Problems solved by technology

The biggest problem with glue-coated protective film is: affected by time and ambient temperature, there will be problems of glue layer transfer, and there are many production processes and high production costs
Moreover, most of the adhesive films cannot be printed, because there will be ink transfer, which cannot meet the customer's requirements for the printing performance of the protective film.

Embodiment Construction

[0027] The one-time forming non-adhesive cold adhesive protective film of the present invention selects the following raw materials:

[0028] 1# FC801, isotactic homopolypropylene

[0029] Contains 300ppm of anti-sticking agent and 800ppm of slip agent. TM (melt point) = 162

[0030] °C, MI=8.0

[0031] 2# 1002YB, linear low density polyethylene

[0032] TM (melt point) = 120°C, MI = 2.0

[0033] 3# 5371,POE

[0034] TM (melt point) = 64°C, MI = 5.0

[0035] 4# CW-1, tackifying resin

[0036] Ring & Ball softening point=115℃

[0037] 5# FD0270, low density polyethylene

[0038] TM (melt point) = 115°C, MI = 2.4

[0039] The weight composition of film corona layer / intermediate layer / adhesive layer structural component is (A / B / C) following four kinds:

[0040] 1. 1#100% / 2#75%+5#25% / 2#35%+3#50%+4#15%

[0041] Its meaning is: thin film corona layer: 1#100% (1# component weight accounts for 100%)

[0042] Middle layer: 2#75%+5#25% (2# component accounts for 75% by weigh...

Abstract

The invention discloses a once-forming non-gelatinizing cold sticking protective layer, which comprises the following parts: corona treatment layer, mesosphere, adhesive coating, wherein the corona treatment layer consists of isotactic homopolymerization polypropylene, polypropylene , adhesion preventives and slip additive; the mesosphere consists of polyethylene with low density, linearity polyethylene with low density; the adhesive coating consists of linearity polyethylene with low density, POE and tackifier.

Description

technical field [0001] The invention relates to a cast co-extruded protective film for protecting industrial plates, specifically a non-adhesive cold-adhesive protective film, which can be used for PC plates, PMMA plates, aluminum-plastic plates, metal plates, refrigerators, and washing machines Other color steel plates and so on. Background technique [0002] At present, the protective films used for the above-mentioned boards in China are mainly heat-adhesive protective films and glued protective films. The production process of thermal adhesive protective film is produced by blow molding or casting method. When pasting, the plate needs to have a certain temperature before the protective film can be pasted on. However, the above-mentioned plate is produced at a low temperature and cannot be pasted. It must be reheated. Therefore, thermal adhesive protective films are of limited use. The production process of the glued protective film is: first produce a non-adhesive film...
