Abstract

The invention relates to the field of coating production, in particular to a waterproof coating capable of absorbing formaldehyde, which is prepared from the following raw materials in parts by weight: 60-70 parts of organic silicon resin, 6-10 parts of graphene, 3-5 parts of montmorillonite, 3-5 parts of calcium carbonate, 10-15 parts of diatomite, 1-2 parts of a thickener, 2-4 parts of nano silver oxide and the balance of water. A preparation method of the waterproof coating comprises the following processes: mixing montmorillonite, calcium carbonate, graphene, diatomite and nano silver oxide, and milling the components for 5-8 minutes at a speed of 2000-2500 rpm to obtain a premix; 2, adding organic silicon resin and a thickening agent in the raw materials into the premix prepared in the step 1, and milling the components for 5-8 minutes at the speed of 2,000 to 2,500 rpm to obtain a mixture; and 3, adding water into the mixture, stirring the mixture, and uniformly mixing all the components to obtain the waterproof coating. The waterproof coating has the functions of water resistance, sterilization, corrosion resistance and formaldehyde absorption.

Description

technical field [0001] The invention relates to the technical field of coating production, in particular to a waterproof and formaldehyde-absorbing coating and a preparation method thereof. Background technique [0002] Paint is coated on the surface of the object to be protected or decorated, and forms a continuous film firmly attached to the object to be coated, usually based on resin, oil or emulsion, and its raw materials need to be ground into sufficiently fine powder before processing and configuration shape, and then mixed and fully stirred, and then made into a liquid with organic solvents or water. Traditional coatings do not have the functions of sterilization, anticorrosion and absorption of formaldehyde, and their waterproof performance is relatively poor, so they cannot automatically adjust the water balance. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a waterproof and formaldehyde-absorbing coa...
