Embodiment 1

[0045] This embodiment is a flame retardant, and the preparation process of the flame retardant is as follows:

[0046] A1: Add the catalyst and half of glacial acetic acid into a three-necked flask equipped with an air duct and a stirrer, stir at a stirring rate of 150r / min until the catalyst is completely dissolved, then add toluene and continue stirring for 20min, then add the remaining Glacial acetic acid, heated to 95°C, fed with oxygen, heated to reflux for 10 hours, after the reaction, the reaction product was extracted twice with cyclohexane, the extracts were combined, and the cyclohexane was distilled off under reduced pressure to obtain intermediate 1; The control catalyst is cobalt acetate, manganese sulfate, manganese acetate and tetrabromoethane according to the molar ratio of 6:1:1:0.36, the molar ratio of cobalt acetate to toluene is 1:30, and the volume ratio of toluene to glacial acetic acid is 1: 1. The oxygen flow rate is 60mL / min;

[0047] A2: Add p-pheny...

Embodiment 2

[0051] This embodiment is a flame retardant, and the preparation process of the flame retardant is as follows:

[0052] A1: Add the catalyst and half of glacial acetic acid into a three-necked flask equipped with an air duct and a stirrer, stir at a stirring rate of 300r / min until the catalyst is completely dissolved, then add toluene and continue stirring for 30min, then add the remaining Glacial acetic acid, under the condition of raising the temperature to 100°C, feed oxygen, heat and reflux for 12 hours, after the reaction, extract the reaction product with cyclohexane for 3 times, combine the extracts, and distill under reduced pressure to remove the cyclohexane to obtain intermediate 1; The control catalyst is cobalt acetate, manganese sulfate, manganese acetate and tetrabromoethane according to the molar ratio of 6:1:1:0.36, the molar ratio of cobalt acetate to toluene is 1:35, and the volume ratio of toluene to glacial acetic acid is 1: 1. The oxygen flow rate is 60mL / ...

Embodiment 3

[0057] This embodiment is a kind of aldehyde-removing powder, and the preparation process of aldehyde-removing powder is as follows:

[0058] B1: Add halloysite to the urea solution, sonicate for 1 h at an ultrasonic frequency of 45 kHz, then centrifuge and remove the supernatant, wash the precipitate twice with isopropanol, and then vacuum filter it. The filter cake is placed in a vacuum drying oven, dried to constant weight at a temperature of 70°C, and then ground into powder and passed through a 300-mesh sieve to obtain the carrier halloysite; the dosage ratio of halloysite and urea solution is controlled to be 2g : 50mL, the molar concentration of urea solution is 1mol / mL;

[0059] B2: Add the carrier halloysite into the reaction eggplant bottle, and treat it under negative pressure for 30 minutes under the condition of vacuum degree of -0.1MPa, then inject the 2-imidazolidinone aqueous solution into the reaction eggplant bottle through a syringe, shake for 30 minutes, an...

Abstract

The invention discloses a formaldehyde-removing coating containing anion powder and a preparation method thereof, and relates to the field of paints.The preparation method comprises the following steps: a flame retardant, formaldehyde removal powder and waterborne resin powder are evenly mixed to obtain a mixture, and the mixture is subjected to melt extrusion, granulation and smashing to obtain nano inorganic formaldehyde-removing resin; and the nano inorganic formaldehyde-removing resin and other raw materials are uniformly stirred to obtain the formaldehyde-removing coating. The flame retardant and the formaldehyde removal powder are added into water-based resin, the flame retardant endows the water-based resin with excellent flame retardance, the formaldehyde removal powder endows the water-based resin with excellent formaldehyde removal performance, and after the water-based resin and water are fused to form the coating, the coating has flame retardance and formaldehyde removal performance; meanwhile negative ion powder is added, and the negative ion powder can destroy the activity of cell membranes of bacteria or cell protoplast active enzymes, so that the antibacterial and bactericidal purposes are achieved, indoor peculiar smells and various harmful gases can be eliminated, and the effects of purifying indoor air and improving the indoor air quality are achieved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an aldehyde-removing coating containing anion powder and a preparation method thereof. Background technique [0002] In recent years, with the development of my country's economy and the improvement of people's living standards, people's awareness of environmental protection and health requirements are increasing day by day, and the pollution caused by toxic and harmful substances in building decoration materials to the environment and the impact on human health have become increasingly prominent; [0003] Toxic and harmful substances mainly come from formaldehyde pollutants released by building decoration materials, mainly from plywood, joinery boards, paints and coatings and other decorative materials used for interior decoration. It is a colorless and soluble irritating gas. It is relatively harmful to the human body. It can cause irritation to the eyes, skin, and respiratory tract, an...
