In a preferred embodiment of the present invention, the motif material of described antiskid particles is at least a in chlorinated scoline, chlorinated butyl reclaimed rubber and chlorinated butyl reclaimed rubber/laminated nm-silicate composite material.
In a preferred embodiment of the present invention, the formula of described antiskid particles is: 100 parts of motif materials, 75 parts of reinforcing fillers, 0.5 part, antioxidant, 1.5 parts of ultraviolet (UV) resistant agent, 5 parts of colorants, 2.8 parts of vulcanizing agents, 2.5 parts of vulcanization accelerators, 15 parts of other compounding ingredients.
In a preferred embodiment of the present invention, the conditions of vulcanization of described antiskid particles is 170 ℃ * 8min.
The invention has the beneficial effects as follows: the preparation method of a kind of environment-friendly type nano PU of the present invention plastic cement race track, the preparation method is simple, between surface layer and basal layer without using pitch, it is moderate that prepared plastic cement race track not only has elasticity, outward appearance is beautiful, not shedding, easy care, the characteristics such as wear-resisting and attractive in appearance, and have economy and environmental protection applicability.
The specific embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
The embodiment of the present invention comprises:
A kind of preparation method of environment-friendly type nano PU plastic cement race track, preparation technology comprises: the preparation of surface layer and the preparation of basal layer;
Described surface layer is comprised of skid-proof rubber granulosa, RCPU glue-line and Combined-type plastic blob of viscose layer three part.The skid-proof rubber granulosa is mainly used in increasing the runway skin resistance, prevents sportsman's tumble injury of slipping when running fast, and the effect of RCPU glue-line is anti-skidding micelle, the gap, sealed lower portion Combined-type plastic blob of viscose joint on bonding top; The Combined-type plastic blob of viscose has good elasticity, not only does basis but also make surface layer.The Combined-type plastic blob of viscose forms with large-tonnage vulcanizing press molded vulcanization, and the limit section structure that cooperatively interacts, constitute an integral body mutually.
The laying process flow process of described surface layer is: Combined-type plastic blob of viscose-check planeness-establish mould-preparation RCPU glue-line-prepare antiskid particles layer-maintenance to place is checked-is prepared on basis.Wherein, the technological process of production of described combination plastic cement piece is: batching-kneading-stirring-lower layered material enters mould-paving sheet rubber-upper layer material and enters mould-matched moulds sulfuration.Described batching is: 100 parts of in-situ modified modified waste rubber powder compound material, 6～14 parts of NCO polyethers, 30～40 parts of other compounding ingredients.Described conditions of vulcanization is 160 ℃, 8MPa, 7min.
The thickness of described RCPU glue-line is 4～5mm.
Preparation technology's flow process of described antiskid particles is: motif material-formula-mixing-sulfidization molding-pulverizing processing-finished product.The motif material of antiskid particles adopts chlorinated butyl reclaimed rubber/laminated nm-silicate composite material, the formula of antiskid particles is: 100 parts of chlorinated butyl reclaimed rubber/laminated nm-silicate composite materials, 75 parts of reinforcing fillers, 0.5 part, antioxidant, 1.5 parts of ultraviolet (UV) resistant agent, 5 parts of colorants, 2.8 parts of vulcanizing agents, 2.5 parts of vulcanization accelerators, 15 parts of other compounding ingredients; The conditions of vulcanization of described antiskid particles is 170 ℃ * 8min.
Because the Combined-type plastic blob of viscose is abundant, length and width equal one or two runway width, and area is larger, adopt large-tonnage vulcanizing press molded vulcanization to form, so it does not need with basis bonding just very firm.For newly-built runway, due to surface layer without bonding with basis, therefore can be without bitumen layer, as long as compacting soil layer, hardcore bed, hard sand-lime surface layer three parts are arranged.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
