Description

Technical Field

[0001] The present invention relates to the technical field of floor paints, and specifically to a low-odor and low-amine-odor environmental protection floor paint and a preparation method thereof. Background Art

[0002] At present, the environmentally friendly floor paints on the market are mainly water-based and oil-based, and there are problems such as strong odor and unpleasant smell. Water-based floor paints can be used in homes, and mainly have problems of being not wear-resistant, not stain-resistant, and having limited color varieties. In environmentally friendly solvent-free floor paints, due to the use of amine curing agents, there is a strong amine odor, and they generally contain harmful substances such as nonylphenol. Nonylphenol contains toxic components and is widely used in the printing and dyeing and cleaning processes in the textile industry. In addition to the textile industry, nonylphenol can also be used as a surfactant and a cleaning agent. It has an endocrine disrupting effect, can promote the proliferation of breast cancer cells, belongs to endocrine disruptors and carcinogens. In addition, during actual use, epoxy floor paints are often rubbed by external objects and are prone to film wear. AgE epoxy active diluent has reproductive toxicity and is prohibited by the European Union. Summary of the Invention

[0003] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides a low-odor and low-amine-odor environmental protection floor paint and a preparation method thereof, which have the functions of odor purification and deodorization, and have a good decomposition and removal effect on malodors such as amine odor.

[0004] The technical solution provided by the present invention: A low-odor and low-amine-odor environmental protection floor paint, including component A and component B. By weight percentage, component A includes: 32-40% of 128 epoxy resin, 7-20% of 692 epoxy active diluent benzyl glycidyl ether, 6-10% of benzyl alcohol, 10-20% of inorganic color paste, 20-40% of porous ore powder, and component B includes: 46-60% of trimethylcyclohexylamine, 10-25% of nonylphenol substitute, 10-20% of benzyl alcohol, 6-10% of K54 epoxy accelerator, and 1-2% of natural plant essence.

[0005] Further, the mass ratio of component A to component B is 4-5:1.

[0006] Further, the porous ore powder is any one of fine zeolite powder, attapulgite powder, and coal ash.

[0007] Further, the nonylphenol substitute is any one of petroleum resin and dodecylphenol.

[0008] Further, the natural plant essence is any one of citral, heliotropin, vanillin, and ethyl vanillin.

[0009] Another technical solution provided by the present invention: A preparation method of a low-odor and low-amine-odor environmental protection floor paint, including the following steps:

[0010] (1) Pour 128 epoxy resin, 692 epoxy active diluent benzyl glycidyl ether, and benzyl alcohol into a stirring tank in sequence and stir. Then add inorganic color paste and porous ore powder, stir and mix, and then filter and package to obtain Component A.

[0011] (2) Put trimethylcyclohexylamine, nonylphenol substitute, and benzyl alcohol into a reaction kettle in sequence, start stirring and react for 2 hours. After the temperature cools below 50 degrees, add K54 epoxy accelerator and natural plant essence, stir evenly and discharge to obtain Component B.

[0012] (3) During construction, mix Component A and Component B in proportion and cure to obtain an environmentally friendly floor paint.

[0013] Further, in step (1), after adding 128 epoxy resin, 692 epoxy active diluent benzyl glycidyl ether, and benzyl alcohol, stir at 1000 revolutions per minute for 20 minutes, then add inorganic color paste and porous ore powder and continue to stir for 20 minutes.

[0014] The beneficial effects of the present invention are as follows: (1) Epoxy resin reacts with trimethylcyclohexylamine to form a network cross-linked macromolecular structure and form a film. One of petroleum resin and dodecylphenol is used to replace nonylphenol, and petroleum resin or dodecylphenol is introduced into the epoxy resin system in a chemically modified manner to form a homogeneous and stable modified epoxy resin composite material. This composite material has excellent toughness and adhesion to various substrates;

[0015] (2) Natural plant extract essence, aldehyde essence, etc. react to remove amine odor, having a deodorizing effect, having a good decomposition and removal effect on malodors such as amine odor, and strongly adsorbent porous ore powder adsorbs amine odor, having a smell purification effect and being more environmentally friendly;

[0016] (3) The present invention improves the disadvantages of poor acid resistance, brittle and easy to crack, and poor weather resistance of the epoxy resin coating film. It has the characteristics of high mechanical strength, excellent corrosion resistance, high adhesion, and good wear resistance of epoxy resin;

[0017] (4) 692 epoxy active diluent benzyl glycidyl ether replaces the toxic AgE epoxy active diluent, making the floor paint of this application safer and more environmentally friendly. Specific Embodiments
