Embodiment 1

[0016] An attapulgite-grade paper-making auxiliary agent is characterized in that it is made up of the following raw materials in parts by weight:

[0017] Attapulgite 70, aluminum trifluoride 3, sepiolite powder 10-20, bentonite 30, polyoxyethylene glyceryl ether 2, calendula soaking oil 0.3-1, sodium borohydride 2, hydroxyethylidene diphosphonic acid 3, Silver nitrate 0.5, dibromohydantoin 0.5, cetyltrimethylammonium chloride 2, ammonium metavanadate 0.4, casein 2, calcium lignosulfonate 3, polyethylene glycol 1000 2.

[0018] A preparation method of attapulgite-grade papermaking auxiliary agent is characterized in that it comprises the following steps:

[0019] (1) Attapulgite and bentonite were naturally weathered on the site for 60 days, soaked in a 7% sodium hydroxide solution for 12 hours, taken out, washed 4 times, dried, and ground to obtain the base material;

[0020] (2) Add sodium borohydride to 6 times the water, stir evenly, add ammonium metavanadate, stir evenl...

Abstract

The invention discloses an attapulgite-level paper-making additive. The attapulgite-level paper-making additive comprises the following materials in parts by weight: 60-70 parts of attapulgite, 2-3 parts of aluminum fluoride, 10-20 parts of sea-foam stone powder, 20-30 parts of bentonite, 2-3 parts of polyoxyethylene glyceryl ether, 0.3-1 part of calendula soaking oil, 1-2 parts of sodium borohydride, 3-4 parts of hydroxy ethylidene diphosphate, 0.3-0.5 part of silver nitrate, 0.5-2 parts of dibromo-5,5-dimethylhydantoin, 1-2 parts of cetyltrimethylammonium chloride, 0.4-1 part of ammonium metavanadate, 1-2 parts of casein, 3-4 parts of calcium lignosulphonate and 2-3 parts of polyethylene glycol 1000. The attapulgite-level paper-making additive can be uniformly distributed in paper pulp, so that the favorableness to bonding among paper-pulp materials is achieved, the used amount of the materials of the paper pulp is reduced, the fiber structure of the paper pulp is improved, the ring crush compression resistance, the glossiness, the softness, the whiteness and the flatness of the paper are improved, and the linting and the fluffing of the paper in the use process are avoided, the quality of the paper is improved, and the decontaminating and environment-friendly effects are achieved.

Description

technical field [0001] The invention mainly relates to the field of papermaking, in particular to an attapulgite grade papermaking auxiliary agent. Background technique [0002] At present, a large amount of wood and plant materials are used in the pulp of my country's paper industry, which seriously damages the environment of ecological resources, and the high cost cannot play a decontamination and environmental protection role in the paper industry. Attapulgite additives are a kind of mixed crystal mineral fiber additives jointly developed with natural attapulgite nano-scale porous fibers, silicate clay minerals and rare long-fiber minerals. The color is white, off-white or off-white. Delicate, smooth surface, light texture, after special processing, it has good viscosity and thixotropy, its crystals are arranged in fiber mesh, its adsorption performance and suspension performance are higher than other mineral additives. Contents of the invention [0003] The ob...
