Abstract

The invention relates to a modified attapulgite paper filler. The modified attapulgite paper filler is prepared from the following raw materials in parts by weight: 3-5 parts of nanometer bentonite, 0.8-1.2 parts of sodium carbonate, 3-4 parts of styrene-butadiene emulsion, 3-5 parts of Camphora officinarum bark, 1-1.5 parts of dry alkyd resin, 1-1.3 parts of melamino-formaldehyde resin, 2-3 parts of electric mountain powder, 1-1.6 parts of microcrystalline cellulose, 0.4-0.6 part of sodium laurate, 2-3 parts of colloidal silicon dioxide, 1-2 parts of carbomer, 0.5-0.8 part of ceteth-n sterate, 100-120 parts of attapulgite, a proper amount of water, 5-10 parts of assistants, and 20-25 parts of a 2-3% hydrochloric acid solution. The attapulgite modification method can well remove impurities in the attapulgite, so as to improve the activity, the dispersibility and the suspension property of the attapulgite, improve the using effect of the attapulgite in papermaking and enable paper to be soft and difficult to fracture; and the Camphora officinarum bark is added to improve the mothproof performance of the paper.

Description

technical field [0001] The invention belongs to the field of attapulgite processing, in particular to a modified attapulgite paper filler and a preparation method thereof. Background technique [0002] Attapulgite has good colloidal properties such as unique dispersion, high temperature resistance, salt and alkali resistance, and high adsorption and decolorization ability. It also has certain plasticity and cohesive force, strong water absorption, stickiness and plasticity when wet, small shrinkage after drying, no obvious cracks, soaking in water and disintegration, and suspension does not flocculate and precipitate when it encounters dielectrics. Therefore, attapulgite is widely used in many fields such as sewage treatment, adsorption purification, detergent, rubber, paint, papermaking, light industry, agriculture, cosmetics, etc. It is an important non-metallic mineral. [0003] In order to further improve the use effect of attapulgite and enhance its overall physical an...
