Abstract

The present invention relates to a foamed float on a fish wire and its preparation method. Said foamed float includes a foamed plastic body which has a threading eye and can be slip-positioned on the fish wire, the external surface of the plastic body and internal wall of the threading eye posses non-foamed hard-shell layer respectively, the interior of the plastic body is of cellular foamed body, and the thickness of said hard-shell layer is 0.5%-5% of the diameter of said plastic body, and between the hard-shell layer and foamed body there is a transition layer from fine foaming progressively to loosely-foaming so as to have no clear interface between them. Its prepn. method includes the following steps: using foaming polystyrene whose foaming rate is 40-60 times and commercial model number is EPS202 or EPS303 as raw material, heating and pressing in mould, and foaming-forming in the mould so as to obtain the invented product with high surface hardness, smooth finish, and integrated

Description

Foamed float for angling and preparation method thereof

What the present invention relates to use on a kind of fishing tackle is cursory, and particularly a kind of appearance has foamed float for angling of crust layer and preparation method thereof.

In the prior art, the cursory float that can replace original traditional fishing tackle that has a kind of foamed plastic to form, buoyancy greatly strengthens; Through wires hole is arranged and make its location of on fishline, sliding, help regulating the position of fish hook in water, easy to use.But the foamed plastic on the market is cursory is a kind of plastic body of integral foam, and its appearance does not have crust layer, and the appearance pressurized promptly is absorbed in into pit; Intensity is low, and is easily cracked; The surface is more coarse, and also not shinny after the japanning, reflectance is lower, influences serviceability.Its preparation method is to adopt large size plastic jetting-moulding device to carry out injection moulding and foaming, and its equipment investment expense is big, only is fit to large-scale production in enormous quantities.

The object of the present invention is to provide a kind of serviceability better, the foamed float for angling that service life is long and the few preparation method of equipment investment of suitable small-scale production thereof.

For achieving the above object, the present invention adopts following technical proposals: foamed float for angling of the present invention is the same with prior art to include the slide foamed plastic type body that through wires hole is arranged of location of an energy on fishline.It is characterized in that external table of type and through wires hole inwall have the not crust layer of foaming, and the inside of type body is cellular foaming body; Crust layer thickness is 0.5%～5% of type body diameter; Have between crust layer and the foaming body by trickle foaming gradually to the loose transitional horizon that foams, make no obvious interface between crust layer and the foaming body, the hardness of its crust layer and intensity are identical with the hardness and the intensity of foamed plastic not, thereby improved intensity, appearance hardness and the fineness of type body, improved serviceability and increased the service life.Type body material can adopt styrofoam.

The foamed float for angling that above-mentioned appearance is had crust layer, the present invention adopts following preparation method: with expansion ratio be 40～60 times, commercially available model is that the expandable polystyrene of EPS202 or EPS303 is a raw material, adopt the pressurized, heated mould and prepare moulding in the foam-in-mould method of forming.Its step of preparation process is: 1. with one pair of two involutory Die and mould plate separately and die cavity upwards keeps flat, wherein put in the die cavity of a Die and mould plate and draw together behind the dried raw material flatly with plate, put into drawing together with plate behind the water-moistened wet feed material flat in the die cavity of another piece Die and mould plate; 2. will adorn that the Die and mould plate of wet feed material is topped to be integral with clamp being equipped with on the Die and mould plate of dried raw material, and put on stainless pin at the die cavity through wires hole of Die and mould plate; 3. whole pair of mould placed and be heated to 120 ℃～150 ℃ in the pressure vessel, pressure is 0.1～0.6Mpa, is incubated 2-5 minute; 4. take out and promptly go out product after mould is cooled to room temperature rapidly with running water.The method of mold heated can be: heating wire heating or FAR INFRARED HEATING or electric heating installation using oil as medium heating or high-frequency heating or Steam Heating.

The present invention has following conspicuous outstanding feature and remarkable advantage compared with prior art: the appearance of foamed float for angling of the present invention has the not crust layer of foaming, thereby surface hardness is higher, and pressurized is difficult for presenting pit; Bulk strength is higher, and is not easily broken, and service life is longer; Surface smoothness is higher, the reflectance height, and the X serviceability is better.The present invention adopts two Die and mould plates to synthetic one pair of mould, is integral by clamp, pressurize then and heat to be incubated with timing, and cooling rapidly subsequently, its equipment investment is very little, is suitable for small-scale production.

The drawing of accompanying drawing is described as follows:

A most preferred embodiment of product of the present invention is: referring to Fig. 1, this foamed float for angling includes the foamed plastic type body 1 that through wires hole is arranged that an energy slides and locatees on fishline, type body 1 is a spherical, type body 1 appearance and through wires hole 4 inwalls have the not

crust layer

2,3 of foaming, and the inside of type body 1 is cellular foaming body 5;

Crust layer

2,3 thickness are 0.5%～5% of type body 1 diameter D; Have between

crust layer

2,3 and the foaming body 5 by the extremely loose gradually transitional horizon 6 that foams of trickle foaming, make no obvious interface between

crust layer

2,3 and the foaming body 1.According to user's needs, the diameter D of spherical is the 6-45 millimeter, and the aperture d of through wires hole 4 is the 1-3 millimeter.Type body 1 material is a styrofoam.Type body 1 outer surface scribbles day lac varnish or coloured enamel.
