Description
The present invention is a kind of electrostatic prevention, compound package material, relates to the preparation of chemical materials.
At present; the production of dangerous material and electronic product; transportation; in the storage process; can its effective packing not only be related to goods itself and stand intact; the more important thing is the safety of direct influence transportation; this class dangerous material goods all belongs to inflammable; explosives; producing; store; in the transportation; because friction; bump; the influence in external electrical field and magnetic field; be easy to generate static, cause the inner somewhere of dangerous material electrostatic potential to increase, thereby produce spark discharge; have influence on the safety of goods; therefore, select and the use packing, satisfying under original engineering factor requirement; also essential emphasis is considered the electric conductivity of material; use conductivity water temperature and depth height; the conductive material dangerous goods in packaged form goods that electrical resistivity is low prevents the generation and the accumulation of static, plays the safety effect of protection goods.And the packing of dangerous material use the earliest is application type, be about to electrically-conducting paint and coat on the plastic sheeting, and the surface resistivity of this material is 10
10-12Ω, the electric conductivity extreme difference can not be done antistatic packaging material; A kind of packing of dosing type had appearred again afterwards, be with conductive material as metal powder, carbon black, conductive fiber, conductive agent etc., dose in plastics, blow molding, this material cost height, pulling strengrth is low, anti-soak properties are poor, and are therefore also undesirable.
The objective of the invention is to overcome above-mentioned deficiency, and a kind of composite bed packing with conductive layer are provided, and can prevent the generation and the accumulation of static, can guarantee the safe reliability in the dangerous material goods transport.
Above-mentioned purpose of the present invention is realized by following technical scheme: this novel electrostatic prevention, compound package material is formed by the compound coating of four layer materials, internal layer is hot sealing layer, form by polyethylene, inferior internal layer is the mechanical strength layer of being made up of polyester or polypropylene, inferior skin is by second, but the coating layer that propylene copolymer forms, outer conductive layer for electrically-conducting paint formation, electrically-conducting paint is by 2～20% EVA, 3～20% conductive black, 50～80% water, 0.3～1% sodium carboxymethyl cellulose, 0.5～2% emulsifying agent, 0.2～0.5% aging inhibitor, 0.3～0.8% rheological agent, 0.1～0.6% defoamer and 0.3～0.5% anti-freeze additive are formed.When preparing this material, at first prepare electrically-conducting paint, the EVA adhesion agent is added in the reactor evenly stir earlier; Then conductive black, water, sodium carboxymethyl cellulose, emulsifying agent, aging inhibitor, rheological agent, defoamer and anti-freeze additive are once added in the reactor, be heated to 40～50 ℃, stir and be electrically-conducting paint after 2～3 hours; The method of electrically-conducting paint with roller coat is applied on second, the propylene copolymer film substrate, coating temperature is 80～100 ℃, but obtains the laminated film of coating layer and conductive layer again; It is compound then but the laminated film of mechanical strength layer and coating layer and conductive layer to be carried out heat, obtains the mechanical strength layer, but three layers of laminated film of coating layer and conductive layer; But three layers of laminated film with polyethylene foil sealing layer and mechanical strength layer coating layer and conductive layer are coated with compound more at last.
Characteristics of the present invention:
1. the electrostatic prevention compound package material has high conduction performance, and the electrostatic defending to the hazardous materials packing can effectively be provided;
2. electrostatic prevention compound package material, good mechanical performance can satisfy the mechanical strength packing requirements of hazardous materials;
3. physics, chemical reaction do not take place in products to be packaged in the electrostatic prevention compound package material, can be directly used in contact packing;
4. the ageing-resistant performance excellence of electrostatic prevention compound package material can reach normal temperature and deposit more than 15 years.
