Carbon-black-based water-based paint as well as preparation method and application thereof

Abstract

The invention relates to carbon-black-based water-based paint as well as a preparation method and application thereof. The carbon-black-based water-based paint uses carbon black, kaolin and calcium carbonate as pigments to be subjected to high-speed shearing dispersion for a certain time together with sodium hexametaphosphate dispersing agent solution and polyether type defoaming agents so as to prepare pigment water phase dispersion liquid; then, ingredients such as carboxymethyl cellulose, adhesive modification starch and antibacterial agent modification chitosan are added according to the specific programs; the carbon-black-based water-based paint is obtained through high-speed shearing dispersion. The carbon-black-based water-based paint is mainly applied to surface coating of fruit bearing bag outer bag paper; the process is simple; the production cost is low; the utilization rate of carbon black is improved; the cleanness and the environment protection of production workshops are facilitated.

Description

technical field [0001] The invention relates to the technical field of carbon black pigment and fruit-growing bag paper, in particular to a carbon black-based water-based coating and a preparation method thereof, which is mainly used for surface coating of fruit-growing bag paper. Background technique [0002] Carbon black is a kind of amorphous carbon, which is a product obtained by incomplete combustion or thermal decomposition of carbon-containing substances under the condition of insufficient air. Carbon black has excellent colorability, weather resistance and chemical stability, and is an indispensable ideal black pigment in the coatings industry. [0003] The carbon black paint involved in the present invention is mainly applied to the surface coating of fruit bag paper. Fruit bag paper is a kind of special paper used for fruit bagging during the growth period of fruit trees. It is a high-tech and high value-added agricultural technical paper for bagging and protectin...

Problems solved by technology

At present, the Yuguo bag paper factory basically adopts the lamination method to produce the outer bag paper. The inner surface is black because the carbon black is dyed in the pulp. This not only complicates the production equipment, but also increases the production cost. Moreover, the loss of carbon black is serious and the environment is polluted. protrude
