Abstract
The invention relates to a plastic life jacket used for ships and a preparing method thereof. The life jacket is prepared from, by weight, 80-120 parts of low-density polyethylene resin, 15-20 parts of azodicarbonamide, 3.5-4 parts of basic lead sulphate and 0.8-1 part of dicumyl peroxide. After the raw materials are mixed, blending and sheet cutting are performed, cooling and demolding are performed after expansion and foaming through heating, and sheets are cut off and sewed into a finished product. If a offshore person wearing the product falls into water, the person can rapidly float out the sea and the face of the person faces upward so that the objective of life saving is achieved. The life jacket is high in oxidation resistance, wear resistance and ageing resistance so that the service lifetime of a product is greatly prolonged.
Description
Technical field
The present invention relates to a kind of life jacket and preparation method thereof, and in particular to a kind of plastics lifejackets for ship and its preparation side
Method.
Background technology
Life jacket, also known as life vest, is a kind of clothing of rescue life, and the similar vest of design, is on ship, on aircraft
One of lifesaving appliance, wears with enough buoyancy, enables drowning people's head to surface.
At present, existing life jacket is all to cover one layer of textile on the surface of buoyant material, and in one layer of its surface attachment
The poor coating of pliability, compactness, across the sea persons falling in water long-time be immersed in water, the coating of life jacket is limited
System, it is neither reflective at night, can not be warming, so, easily miss and rescue good opportunity.Therefore how the deficiencies in the prior art are overcome
It is current material technology field problem demanding prompt solution.
The content of the invention
It is an object of the invention to provide plastics lifejackets for ship that a kind of pliability is good, adhesive force is strong and preparation method thereof.
For this purpose, the technical problem to be solved in the present invention is achieved through the following technical solutions.The invention provides a kind of
Plastics lifejackets for ship and preparation method thereof, is characterized in：It is made up of the raw material of following weight portion：Ldpe resin
80-120；Azodicarbonamide 15-20；Basic lead sulphate 3.5-4；Cumyl peroxide 0.8-1；Its preparation method include as
Lower step：(1) ldpe resin of dispensing, basic lead sulphate, cumyl peroxide will be carried out to put according to weight portion
Knead in mill, melting temperature is 70-80 DEG C, kneads 5-10min rear tabs, the size after pulling-on piece according to moulding press is cut out
Piece；(2) piece obtained in step (1) is put in foaming machine, is warming up to 100 DEG C, add azodicarbonamide, maintain 10-
20min, takes out foaming product after being water-cooled 5min, after arranging inspection, sewing panels obtain finished product.
Preferably, it is made up of the raw material of following weight portion：Ldpe resin 80；Azodicarbonamide 15；Alkali formula
Lead sulfate 3.5；Cumyl peroxide 0.8.
Preferably, it is made up of the raw material of following weight portion：Ldpe resin 120；Azodicarbonamide 20；Alkali formula
Lead sulfate 4；Cumyl peroxide 1.
Preferably, it is made up of the raw material of following weight portion：Ldpe resin 100；Azodicarbonamide 17；Alkali formula
Lead sulfate 3.8；Cumyl peroxide 0.9.
Preferably, in the step (2), melting temperature is 75 DEG C, kneads 10min.
Beneficial effects of the present invention：The present invention is kneaded after mixed material, and sheet material cuts, heated expanded foamed rear cooling
The demoulding, sewing panels finished product；Marine persons wear's this product falls into the water, and can quickly pay sea, makes the face of people towards day,
Reach the purpose of lifesaving.Antioxidation of the present invention, wear-resistant, ageing-resistant ability are strong, substantially prolongs the service life of product.
