Problems solved by technology

However, these plasticizers usually tend to migrate out onto the surface of the material during product use and / or further processing
This migration has several adverse effects
On the one hand, migration of plasticizers from plastic materials can lead to hardening and / or increased brittleness of the plastic material itself, thereby affecting its use function
Migration of plasticizers, on the other hand, causes the resin in the polymeric coating to swell and soften, reducing the stain and / or blocking resistance of the surface of the coating

preparation example Construction

[0087] The preparation of the water-based coating composition of the present invention can be realized by any suitable mixing method known to those of ordinary skill in the art. For example, a waterborne coating composition can be prepared by adding the waterborne latex, filler and additives to a container, and then stirring the resulting mixture until homogeneous. Alternatively, the waterborne coating composition can be prepared by mixing some of the additional additives with the filler, and then adding the waterborne latex and the remainder of the additional additives to form a homogeneous mixture. Additional water can be added during preparation of the aqueous coating composition, if desired. Additional water should be added to the total weight of the aqueous latex.

[0088] The above-mentioned water-dispersible polyurethane-based aqueous coating composition of the present invention can be applied by conventional methods known to those skilled in the art, such as by spray ...

[0116] Embodiment 1-2: Preparation of water-dispersible polyurethane-based aqueous coating composition

[0117] Under low-speed stirring at 350-450rpm, add 200g of deionized water, thickener HMHECPlus330, dispersant N40, defoamer SN154, pH regulator anhydrous sodium carbonate to the stirrer, and stir for 5-10 minutes until uniform . Then add filler rutile titanium dioxide, heavy calcium carbonate and diatomaceous earth to the mixture, and stir at 800-1250rpm at high speed for 20-30 minutes to form a uniform slurry. Finally, add defoamer 122NS, 7360 water-based polyurethane dispersion, SF-506 acrylic emulsion, silane coupling agent, BIT20 fungicide, PW40 anti-fungal agent, thickener TT935, required coloring agent and the remaining part of deionized water until uniform to form a water-based paint combination. The usage amount of each component in the water-based coating composition of Examples 1-2 and the properties of the water-based coating composition and the coating fo...

Abstract

The invention relates to wall base cloth and a manufacturing method thereof. The wall base cloth comprises a supporting base material and an outer water dispersibility polyurethane base layer, wherein the supporting base material comprises a polymer material layer containing one or more kinds of plasticizers, and the polymer material layer is arranged on the main surface of the supporting base material; and the outer water dispersibility polyurethane base layer is formed on the polymer material layer, so that the free surface of the wall base cloth is formed. The free surface of the wall base cloth basically does not contain the plasticizers.

Description

technical field [0001] The invention relates to a laminated product, in particular to a wall base cloth covering a wall and a manufacturing method thereof. The invention also relates to a method for enclosing a polymeric material comprising one or more plasticizers, in particular to a method for preventing migration of plasticizers in the polymeric material therefrom. Background technique [0002] The wall base cloth is regarded as "the companion of the paint composition for the wall", and it is a new type of wall decoration material that integrates the dual effects of paint and wallpaper. This wall decoration material, when used in conjunction with a paint composition, can greatly improve the expressiveness of the paint composition, bring more texture and shape to the wall, and overcome the shortcomings of lack of texture and monotony in traditional paint compositions. Also, it can be recoated with the coating composition. [0003] Typically, wall base fabrics are in the ...
