Problems solved by technology

At present, the installation of plastic panels (such as floor and wall panels) on the market requires the use of glue construction. The process is cumbersome and inconvenient, and the waste of glue raw materials increases costs, consumes manpower, is inconvenient to construct, and is easy to fall off or cause deformation and warping after a short period of use abnormal

Effect test

Embodiment 1

[0053] The preparation of embodiment 1 thermoplastic polyurethane foaming resin viscose

[0054] Wet foaming 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 to 10 minutes to mix them evenly, and then heat them at 80°C for 5 to 8 minutes with a 10,000-horsepower machine to carry out pressing and curing to obtain thermoplastic polyurethane foaming resin glue.

Embodiment 2

[0059] The preparation of embodiment 2 plastic sheets

[0060] Apply the thermoplastic polyurethane foaming resin adhesive prepared in Example 1 evenly on the back of the plastic base plate through the coating and scraping equipment, and control the thickness to about 0.4mm. Then it is flattened by a four-roller calender, so that the resin glue can fully penetrate into the back of the board. Then use a dryer to dry the material at a temperature of about 135° C., and use a cooling fan to cool to room temperature to obtain a building board according to the present invention.

Embodiment 3

[0061] The use of embodiment 3 plastic sheets

[0062] 1. Make sure the ground is clean, dry and flat;

[0063] 2. Use a hot air blower or an oven to heat the part of the plastic sheet prepared in Example 2 that is coated with thermoplastic polyurethane foaming resin glue. The temperature is about 60°C-80°C. 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 plate 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 between the plastic sheet and 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...
