Problems solved by technology

[0007]The current paper pulp internal sizing agents mainly include rosin glue, reinforced rosin glue, dispersed rosin glue, petroleum resin glue, paraffin glue, etc. Among them, rosin sizing agent And petroleum resin sizing agents are mainly used in acidic papermaking, and the effect on filler modification is poor, so it is difficult to meet the requirements of industrial production

Embodiment 1

[0028] A kind of paper made of stearic acid modified nano-titanium dioxide is prepared according to the following steps:

[0029] (1) First make aluminum sulfate into an aqueous solution with a mass concentration of 5%, impregnate the filter paper for 1 min, and place the filter paper at 100 o C under drying number;

[0030] (2) Put stearic acid with a concentration of 5% in ethanol, add nano-titanium dioxide in the ratio of nano-titanium dioxide: stearic acid = 1:1, and disperse it in stearic acid-ethanol solution to obtain stearic acid containing nano-titanium dioxide - ethanol solution, pulling and dipping the filter paper impregnated with aluminum sulfate mentioned in step (1) in the ethanol solution of stearic acid-nano-titanium dioxide for several times; after that, air-drying for 24 hours to obtain.

Embodiment 2

[0032] A kind of paper made of stearic acid modified nano-titanium dioxide is prepared according to the following steps:

[0033] (1) First make aluminum sulfate into an aqueous solution with a mass concentration of 20%, impregnate the filter paper for 3 minutes, and place the filter paper at 105 o Drying number at C; (2) Put 9% stearic acid in ethanol, add nano-titanium dioxide in the ratio of nano-titanium dioxide: stearic acid = 1:4, disperse in stearic acid-ethanol solution, and oscillate for 8 minutes Obtain the stearic acid-ethanol solution containing nano-titanium dioxide, and coat the prepared stearic acid-ethanol solution on the surface of the filter paper with a paint scraper, and the coating amount should be controlled to be 8g / m 2 ; Afterwards, the impregnated filter paper was dried at 105° C. for 15 minutes in a constant-temperature blast drying oven to obtain a final product.

Abstract

The present invention relates to paper made through stearic acid modified nanometer titanium dioxide. The preparation method comprises: (1) preparing an aluminum sulfate aqueous solution with a concentration of 5-20%, dipping filtration paper in the solution for 1-3 min, drying the filtration paper at a temperature of 100-105 DEG C, and numbering; and (2) adding stearic acid with a concentration of 5-9% to ethanol, adding nanometer titanium dioxide according to a ratio of the nanometer titanium dioxide to the stearic acid of 1:1-1:4, dispersing into the stearic acid-ethanol solution to obtain the stearic acid-ethanol solution containing the nanometer titanium dioxide, carrying out pulling dipping on the filtration paper obtained in the step (1) in the stearic acid-nanometer titanium dioxide ethanol solution a plurality of times, and carrying out air drying for 24-48 h so as to obtain the product.

Description

technical field [0001] The invention relates to a paper made with filling, in particular to a paper made of stearic acid modified nano-titanium dioxide and a preparation method thereof. Background technique [0002] Stearic acid, English name: Stearic Acid Alias: octadecanoic acid, octadecanoic acid, fatty wax acid, is a kind of high-grade saturated fatty acid, pure product is white soft flakes with luster. Relative density 0.9408 (20°C), melting point 69~70°C, boiling point 383°C, refractive index 1.4299 (80°C), industrial product is white or yellowish granular, a mixture of stearic acid and palmitic acid, and contains a small amount of oil Sour, slightly buttery smell. Slightly soluble in cold water, easily soluble in benzene, toluene, chloroform, carbon tetrachloride, carbon disulfide, amyl acetate, etc., also soluble in ethanol and acetone. Stearic acid itself has a lubricating effect and is often used as a hydrophobic agent. When the paper is modified, it can endow th...
