Problems solved by technology

[0002] At present, the aquaculture industry generally uses a kind of EPS foam float. After the EPS plastic is foamed at a high rate, its tear strength is low, which leads to easy rupture and limits its service life.
Especially in marine aquaculture, due to the strong impact of the waves and the friction with the tied ropes, it is more likely to be broken, and after the breakage, the pieces are separated and the volume is relatively small, making recycling quite difficult, so it is very harmful to the marine environment. Serious white pollution is coming

Embodiment 1

[0035] For marine mussel culture, take the commonly used foam float as an example. The appearance of the float is a cylindrical float with two arc-shaped ends, the diameter is Ф500mm, and the total length of the cylinder is 800mm. The shell coating thickness is preferably 0.8-1.0mm. The shell coating material is PS material, and the inner core is EPS foam material. The specific coating process includes the following steps:

[0036] 1. Material selection: PS raw material performance selects high-impact grade, grade selects extruded sheet grade, granular raw material.

[0037] 2. Sheet production: The PS raw material is made into a sheet through a sheet forming machine. The thickness of the sheet is 2-2.4 times the thickness after blistering, the width of the sheet is 1100mm, and the temperature of the extrusion molding die is 180-200°C.

[0038] 3. Blistering: the sheet is made into two semi-elliptical or hemispherical shells 33 through a blister forming machine, the forming mo...

Embodiment 2

[0047] According to the situation of embodiment 1, the specification of the floating ball is reduced, the diameter is 300mm, the total length of the cylinder is 600mm, the thickness of the outer shell is also 0.5-0.6mm, the material of the outer shell is PVC and ABS blended plastic alloy, and the inner core For EPS foam materials, the specific coating process includes the following steps:

[0048] 1. Proportion by mass percentage: PVC64%, ABS20%, CaCo 3 10%, compound stabilizer 2%, dioctyl fat 3%, lubricant 0.5%, black carbon powder 0.05%-0.1%.

[0049] 2. The stirred mixture is made into a sheet through a twin-screw sheet forming machine. The thickness of the sheet is 2-2.4 times the thickness of the blister, the width of the sheet is 700mm, and the temperature of the extrusion die is 170-190°C.

[0050] The steps from 3 to 6 are the same as those in Implementation 1.

[0051] Test for the foam buoy made in embodiment two:

[0052] 1. Drop the foam float from the 10m three...

Abstract

The invention relates to a bubble floating ball and a manufacturing process thereof. The bubble floating ball comprises an inner ball and an outer ball, wherein the inner ball is produced from plasticfoam materials, the outer ball is produced from thermoplastic plastic materials, packages the inner ball and is formed by lapping half-elliptical or half-spherical shells, and folding edges are arranged at the lapped parts. The bubble floating ball comprises the outer ball and the inner ball, so that the performance of the bubble floating ball is improved; the folding edges are bent towards the same direction, so that the surface of the floating ball is smooth, and the floating ball is unlikely to be cut off when being tightly bound by a rope or net bag in use; and the impact strength of a gap in a welding part can be improved, so that the situation that the bubble floating ball is broken by the friction of a binding rope is avoided, and meanwhile, the problems that broken bodies are difficult to be recycled, and the ocean pollution is caused are avoided.

Description

technical field [0001] The invention relates to a foam floating ball and a manufacturing process thereof, belonging to the field of chemical technology. Background technique [0002] At present, the aquaculture industry generally uses a kind of EPS foam float. After the EPS plastic is foamed at a high rate, its tear strength is low, which leads to easy rupture and limits its service life. Especially in marine aquaculture, due to the strong impact of the waves and the friction with the tied ropes, it is more likely to be broken, and after the breakage, the pieces are separated and the volume is relatively small, making recycling quite difficult, so it is very harmful to the marine environment. Serious white pollution came. Therefore, there is an urgent need for a new type of floating ball that can improve the service life and can be easily recovered after being broken to replace the traditional floating ball. Contents of the invention [0003] Aiming at the above disadvan...
