Abstract
The invention discloses an EPE foam for a life jacket. The EPE foam is prepared by carrying out melt mixing and extrusion molding in an extruder on the following components and materials by weight: 80 to 85 parts of an LDPE resin particle, 18 to 20 parts of a foaming agent, 1.5 to 2 parts of a nucleating agent and 0.2 to 0.5 part of an anti-shrinking agent, wherein the LDPE resin particle is a low density polyethylene resin particle or a mixture of the low density polyethylene resin particle and a reclaimed EPE material, the foaming agent is butane, the nucleating agent is talcum powder or ultrafine calcium carbonate, and the anti-shrinking agent is glycerin monostearate. The EPE foam for a life jacket prepared in the invention is a novel, light-weight, transparent, non-toxic and odorless plastic material and has the advantages of good shock absorption, impact resistance, heat sealability, no toxicity, no odor, moisture resistance, corrosion resistance and transparency.
Description
Technical field
The invention belongs to the PE Foam technical field, relate to a kind of PE Foam foam, be specifically related to a kind of vestlifejacket PE Foam foam.
Background technology
The polyethylene foam cotton is the non-crosslinked unicellular structure, claims again the EPE PE Foam, is a kind of wrapping material of novel environment friendly, produces countless separated foams by Low Density Polyethylene through physical blowing and consists of.It is frangible to have overcome common foamed glue, distortion, the shortcoming that recovery is poor, has the water proof protection against the tide, shockproof, sound insulation, insulation, plasticity is good, toughness is strong, reconstituted circularly, environmental protection, the plurality of advantages such as crashworthiness power is strong, also has good chemical resistance, be the ideal substitute of Traditional Packing material, be widely used in electronic apparatus, instrument, computer, sound equipment, medicine equipment, the industry control cabinet, hardware and lamp decoration, artwork, glass, pottery, household electrical appliances, spraying, the furniture family property, the high-grade frangible Gift Package such as drinks and resin, hardware, toy, melon and fruit, the internal packing of leather shoes, the packing of the multiple products such as daily necessities.After adding colored antistatic agent and fire retardant, more aobvious its remarkable performance, not only exquisite appearance, and effectively stop static and combustion EPE PE Foam also be used in a large number the cushions of handbag case and bag, the floatation device of industrial sound insulation, lagging material, agricultural lagging material, aquaculture, the protective pad of sports goods, the operation at sea buoyant apparatus, the floor finiss in family, hotel, liner etc.Its tubing is used for air-conditioning, perambulator, toy for children, family property, the industries such as hot-water heating ventilation in a large number.The adhesive article of PE Foam and various fabrics is the good interior finish materials in various vehicles and room, the composite product of PE Foam and aluminium foil or metallized film has excellent anti-UV and IR ability, be some chemical industry equipment refrigerator chambers and camping equipment automobile sun-shading must articles for use.
Vestlifejacket (a life jacket) claim again life waistcoat, is a kind of clothes of giving first aid to life, and design class adopts nylon facing material or chloroprene rubber (NEOPRENE) like vest, buoyancy material or inflatable material, and light reflecting materials etc. are made.Normal operation year is limited to 5-7, is one of survival equipment on the ship, on the aircraft.Be generally vest type, make with porous plastics or cork etc.Be through and have enough buoyancy with it, drowning people's head can be surfaced.
Summary of the invention
