Description

Regenerated EVA (ethylene-vinyl acetate) floor clock base with support frame

Technical Field

The utility model relates to a clock panel, in particular to regeneration EVA matter that has support frame falls to ground clock seat 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 regenerated EVA quality floor clock base with a support frame.

The utility model adopts the technical proposal that: a regenerated EVA floor clock base with supporting frame is composed of a clock base body with cylindrical surface and grains, a circular plate structure, a front surface with radial time markers and central pinhole, and a mounting chamber consisting of a cavity for installing clock parts and a recess on its back surface and communicated with said circular plate structure The floor base and the supporting frame are formed into an integral structure by one-time injection molding of regenerated EVA materials according to a mold.

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 production of floor clock base by regenerated EVA material is a boldly attempt of regenerated plastic products, and the products completely meet the environmental protection requirements of European Union and obtain the passing permission after being detected by European customs, thereby effectively reducing the production cost of floor clock base and opening up the product channel of regenerated EVA material.

Drawings

The present invention will be further explained with reference to the accompanying drawings:

fig. 1 is a schematic front structural view of the present invention;

FIG. 2 is a schematic side sectional view of the present invention;

fig. 3 is a schematic view of the front cross-section structure of the present invention.

In the figure, the clock base body 1, the clock base 2, the floor base 3, the support frame 4, the panel 5, the installation chamber 6, the time symbol mark 7 and the clock hand shaft hole are shown.

Detailed Description

In the embodiment of fig. 1, 2, 3, a regenerative EVA floor clock base with a support frame is composed of a clock base body 1, a floor base 2 and a support frame 3, the clock base body 1 is a cylinder structure with decorative texture on the periphery and comprises a panel 4 and an installation chamber 5, the panel 4 is a circular plate structure and the back surface is connected with the front surface of the clock base body 1, the front surface of the panel 4 is distributed with radial time symbols 6 and the center is provided with a clock needle shaft hole 7, the installation chamber 5 is an installation chamber of a clock machine member and is composed of a concave cavity on the back surface of the clock base body 1, the clock needle shaft hole 7 is communicated with the installation chamber 5, the floor base 2 is a cone structure with decorative texture and the upper surface is connected with the lower side of the clock base body 1, the support frame 3 is composed of a support ring and a support bar made of hard strip material including metal strips, the support ring is connected in the clock base body 1, the support bar is composed of two support bars and the, the support bars are connected to two sides in the floor base 2, and the clock base body 1, the floor base 2 and the support frame 3 are formed into an integral structure by one-time injection molding of regenerated EVA materials according to a mold.

The EVA material regenerated in example 1 is a mixture of raw EVA material and foamed EVA waste material containing dead material, active oil and promoter TMTD, the composition of the mixture is a target structure according to the requirements of the product on the component structure of the raw EVA material, the component with the highest content proportion in the effective components of the EVA waste material is used as a conversion base number, the corresponding component proportion in the target structure is calculated, and then the mixture of the raw material and the waste material is obtained after the shortage of the component with the corresponding target structure of the waste material is supplemented.
