Description

Elephant-shaped recycled EVA landscape buoy

Technical Field

The utility model relates to a view buoy, in particular to regeneration EVA matter view buoy of pictographic mandarin duck 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 landscape buoy of pictographic mandarin duck.

The utility model adopts the technical proposal that: the utility model provides a regeneration EVA matter view buoy of elephant shape mandarin duck, by the mandarin duck body, fall the piece chamber, it constitutes to tie the ear and fall the piece, the mandarin duck body is below the centre has open cavity body structure, fall the cavity body structure of piece chamber for holding and including chamber wall and system hole, the chamber wall is square wall structure and go up open lower side of connection below the mandarin duck body, the system hole is the logical thru hole of rectangular shape and comprises four of distributing at chamber wall both sides lower extreme at least, tie the flat ear structure of rope ear for having connecting hole connection location tether and go up the front end of connection below the mandarin duck body, fall the piece for the square body that high proportion weighs down the soaking and install at the piece intracavity through the system hole by arranging the round pin, fall the body of piece chamber and tie the ear and be the water-fast EVA material of rope by regeneration and once inject the shaping as an organic whole structure according to the mould.

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 elephant-shaped landscape buoy is mainly used on landscape water surfaces, can meet the requirements of low cost, elephant-shaped color and four-season long-term storage by adopting regenerated EVA (ethylene vinyl acetate copolymer) materials, and can be positioned relatively without interference; through the design of the pendant block and the tether ears, the pendant block can effectively ensure that the pendant block normally floats without side turning and can move in a proper range so as to achieve the best simulation effect.

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, 1, a mandarin duck body, 2, a falling block cavity, 3, a rope tying ear, 4, a falling block, 5, a cavity wall, 6, a tying hole, 7 and a connecting hole.

Detailed Description

In the embodiment of fig. 1 and 2, a pictographic mandarin duck regeneration EVA landscape buoy comprises a mandarin duck body 1 and a falling block cavity 2, rope tying ear 3 and fall block 4 and constitute, mandarin duck body 1 has open cavity body structure for the centre below, fall the cavity body structure of block chamber 2 for holding and including chamber wall 5 and lacing hole 6, chamber wall 5 is square wall structure and go up the connection and open below mandarin duck body 1, lacing hole 6 is rectangular shape lead to the thru hole and comprises four of distributing at the 5 both sides lower extremes of chamber wall at least, tether ear 3 is for having connecting hole 7 to connect the flat ear structure of location tether and go up the front end of connection below mandarin duck body 1, fall block 4 for the waterproof square body that soaks of high proportion and install in falling block chamber 2 through lacing hole 6 by the round pin of arranging, fall block chamber 2 and tether ear 3 and follow the mould one shot forming structure as an organic whole by regenerated EVA material.

Example 1: 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.

Example 2: the utility model discloses a regenerated EVA material is for including mixture 98.6%, active oil 1.1%, promoter TMTD 0.3%'s material structure according to weight percentage, and this material is refined after the closed micelle that smelts into of mill through the closed mill, refines after the mill mixes the micelle into 1 millimeter and following film thickness with the micelle again, and the back roller diameter of the purpose-made mill of refining usefulness is 610mm, and preceding roller diameter is 480mm, and the back roller is 1 with the rotational speed ratio of preceding roller: 1.82, the rotation speed of a front roller is 50 revolutions per minute, the refining temperature is 148-152 ℃, sheets are produced at the thickness of 30 silk meters or less, and then the injectable granules are prepared by a granulator.

Example 3: firstly, erecting a pre-designed and prepared mould on an injection molding machine, then preparing regenerated EVA granules according to the physical property index requirement of a water surface buoy, injecting the regenerated EVA granules into the injection molding machine, and finally performing regenerated EVA injection molding on the pictographic mandarin duck landscape buoy.
