Example Embodiment

[0053] Example 1 Preparation of thermoplastic polyurethane foamed resin adhesive

[0054] Wet foamed PU resin 100kg

[0055] Hot melt adhesive 50kg

[0056] Release agent 4kg

[0057] MEK 30kg

[0058] Stir the above materials with a mixer for 5-10 minutes to mix evenly, and then use a 10,000-horsepower machine to heat at 80° C. for 5-8 minutes to press and age the material to obtain a thermoplastic polyurethane foamed resin viscose.

Example Embodiment

[0059] Example 2 Preparation of plastic sheet

[0060] The thermoplastic polyurethane foamed resin adhesive prepared in Example 1 was uniformly coated on the back of the plastic base plate by a coating and scraping device, and the thickness was controlled at about 0.4 mm. Then it is flattened by a four-roller calender, so that the resin adhesive can fully penetrate into the back of the sheet. Then, the temperature of the dryer is used to dry the material at about 135° C., and the cooling fan is used to cool to room temperature to obtain the building board according to the present invention.

Example Embodiment

[0061] Example 3 Use of Plastic Sheets

[0062] 1. Ensure that the ground is clean, dry and level;

[0063] 2. Use a hot blower or an oven to heat the part of the plastic sheet prepared in Example 2 that is coated with thermoplastic polyurethane foam resin adhesive. need to be laid on the ground;

[0064] 3. Use stainless steel push rollers to flatten the ground;

[0065] 4. Natural cooling and flattening.

[0066] Detection of the adhesion between the board and the ground:

[0067] At the midpoint of any side of the above-mentioned laid plastic sheet with an area of ​​1 square meter, use a digital display spring tension gauge to detect the adhesion of the plastic sheet to the ground. The results show that the adhesion between the board and the ground is 3-5kg / m 2 .

Abstract

The invention belongs to the field of building materials, and in particular relates to thermoplastic polyurethane foaming resin mucilage glue as well as a preparation method and use thereof, and a product containing the thermoplastic polyurethane foaming resin mucilage glue. The thermoplastic polyurethane foaming resin mucilage glue mainly comprises wet foaming polyurethane (PU) resin, hot melt glue, a mold release and an unnecessary solvent. The thermoplastic polyurethane foaming resin mucilage glue can be coated to substrates of panels such as various plastic ground materials and wall space materials. In the construction process of gluing panels containing the thermoplastic polyurethane foaming resin mucilage glue, various splicing materials such as glue and paste are not additionally used. The substrate roasted can be directly glued to grounds and wall spaces or other necessary places.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a thermoplastic polyurethane (TPU) foaming resin adhesive, its preparation method, application and products containing the thermoplastic polyurethane foaming resin adhesive. The thermoplastic polyurethane foaming resin adhesive mainly includes wet foaming polyurethane (PU) resin, hot melt adhesive, release agent and optional solvent. The thermoplastic polyurethane foaming resin adhesive can be coated on the substrates of various plastic floor materials and wall materials, etc., and it is not necessary to use additional materials during the construction process of pasting the boards including the thermoplastic polyurethane foaming resin adhesive. Adhesive materials such as glue and paste can be directly pasted on the ground, wall or other required places after heating the substrate. Background technique [0002] Recently, with the development of social economy and th...
