Environmental protection type building coating material additive

Abstract

The present invention discloses an environmental protection type building coating material additive, which comprises, by weight, 100 parts of zeolite crystal ore micro-powder, 1-3 parts of nanometer calcium powder, 2.5-4 parts of an antiseptic bactericide, 2-5 parts of catalyst micro-powder, 2-5 parts of an anti-foaming agent, 2-3 parts of fluorescent whitening powder, and 100-300 parts of water. The preparation steps comprise that: zeolite crystal ore is added to a crusher so as to be crushed, enters a pair-roll mill so as to be grinded into fine sand, and enters a high speed vortex mill so as to be crushed, the obtained powder enters a gas flow classifier and is subjected to cyclone separation to obtain powder with the main particle size of 1250 mesh, 1-3 parts by weight of nanometer calcium powder, 2.5-4 parts by weight of an antiseptic bactericide, 2-5 parts by weight of catalyst micro-powder, 2-5 parts by weight of an anti-foaming agent, 2-3 parts by weight of fluorescent whitening powder, and 100-300 parts by weight of water are added, strengthened stirring is performed, and the obtained material enters an efficient wet grinding machine to carry out secondary grinding to obtain the additive product. Compared with the environmental protection type building coating material additive in the prior art, the product of the present invention has characteristics of fine particle size, high concentration of the released negative ions, effective elimination of indoor odor, inhibition of harmful bacteria breeding, and sustained release of negative ions.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an environment-friendly architectural paint additive. Background technique [0002] At present, the coating additives used in the production of architectural coatings are generally based on negative ion gemstones, and the particle size distribution of the powder is quite wide. Once such additives are included in water-based coatings, coarse particles often appear on the wall, affecting The surface quality of the wall after decoration and the negative ion release rate also have a certain degree of influence. Contents of the invention [0003] The object of the present invention is to provide a kind of environment-friendly architectural coating additive with smaller particle size, more uniform, better negative ion release and better whiteness in order to overcome the defects in the above-mentioned prior art. [0004] The purpose of the present invention can be achieved...
