Abstract

The invention belongs to the technical field of fine chemicals for papermaking, and particularly relates to a modified guar gum thickener for papermaking paints and a preparation method thereof. The thickener is prepared from the following raw materials in percentage by weight: 0.4-20% of guar gum, 2-20% of unsaturated acid, 5-40% of acrylate, 0.1-3% of functional monomer, 0.02-5% of emulsifier, 0.01-2% of crosslinking agent, 0.2-3% of initiator, 0.3-1% of pH buffering agent and the balance of water. The chemically modified guar gum has stabler structure, and overcomes the defect of high tendency to generate flocculation and microbes. The original dissolution by heating and stirring is changed into direct addition, thereby greatly lowering the heat energy, saving abundant time for preparing the papermaking paint, endowing the guar gum with favorable flowability, solving the problem of high splash tendency in the overcoating process of the papermaking paint, reducing the consumption of the adhesive, adhesion promoter and OBA (optical bleaching agent), and lowering the production cost.

Description

technical field

[0001] The invention belongs to the technical field of fine chemicals for papermaking, and in particular relates to a modified guar gum thickener for papermaking coatings and a preparation method thereof. Background technique

[0002] The paper-making coating thickeners that appear on the market are all water-soluble natural polymer materials, which can make the coating have a certain viscosity and suspension force, but the steps are often cumbersome and time-consuming when adding, and they have no fluidity and poor transparency. , Splashing and flocculation are prone to occur during the construction process, and microorganisms that are harmful to paper quality are easy to breed.

[0003] Guar gum is a highly purified natural polysaccharide extracted from guar beans. Due to its unique molecular structure and naturalness, it has quickly become a new environmentally friendly papermaking additive with superior performance. Guar gum can be dispersed in water to ...
