Abstract
The invention discloses an HDPE (high-density polyethylene) coloured film for increasing a friction coefficient. The HDPE coloured film comprises a first co-extrusion film layer, a second co-extrusion film layer and a co-extrusion modified material film layer, wherein the first co-extrusion film layer is arranged above the second co-extrusion film layer, and the co-extrusion modified material film layer is arranged below the second co-extrusion film layer. The HDPE coloured film for increasing the friction coefficient, provided by the invention, has the advantages that the friction coefficient is high, a mechanic and temperature-resisting property is remarkable, blending modification of a polarity material is adopted, the adaptation is good, and the manufacture is convenient.
Description
Technical field
The present invention relates to membrane material field, particularly relate to a kind of HDPE Coloured film that increases coefficient of friction.
Background technology
In the fields such as packing, printing and building waterproof coil, often use various HDPE Coloured films, Coloured film is because adding the look mother of 5%-15%, and in look mother, contain the low-friction coefficient materials such as dispersant, lubricant, the skin-friction coefficient of film is reduced, at 0.10-0.15, after the surface of film contacts with steel rider, be in operation and easily cause and skid, as in coiled material is produced, the speed of rolling only has 20-30 rice/min, speed is slow, thereby causes rolling efficiency low.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of HDPE Coloured film that increases coefficient of friction, by HDPE layer is set, guarantees effective coating of mould release; By being set, material provides good mechanical strength and heatproof characteristic for HDPE, mPE and look mother; By blending and modifying layer is set, improve coefficient of friction, avoided the reduction of the strength of materials simultaneously; Have that coefficient of friction is high, mechanics and resistance to temperature performance outstanding, adopt same polarity material blending and modifying, the feature such as adaptability is good, easily manufactured, the scope of application is wide.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of HDPE Coloured film that increases coefficient of friction is provided, comprise: the first co-extrusion rete, the second co-extrusion rete and co-extruded modified film layer, described the second co-extrusion rete top is provided with the first co-extrusion rete, described the second co-extrusion rete below is provided with co-extruded modified film layer, described the first co-extrusion rete is DHPE layer, and described the second co-extrusion rete is for mixing co-extrusion rete.
In a preferred embodiment of the present invention, described DHPE layer is provided with coating.
In a preferred embodiment of the present invention, the co-extrusion material of described mixing co-extrusion rete is HDPE, mPE and look mother's composite material, and described HDPE, mPE and look mother's mixed proportion is 7:3:0.6.
In a preferred embodiment of the present invention, described material modified layer material is HDPE, PP, LLDPE, TPO, wherein one or more of color masterbatch.
In a preferred embodiment of the present invention, the HDPE Coloured film thickness of described large coefficient of friction is 0.04mm, and described coefficient of friction is 0.18-0.22.
