The exposed water-based asphalt-based waterproof coating material comprises anionic emulsified asphalt, a polymer emulsion, a filler, and an auxiliary agent, wherein the anionic emulsified asphalt is prepared by melt-blending matrix asphalt with a composite weather-resistant additive and then emulsifying the resulting blend.

By introducing the antioxidant and the ultraviolet absorbent into the anionic emulsified asphalt, the present invention improves the stability of a waterproof coating material system and avoids a demulsification phenomenon; moreover, by using a weather-resistant polymer emulsion in combination with a filler and an auxiliary agent, the weather resistance of the prepared waterproof coating material is greatly improved; furthermore, by means of the protective effect and the sunlight reflecting effect of white sintered sand adhered to a surface of the coating material, the waterproof system can be used as an exposed product for waterproof construction of buildings that have been in exposed environments for a long time.

Abstract

The present invention relates to a high-barrier hot-melt adhesive film, a preparation method therefor, and a composite board. The hot-melt adhesive film comprises a first adhesive layer used for bonding with PVC, a second adhesive layer used for bonding with a metal, and a transition layer provided between the first adhesive layer and the second adhesive layer. Raw materials of the first adhesive layer comprise a copolyester and styrene-acrylonitrile-glycidyl methacrylate; and raw materials of the transition layer comprise nylon, maleic anhydride-grafted polyethylene and glass flakes. Redesigning the raw material formulas of the first adhesive layer and the transition layer of the hot-melt adhesive film in the present invention enables the hot-melt adhesive film to have better plasticizer barrier performance, and a better high-temperature peel strength and a peel strength retention rate under more severe thermal aging conditions. Thus, a composite board obtained by bonding a metal and PVC with the hot-melt adhesive film can be used in more severe working conditions, and is especially suitable for the requirement on peel strength under the condition of long-time use at perennially high outdoor temperatures, such as in equatorial areas.

Abstract

The present invention relates to a pre-applied polymer waterproofing sheet and a preparation method therefor. The pre-applied polymer waterproofing sheet comprises a base material layer, an adhesive layer and a protective coating which are sequentially stacked, raw materials of the protective coating comprising an acrylic resin emulsion having a core-shell structure, wherein the glass transition temperature of a shell polymer of an acrylic resin is greater than the glass transition temperature of a core polymer, and the theoretical glass transition temperature of the resin used by the acrylic resin in which all monomers are polymerized into an irregular copolymer is designed to be 0-20°C. Research finds that the acrylic resin having the core-shell structure using different glass transition temperatures is used as a film forming material of the protective coating of the pre-applied polymer waterproofing sheet, so that the protective coating is not easy to crack after the pre-applied polymer waterproofing sheet is rolled. Moreover, using at high temperature or immediately rolling after the sheet is produced can avoid the problem that the sheet is difficult to unroll due to adhesion between the protective coating and the base material layer on the back surface.

After long-term use, the peel strength of a composite plate of a metal and PVC bonded by the hot melt adhesive film is basically not attenuated.

Firstly, the photovoltaic support is mounted on the base layer, and then the thermal insulation layer, the leveling layer and the waterproof layer are constructed. When a photovoltaic module is mounted, the photovoltaic module is directly mounted on the photovoltaic support, preventing damage to the waterproof layer caused by piercing; a waterproof joint is also easy to process, and the waterproof reliability is increased. In addition, the waterproof layer is exposed, so that if a leakage problem occurs later on, a thick coating repair can be directly performed without removing a roof component or structure, so that maintenance is convenient and economical.

The raw materials for the waterproof coating include asphalt, a compatibility agent, a dewatering agent, a catalyst, a filler, and an end-capped polyurethane prepolymer, wherein the end-capped polyurethane prepolymer is obtained by reacting a compound of formula (I) with a polyurethane prepolymer, and the end-capped polyurethane prepolymer does not comprise a terminal isocyanate group. The waterproof coating is prepared by firstly preparing the end-capped polyurethane prepolymer, then mixing same with the remainder of the raw materials. The waterproof coating can be used in a construction operation of applying an asphalt waterproof roll to a cement base. The preparation process of the waterproof coating is safe. In use, the waterproof coating can be directly coated onto a cement base having a high water content and, upon hydrolysis, will react with the silicate in the cement, which enhances the bonding force to the wet base. The waterproof coating also has excellent bonding strength to the asphalt waterproof roll, and in particular, has fast surface drying time and hard drying time, and a moderate viscosity. Use of the waterproof coating allows the elimination of a temperature-increasing step before starting a construction operation, which facilitates on-site construction.
