Abstract
The method includes following steps: after being dissolved by acetic ether, polyurethane adhesive is coated on plastic film, coating weight 2 - 4g/m2, and passing through drying tunnel with three tracks; compounding metal foil with plastic film, placing it in oven for 20-30 hr. under temperature 45-55 deg.C so as to obtain metal plastic composite foil. The polyurethane adhesive is prepared from main agent polyether glycol, firming agent of aromatic isocyanate. Mass compounding ratio of main agent, firming agent, and acetic ether is 10 :1 - 4 :8 - 20. Advantages are: good surface quality, even thickness in each layer, concurrent bonding property, large adhesion, and tensile strength, high extensibility, low resistivity, and good shielding properties. The invention provides condition for producing communication line in high performance.
Description
(1) technical field
The present invention relates to a kind of preparation method of metal plastic composite foil, described metal plastic composite foil mainly is the shielding material use as communication cable.
(2) background technology
Because country payes attention to infrastructure construction, as the transformation of urban and rural power grids, the development of information superhighway, the rapid development of telecommunications, the update of power consumption equipment and the requirement of energy-conservationization etc., will be to kind and the level constantly proposition new requirement of communication with electric wire.
At present, China only has 30% cable kind to reach the level that the international market can be accepted and participate in the competition, and also has 70% cable kind to be badly in need of improving product level and class.The decisive factor that improves cable products is to improve product shielding material quality and technical merit.Because production technology falls behind, product resistivity height, tensile strength are little with plastic-aluminum combined carries product in used in the market shielding, the bad adhesion of aluminium foil and plastics, the shielding properties instability, thus cause the quality of telecommunication cable and class to can not get raising.
For satisfying the requirement of modern science and technology high speed development, for communications cable industry provides the high-performance shielding material, change the present cable shield material product of China and be in backward state, improve the localization rate of electronic devices and components communications cable industry and the competitiveness of international market, press for current production technology is improved.
(3) summary of the invention
For solve existing shielding with plastic-aluminum combined product owing to the technology backwardness causes that communications cable resistivity height, tensile strength are little, aluminium foil and plastic bonding is poor, the unsettled deficiency of shielding properties, the invention provides a kind of preparation method of metal plastic composite foil, gained metal plastic composite foil surface quality is good, each layer thickness is even, adhesive property is consistent, adhesion is big, tensile strength is big, elongation is high, resistivity is low, advantages of good shielding performance.
For reaching goal of the invention the technical solution used in the present invention be:
