In recent years, although some novel waterproof materials appear, the overall waterproof pattern mainly comprising a high polymer modified asphalt waterproof coiled material, a high polymer waterproof coiled material and a waterproof coating is not changed, and the waterproof coiled material is still in a leading position in the application of the building waterproof material in China and accounts for about 60 percent of the waterproof material.
The self-adhesive waterproof coiled material is a waterproof material which is prepared by taking self-adhesive rubber asphalt prepared from synthetic rubber such as SBS and the like, a tackifier, high-quality road petroleum asphalt and the like as a base material, taking a tough high-density polyethylene film or aluminum foil as an upper surface material and taking a strippable silicon-coated isolating film as a lower surface anti-adhesive isolating material. The isolating membrane used by the self-adhesive waterproof coiled material mainly comprises two types of PE and PET, and the thickness of the isolating membrane is generally 0.025-0.05 mm.
At present, most of waterproof coiled material isolating films on the market are prepared by using traditional thermosetting organic silicon release agents, but the release agents have the following defects: in the reaction process, micromolecular substances can be released, the film forming property and the stability of a release agent product are influenced to a certain degree, the crosslinking reaction speed of the release agent is low, and meanwhile, the release agent is mainly a solvent type and is diluted by toluene, gasoline and other solvents, so that the environment is polluted and danger is easy to occur. The release film produced by the release agent has unstable release force and residual adhesive force of only 70 percent, and a large amount of micromolecule substances are transferred into asphalt to influence the construction effect and quality.
Therefore, there is a need to develop a release film with low release force and high residual adhesion to meet the use requirements of the release film for waterproof roll.

The preparation method of the polyethylene release film for the free radical ultraviolet curing waterproof coiled material comprises the following steps:
(1) uniformly mixing acrylate-based polysiloxane, hyperbranched polysiloxane, an adhesive force additive, an antistatic agent and a photoinitiator to obtain a mixed material for later use;
(2) and (3) penetrating a polyethylene film on a coating machine, coating the mixed material in the step (1) in a nitrogen atmosphere after corona treatment with a corona value of 38 dyne, then carrying out ultraviolet curing, and rolling to obtain a product 6.
And (3) performance testing: the peel coating was tested for adhesion, peel value and subsequent adhesion.
Adhesion force: the adhesion of the cured coating to the carrier material was tested by vigorous rubbing with a thumb on the coating. In the case of insufficient tackiness, rubber-like shoulder fragments are formed. When the adhesiveness is good, no rubber-like shoulder fragments are generated even by vigorous rubbing. The test was performed by a trained panel. The evaluations were classified into a scale of 1 to 3.
Of these, grade 1 is very good scratch resistance and anchoring to the substrate. No shoulder fragments are detected for linear motion and subsequent circular motion at the same location.
Grade 2 is sufficiently good scratch resistance and adhesion to the substrate. The linear motion does not produce a shoulder breaker, but subsequent circular motion at the same location forms a shoulder breaker.
Grade 3 is insufficient scratch and tack resistance, even if linear motion produces shoulder chipping.
Peel value: the peel values were determined according to test protocol FTM 10 in FINAT manual version 8 (The Hague/NL, 2009) except that storage was carried out under pressure at 40 ℃. The adhesive tape is
And
the peel value depends on the adhesive tape, silicone and the cure of the silicone under test. Poorly crosslinked silicone release coatings produce significantly lower release values than similarly constructed well-crosslinked silicones.
And (3) subsequent adhesion: the subsequent adhesion was determined according to test protocol FTM 11 in The FINAT manual, 8 th edition (The Hague/NL, 2009) with The difference that The storage of The test adhesive strips in silicone contact was carried out for one minute and The standard surface was an untreated BOPP surface. The adhesive tape is
7475. Subsequent adhesion is a measure of silicone cross-linking. If there is a silicone component that is not polymerized and therefore migratable, the subsequent adhesion values decrease with increasing proportions of such components, values above 80% being considered acceptable.
The results of the performance tests on products 1-6 prepared in the above examples of the invention are shown in table 1.
TABLE 1 Performance test results for products 1-6
As can be seen from the above Table 1, the products 1-6 prepared by the invention all have good release force, aging release force and residual adhesive force, the product 1 of the invention has the best performance, the release force can be as low as 5.0cN/2.5cm in 20min, the aging release force is only 6.0cN/2.5cm in 24h, and the residual adhesive force is as high as 99%.
