Abstract

The invention discloses a cationic paper-making composite retention aid, as well as a preparation method and an application method thereof. The cationic paper-making composite retention aid is formed by mixing the following components in parts by weight: 5-15 parts of bentonite, 20-35 parts of calcite, 10-20 parts of aedelforsite, 10-20 parts of sepiolite, 5-10 parts of attapulgite, 5-15 parts of zeolite, 5-10 parts of hydrotalcite and 5-10 parts of kaolin, and the total parts are of 100 parts. The retention aid disclosed by the invention comprises the hydrotalcite and a variety of non-metallic mineral powder, and potential energy matching is performed on an anti-agglomeration mechanism and a dispersion law of the variety of the non-metallic mineral powder by utilizing the chemical modifiable character of a hydrotalcite layer plate, the regulatability of the type and the number of inter-layer ions, the regulatability of size and distribution of crystals and the characteristics that the layer plate contains hydrocarbyl and has a memory effect, so that the product quality is improved, the production cost is reduced and the green and environment-friendly production is realized during the paper-making process.

Description

technical field [0001] The invention relates to a cationic composite retention aid for papermaking, a preparation method and an application method thereof. Background technique [0002] As we all know, bentonite retention aid has the function of retaining fillers and fine fibers. It is one of the essential raw materials in the paper industry. It can reduce the loss of fine fibers in pulp, reduce raw material consumption, and improve paper quality. Therefore, it is widely used in in the paper industry. However, the retention rate of bentonite retention aid is low (about 60%-65%), and the burden of white water is heavy. In the process of acidic, neutral and alkaline papermaking, affected by the steric hindrance and steric hindrance, the paper fibers and mineral fibers will be agglomerated, so it cannot improve product quality, reduce product cost and protect the environment in the papermaking industry. purpose of production. Contents of the invention [0003] The purpose ...
