Abstract
The invention relates to an oxygen barrier composite material and a preparation method thereof, and belongs to the technical field of composite materials. The oxygen barrier composite material comprises the following components in part by weight: 0.1 to 50 parts of glass fibers, 40 to 80 parts of polyolefin and 0.01 to 20 parts of aid. The oxygen barrier composite material has the advantages that: a pipe base material and an oxygen barrier composite material layer are not required to be glued by hot melting and can be fused together to be subjected to molecular bonding; meanwhile, the influence of temperature or humidity increase on the barrier property of the oxygen barrier composite material is eliminated.
Description
Technical field
The invention belongs to technical field of composite materials, be specifically related to a kind of resistance O compoiste material and preparation method thereof.
Background technology
Barrier material is exactly to have the material that stops the gas molecule through characteristic, and EVOH numerical value (ethylene-vinyl alcohol copolymer) is a kind of known barrier material at present, is widely used in soft or hard food, sauce, tomato-sauce, meat, tealeaves and cosmetic package field.
Any material all has its suitability, and the EVOH resin is under the lower condition of relative humidity, and barrier is only second to aluminium foil.But owing to contain the polar functional base on the EVOH molecular resin key; Be easy to environment in water molecules; So wet quick property is prone to moisture absorption by force; Barrier property sharply descends after the moisture absorption of EVOH resin; For overcoming the drawback that barrier property lost efficacy after a large amount of moisture absorptions of EVOH resin; At present packaging industry is clipped in multilayer in the middle of wet film at a distance from wet plastic film composite methods food year with the EVOH barrier layer, intercepts validity period to reduce moisture absorption, to prolong.However, also can only prolong packing material about 18 months storage tives.
At present, because limited aspect special-purpose barrier material selection, the plastic pipe industry is generally all transferred to the good barrier properties of EVOH resin the oxidation prevention layer material of hot water or cold water, heating, air-conditioning system resistance oxygen tubing, so that tubing possesses resistance oxygen function.
In addition because the EVOH resinous molecular structure has acute functional group; And the tubing base-material is not with, thus two kinds of materials do not melt mutually, therefore; Must adopt the hot melt adhesive Vilaterm to connect the skill acid anhydrides during use, with surface, internal layer or the centre of EVOH resin bond to tubing as tackiness agent.General oxidation prevention layer and oxidation prevention layer both sides hot melt adhesive total thickness have only 0.015～0.020mm; So precision and processing requirement to equipment when tubing is made are very strict; Production process control difficulty is big; Unavoidably cause EVOH oxidation prevention layer, hot melt adhesive adhesive layer thickness deviation big and uneven thus; And EVOH oxidation prevention layer, hot melt adhesive bonding break material phenomenon; Also can cause resistance oxygen pipe mechanical property and resistance oxygen effect to descend in case lack material, cause tubing can not reach the desired result of permanently effective resistance oxygen.
Summary of the invention
The objective of the invention is provides a kind of new resistance O compoiste material in order to solve the problems referred to above of present resistance O compoiste material.
Technical scheme of the present invention is following:
