Description
Technical Field
The invention relates to the technical field of coatings, in particular to an environment-friendly antibacterial interior wall coating and a preparation method thereof.
Background
Indoor pollution caused by the conventional decorative materials which are widely used at present draws more and more high attention of people, and in recent years, common environment-friendly coatings appear on the market, wherein the coatings do not pollute the environment, do not release harmful substances to human bodies, but have poor texture, do not have a lasting purification effect on indoor air, and cannot meet the requirements on the decoration effect and the air quality.
Disclosure of Invention
The invention aims to provide an environment-friendly antibacterial interior wall coating and a preparation method thereof, and the environment-friendly antibacterial interior wall coating has the advantages of good construction performance, high curing speed, good adhesive force, wear resistance, pollution resistance, low volatility, environmental friendliness and no pollution, and can effectively purify air and improve the indoor environment.
The invention provides the following technical scheme: an environment-friendly antibacterial interior wall coating comprises the following raw materials in parts by weight: 58-60 parts of rosin resin, 52-55 parts of acrylic emulsion, 35-36 parts of shell powder, 29-31 parts of natural antibacterial agent, 26-28 parts of inorganic antibacterial agent, 23-25 parts of crop starch, 20-22 parts of alkaloid, 18-19 parts of vegetable gum, 16-18 parts of pigment, 10-13 parts of auxiliary agent and 60-63 parts of water;
the natural antibacterial agent comprises the following raw materials in parts by weight: 15-16 parts of modified bamboo pulp fiber, 10-12 parts of ginkgo leaf extract, 8-9 parts of pomegranate bark extract and 5-6 parts of coconut oil essence;
the inorganic antibacterial agent comprises the following raw materials in parts by weight: 13-16 parts of nano zinc oxide, 10-12 parts of nano titanium dioxide and 5-10 parts of nano silicon dioxide;
the auxiliary agent comprises the following raw materials in parts by weight: 2-3 parts of a film forming additive, 2-3 parts of an antifreezing agent, 1-2 parts of a curing agent, 1-2 parts of a dispersing agent, 0.8-1.2 parts of a defoaming agent and 0.6-0.8 part of a water-retaining agent.
The modified bamboo pulp fiber comprises the following raw materials in parts by weight: 5-8 parts of bamboo pulp fiber, 1-2 parts of chitosan, 1-2 parts of sericin, 0.8-1.2 parts of hydrogen peroxide solution and 0.6-0.8 part of sodium periodate solution.
The preparation method of the modified bamboo pulp fiber comprises the following steps: weighing bamboo pulp fibers, adding the bamboo pulp fibers into a sodium periodate solution, stirring at a rotating speed of 200-300 r/min for 10-20 min, adding an acid solution, adjusting to be neutral, sequentially adding chitosan, sericin and a hydrogen peroxide solution, carrying out ultrasonic treatment for 1-2 h, filtering to obtain filter residues, putting the filter residues into an oven, and drying to obtain the bamboo pulp fibers.
