With the passing of time and the development of science, our knowledge of polymer flooring maintenance materials has also been fundamentally changed. More and more users begin to pay attention to the function and useful concept of products. The new flooring no longer excessively seeks the needs of light, smoothness and endless hardness of polymer flooring, but also needs the appearance of light, soft and hard without cracking Pay attention to meet the functional needs of the owners.

The flooring materials with this function are very sophisticated. Many of the main materials with high resin content and solvent-free are used first, together with a transparent, colorless, low viscosity, non volatile gas curing agent. In addition, the flexible function of the curing agent is needed to slow down the strong internal stress of the main materials with high solid content, defeat the glass flower crack caused by the brittleness, and make the flooring fully reflect the purity The high-density waterproof and anti-corrosion properties of epoxy resin ensure moderate softness and hardness, and prevent cracking and scratch. Because of the new floor plan concept and the owner's demand for functions, polyether amine, alicyclic amine, or its modified alicyclic amine, alicyclic amine modified polyether amine are generally used in the international epoxy floor, but its selection proportion is increasing.

1. Painting process of amino terminated polyether foaming agent: the surface of the coated material shall undergo a series of processes such as pretreatment, painting, gluing, curing, etc. The bonding surface of the anti-theft door can be cleaned with detergent, so that the cleaned surface will not appear corrosion and oil stains.

2. In order to make the styrofoam hair have a strong bonding strength, before use, firstly apply the adhesive processed by amino polyether on the surface of the adhesive evenly. It is recommended to use toothed plastic blade rather than brush. Before use, we can determine the amount of glue according to the embossing depth of the door panel. In the process of use, apply the glue on the adhesive On the surface, remember that the coating should not be too thick, and the exposure time should not be too long.

3. In the process of gluing, we pay attention to the speed. In the hot summer, the speed should be faster, and we can't brush back and forth for many times. If the action is too slow in the process of brushing, we can put the gluing edge on the gluing machine for pressure test, and don't wait until the surface of gluing is dry. In the process of gluing, we can use cold pier or hot upsetting. The best time for cold pier is 3-4 hours, while the best time for hot pier is 15-30 minutes.

4. After all processes are completed, if there is any glue that is not used up, we should cover the cover of amino polyether adhesive at this time, so as to avoid the phenomenon of curing and crusting if there is a gap left.

5. The amino terminated polyether styrofoam must be placed in a dry, ventilated and sealed environment, without water.
