Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that when the prior art self-adhesive waterproof membrane is used, the isolation film is easy to separate from the asphalt when using PET film, and is greatly restricted by seasons and environments. The defect of high cost; when using PE film, it is easy to cause wrinkles and unevenness on the surface of the coiled material, which will affect the appearance and waterproof effect of the coiled material; Self-adhesive waterproof membrane with MPET pattern and its preparation method, which is separated, is less restricted by seasons and environments, improves the appearance quality of the membrane, and has no obvious recovery of pattern deformation after heat-coating

Embodiment 1

[0023] The inner material stabilizer is a recreational of antioxidants 1010 and antioxidants 168. The proportion of the two is 1: 1;The ratio is 1: 1.2.

[0024] MPET pattern isolation membrane preparation steps are as follows:

[0025] 1) Preparation of inner material particles

[0026] Put PET, average PP, inner material compatibility agent, and inner material stabilizer into high -speed mixer at a high -speed mixer. The material temperature reaches 110 ° C and then mixes at low speed.There are exhaust holes).The above -mentioned first mixing materials are mixed with dual screw extruders with a vacuum pump.

[0027] 2) Preparation of outer material particles

[0028] Put PET, PE, outer material compatibility agent and outer material stabilizer into a high -speed mixer at a high -speed mixing at a high speed until the temperature is 100 ° C, then stir at low speed for 5 minutes.The above -mentioned first mixing materials are mixed with dual screw extruders with a vacuum pump.

Abstract

The invention specifically relates to an MPET (metallized polyethylene terephthalate) pattern isolating film for a self-adhesive waterproof coiled material and a preparation method thereof. The isolating film is formed by co-extrusion casting of three layers of material, namely an outer layer, an inner layer and a core layer; the inner layer of the material is formed by blending the following components by weight ratio and performing twin-screw granulation: 75-85% of casting grade PET (polyethylene terephthalate), 10-20% of homopolymerized PP (polypropylene), 3-5% of inner-layer material compatilizer and 0.5-1% of inner-layer material stabilizer; the outer layer of the material is formed by blending the following components by weight ratio and performing twin-screw extraction and granulation: 70-80% of casting grade PET, 15-25% of PE (polyethylene), 3-5% of outer-layer material compatilizer and 0.5-1% of outer-layer material stabilizer; and the core layer is formed by blending the following components by weight ratio and performing the twin-screw granulation: 85-90% of casting grade PET, 5-10% of PE, 3-5% of core-layer material compatilizer and 0.3-0.5% of core-layer material stabilizer. The MPET pattern isolating film disclosed by the invention has the advantages of low cost, easiness in stripping, difficulty in separation from asphalt, small seasonal and environmental restriction, capability of improving the appearance quality of the coiled material, and non-obvious deformation recovery of a pattern after heat coating.

Description

Technical field [0001] The invention is a manufacturing method for modified polyester membranes and patterns and anti -counterfeiting. It specifically involves a self -adhesive waterproof coil and its MPET pattern isolation membrane and its method. Background technique [0002] At present, my country's self -adhesive waterproof coil consumes nearly 10,000 tons per year, mainly PE and PET membranes. Among them, the PET membrane is mostly imported and recycled film. There is no guarantee such as quality), plus the new PET membrane, accounting for about 1 / 3. Because the PET membrane curved modulus is large, it is easy to separate from the self -adhesive asphalt. At the same time, the seasons are different or different temperature. ; PE isolation membrane is likely to cause rolling surface wrinkles to affect the appearance and waterproof effect of the coil.In response to the limitations of these aspects, there are currently imported improved patterns in the market, but the temperatu...
