Description
Technical Field
The utility model relates to a solid tyre, in particular to regeneration EVA matter that contains interior child rides a car solid tyre belongs to rubber and plastic engineering technical field.
Background
Ethylene-vinyl acetate copolymer, EVA for short, because of introducing vinyl acetate monomer in the molecular chain, thus has reduced the high degree of crystallinity, has improved toughness, impact resistance, filler intermiscibility and heat sealability, is used in fields such as foamed shoe material, functional shed membrane, packaging mould, hot melt adhesive, wire and cable, car sealing element, daily plastic products and toys, etc. The shoe material is the most main application field of the EVA resin in China. Because the EVA resin blended foaming product has the performances of softness, good elasticity, chemical corrosion resistance and the like, the EVA resin blended foaming product is widely applied to soles and interior materials of medium and high-grade travel shoes, climbing shoes, slippers and sandals. In addition, the material is also used in the fields of sound insulation boards, gymnastic mats and sealing materials, and the EVA resin is widely applied in the fields of printing ink, cases, wine bottle mat covers and the like. Ethylene-vinyl acetate copolymer, one of the members of the major family of plastics, inevitably produces waste in the mass production and practical processes after being widely used, and how to recycle the waste and use the same grade as the virgin resin in the field of plastic products is a social environmental problem and also a major subject of the plastic recycling industry.
Disclosure of Invention
In order to solve the technical problem that the EVA regeneration link can make further extensive and furthest substitute the virgin resin of product, the utility model discloses a regeneration EVA quality that contains interior child rides a car solid tyre.
The utility model adopts the technical proposal that: the utility model provides a regeneration EVA matter solid tyre of driving on horse that contains interior child, by the solid inner tube of a tyre, cover tire and engaging lug constitute, the solid inner tube of a tyre is strip-shaped solid construction, the cover tire is the circle column structure of C style of calligraphy and including connecting face and antiskid face, it connects the lateral surface at the solid inner tube of a tyre to connect the face in the inboard face, antiskid face is at the lateral surface and for the concave convex surface that the recess that intersects that constitutes by boss and boss interval distribution is constituteed, the engaging lug is for including the engaging lug body and connect the polygon circle column structure including the face and by controlling two, it is the structure of cambered surface shape and connect the left and right sides limit at the solid inner tube of a tyre inner circle to connect the face, the engaging lug body is for having interior circle plane and to connecting the structure that the face in order far to extend into the ear, the solid inner.
The regenerated EVA material is composed of a mixture composed of a primary EVA material and a foamed EVA waste material containing dead materials, active oil and a promoter TMTD, the composition of the mixture is a target structure according to the requirements of products on the component structure of the primary EVA material, the component with the highest content proportion in each effective component of the EVA waste material is used as a conversion base number, the calculation is carried out according to the corresponding component proportion in the target structure, and then the mixture of the primary EVA material and the waste material is obtained after the components with insufficient corresponding target structures of the waste material are supplemented and added.
The utility model has the advantages that: after the precise structure of qualitative and quantitative analysis of each effective component of the waste material is confirmed, the waste material is filled according to a target structure to be added into a regenerated mixture, and the mixture replaces the original raw material to be reproduced according to the physical standard of the original raw material; the bicycle comprises multiple purposes and specifications, the solid tire is made of foamed EVA, the tire repair maintenance can be omitted and the tire breakage worry in the riding process can be avoided on the premise of ensuring physical indexes such as wear resistance, elasticity, color and the like, and particularly, the good benefit of the windy shared bicycle is more prominent in recent years.
Drawings
The present invention will be further explained with reference to the accompanying drawings:
fig. 1 is a schematic side view of the present invention;
fig. 2 is a schematic cross-sectional structure of the present invention.
In the figure, the tyre comprises a solid inner tyre 1, a solid inner tyre 2, an outer tyre 3, connecting lugs 4, an anti-skidding surface 5, a boss 6, a groove 7 and an inner circle plane.
Detailed Description
In the embodiment of fig. 1 and 2, a solid tyre of a regenerative EVA riding bicycle comprising an inner tyre and an outer tyre is composed of a solid inner tube 1, cover tire 2 and engaging lug 3 constitute, solid inner tube of a tyre 1 is the banding solid construction of circle, cover tire 2 is the circle column structure of C style of calligraphy and including connecting face and antiskid face 4, connect the face in the medial surface and connect the lateral surface at solid inner tube of a tyre 1, antiskid face 4 is at the lateral surface and for the concave-convex face that the recess 6 that intersects that constitutes by boss and boss interval distribution, engaging lug 3 is including the engaging lug body and the polygon circle column structure including connecting the face and by controlling two and constituteing, connect the face for the structure of cambered surface and connect the left and right sides limit at solid inner tube of a tyre 1 inner circle, the engaging lug body is for having interior circle plane 7 and to connecting the structure of the face in order far extending earning, solid inner tube of a tyre 1, cover tire 2 and engaging lug 3 are based on mould once injection moulding structure by the.
