodiment
For those skilled in the art can understand technical scheme provided by the present invention better, set forth below in conjunction with specific embodiment.
The gum of pedaline provided by the invention comprises following component:
Above component is the component proportioning by weight, and take PE as 100 parts weight as benchmark; Carry out the blend batching with homogenizer after adding other subsidiary material, glue is melted in the shearing formation through screw rod under the high temperature of 140 ~ 220 degree of mixed material, buffering through the glue groove is carried out the distribution of horizontal 4 meters fabric widths to melting glue, then carry out the glue-spreading operation under the effect of Frictioning device and the flat effect of flow by gravity; Gum is through being to improve the appearance effect of careless line and the control of gum binding force in the process of baking oven, and when glue-spreading, the temperature of careless face one side is controlled at 50 ~ 80 degree, and the temperature of back-adhesive surface is controlled at 100～150 degree.
Wherein PE is the polyvinyl resin after the modification, and EVA is the material modified of ethylene-vinyl acetate.
100% PE also can be used as the operation that gum is finished gum in initial selection experiment, but the temperature of experiment can will exceed the 50-80 degree than the temperature after improving, higher temperature can impact the quality of grass silk, the film forming insufficient strength of gum is large simultaneously, and melten gel is mobile bad, causes the binding force of turf not reach desired value.Therefore consider in the process of modification that adding some suitable subsidiary material carries out modification to material.
EVA: the transparency that in the flowability that reduces melten gel, can improve gum.The melt temperature of EVA is lower, melting index larger (namely mobile relatively good) transparency is higher, the flowability of melting glue improves greatly with the change that EVA measures, but gum becomes film strength also to descend thereupon, becomes the net effect of film toughness to reach best situation with gum in resin and the flowability of gum when the ratio of EVA is 1:1; Otherwise extraordinarily become film strength improving but the flowability of gum is but descending with the reduction of EVA ratio, the reduction of melting the glue flowability directly affects the quality of gum, and flowability and the gum intensity of melting glue when the adding proportion of EVA is 10 parts form another point of crossing.
Although rosin has certain impact to the transparent color and luster of gum to a certain extent, but it has good help aspect sticking power of gum, can improve the bonding of gum and base material, simultaneously the binding force of turf had certain help, the binding force that adds suitable rosin turf under equal conditions can improve 10%-20%.The adding of rosin can effectively reduce the cost of gum, but go and affect gum color and the surface smooth degree.0.1-15 part scope in can under the prerequisite of the color that guarantees to melt glue and surperficial smooth degree, effectively guarantee the binding force of turf gum.
The adding of paraffin mainly is to improve the flowability of gum when molten state, is conducive to the gap between melten gel filling grass silk and the bottom in the process of turf gum, can improve the stability of grass silk on the bottom.The adding of paraffin can effectively improve the flowability of gum, but along with the increasing transparency extraordinarily of paraffin ratio descends, the simultaneously rapid decline of wear-resistant effect of gum, the net effect in 5 ~ 10 parts scope is worth adopting.
The adding of fiber mainly is intensity and the toughness that improves gum.But melt the flowability of glue along with the adding of fiber in rapid decline, so generally the addition of fiber is lower, general control is in 0.1 ~ 1.0 scope.
The adding of antioxidant mainly is the resistance of oxidation that improves gum, improves its weathering resistance.Reacting of the oxide compound in prevention molecular chain and the external world, adding proportion is too low for affecting the antioxygen of gum, causes waste can affect cost simultaneously otherwise add to take too much.According to the market of different trade mark oxidation inhibitor on the market, adding proportion generally is 0.1 ~ 0.5 part.
The adding of anti UV agent mainly is the ultraviolet line ability that improves gum, improves its weathering resistance.Stop molecular chain to change under ultraviolet effect and cause decomposition reaction, adding proportion is too low for affecting the anti-UV effect of gum, causes waste can affect cost simultaneously otherwise add too many expense.According to the market of the anti-UV agent of the different trades mark on the market, adding proportion generally is 0.1 ~ 0.5 part.
