Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention belongs.
The pre-paved anti-sticking type self-adhesive film waterproof coiled material has a layer of 0.7-1.2 mm thick polymer sheet (such as HDPE sheet) as a base material, a 0.25-0.50 mm thick polymer self-adhesive layer is coated on the surface of the base material in a hot melting way, and then a silicon isolation film or quartz sand is coated on the surface of the polymer self-adhesive film to play a role in sticking resistance. The anti-sticking layer of the coiled material has great influence on the production and application of the coiled material, is firstly used for preventing sticking, and does not make self-adhesive adhere to the back of a sheet material in the production and winding process of the coiled material; secondly, the pollution of dust, water, silt and the like to the surface of the self-adhesive can be effectively prevented in the process of paving and pasting the coiled material, and the influence of environmental ultraviolet rays on the aging of the self-adhesive is effectively prevented; and can form good bonding with post-cast concrete again. At present, the quartz sand anti-sticking layer is generally adopted. The particle size of the quartz sand is 30-60 meshes, the thickness of the anti-sticking sand layer is about 0.2-0.5 mm, and the quartz sand is spread on the surface of the self-sticking glue in the gluing process and then is compounded on the surface of the self-sticking glue through rolling. If not roll-in, the grit dead weight is difficult firmly to adhere on the self-adhesive surface, drops easily, but roll-in again will cause the damage to the polymer sheet, leads to the sheet tensile strength to descend. In addition, as the quartz sand is adhered to the surface of the self-adhesive glue and is adhered to the surface of the concrete after reacting with the post-cast concrete, the contact surface of the self-adhesive glue and the post-cast concrete is obviously reduced, and the adhesion between the prepared self-adhesive glue film waterproof coiled material and the concrete is reduced. Moreover, the gaps are formed among the quartz sands, when the coiled material is paved on a working surface, the coiled material is very likely to be polluted by the environment such as dust, muddy water and the like, and the pollutants enter the surface of the self-adhesive glue through the gaps among the quartz sands to pollute the self-adhesive glue, so that the adhesiveness between the self-adhesive glue and the post-poured concrete is further reduced. Therefore, the inventor of the invention realizes that the anti-sticking layer which replaces quartz sand can play an anti-sticking role, well protect the self-adhesive glue from being polluted by water, dust, silt and the like, prevent ultraviolet rays from influencing the self-adhesive glue, react with post-poured concrete and improve the bonding force between the self-adhesive glue and the post-poured concrete, and has very important significance.

In one embodiment of the present invention, the coating comprises: 8-12 parts of polyvinyl alcohol, 55-65 parts of water, 11-13 parts of vinyl acetate-ethylene copolymer emulsion, 7-9 parts of acrylic polymer emulsion and 2-4 parts of titanium dioxide.
In one embodiment of the invention, for example, the polyvinyl alcohol has at least one of the following properties: the alcoholysis degree is 87-89, the pH value is 5-7, and the average polymerization degree is 1700. For example, PVA17-88, a commercially available product of Shanxi, Inc. can be used as the polyvinyl alcohol. The polyvinyl alcohol has good water solubility, good film forming property, good chemical stability, good oil resistance and good cohesiveness with concrete, contains a large amount of hydroxyl on a molecular chain, can participate in hydration reaction of the concrete and then is completely dissolved in a product, and improves the compactness of the surface of the concrete.

For example, the vinyl acetate-ethylene copolymer emulsion may be a VINNAPAS 920 emulsion, a commercial product of WACKER chemical company (WACKER). The vinyl acetate-ethylene copolymer emulsion has good water resistance, good initial adhesion and cohesiveness, good flexibility and good weather resistance, the molecular structure contains carboxyl, the vinyl acetate-ethylene copolymer emulsion can participate in the hydration reaction of concrete, well bonds the molecular chain of the concrete, and improves the cracking resistance and the compactness of the concrete; the emulsion is acidic, has good solubility with the water solution of polyvinyl alcohol PVA17-88, can offset the water solubility of polyvinyl alcohol, and improves the water resistance of the whole coating film.
In one embodiment of the present invention, for example, the acrylic polymer emulsion has at least one of the following properties: 60 percent of solid content, 6.0 of pH value, 1000mpa & s of viscosity and 40 ℃ below zero of glass transition temperature Tg. For example, the acrylic polymer emulsion may be obtained as a commercial product of plexitol D5511 from shanghai sumama chemical co. The acrylic polymer emulsion has good water resistance, good elasticity, good ultraviolet aging resistance, good low-temperature flexibility, good stain resistance and acidity, can be well dissolved with polyvinyl alcohol, can offset the water solubility of the polyvinyl alcohol, provides excellent elasticity for a donor system, can adapt to the bending of self-adhesive without cracking, can participate in the hydration reaction of concrete, and improves the compactness of the surface of the concrete.
In one embodiment of the invention, for example, the titanium dioxide is rutile titanium dioxide. The titanium dioxide can be commercialized product R706 titanium dioxide of DuPont company, and can improve the ultraviolet aging resistance of the system.
In one embodiment of the present invention, for example, the water is deionized water, distilled water, or high purity water. Water of the above-mentioned kind contains only few impurities and does not adversely affect the properties of the product.

Above-mentioned antiseized layer can prevent effectively that above-mentioned "shop in advance to turn over when gluing type self-adhesive film waterproofing membrane" rolling, polymer self-adhesion glue layer and polymer sheet back adhesion, and the polymer self-adhesive that can effectively protect waterproofing membrane simultaneously is not influenced by water, dust, silt etc. at the construction shop paste in-process. And the anti-sticking layer can react with the post-cast concrete, so that the compactness of the concrete surface is improved, and the bonding force between the post-cast concrete and the polymer self-adhesive is improved. The anti-sticking layer (weather-proof coating layer) can completely replace the prior quartz sand anti-sticking layer.

The polymer sheet and the self-adhesive were the same as those used in (1) and (2) of example 2, and the quartz sand was a commercially available product having a particle size of 30 to 60 mesh.
The coating equipment adopts a macromolecular self-adhesive film waterproof coiled material coating machine produced by Zhejiang Ruian Jiayuan mechanical equipment Limited company for coating, the glue melting temperature is 170-180 ℃, the coating speed is 5-6 m/min, the coating thickness is 0.25-0.35 mm, the anti-sticking quartz sand is automatically spread by an online machine, and the using amount is 1000-1500 g/m2And automatically rolling.
(2) The performance of the coil stock obtained in example 3 was compared with that obtained in example 4(1) above (adhesion to post-cast concrete) using the pre-laid coil stock standard of GB/T23457-2009, with the following results.
From the test results, it can be seen that the coating of the present invention forms a coating film release layer having more excellent adhesion to concrete than the conventional silica sand release layer under any test conditions.
The above description is intended to be illustrative of the present invention and not to limit the scope of the invention, which is defined by the claims appended hereto.
