Paper prepared through carboxymethylcellulose modified sodium silicate pulp and preparation method thereof

Abstract

The invention provides paper prepared through carboxymethylcellulose modified sodium silicate pulp. The paper is prepared through the following steps: firstly, preparing water solution of aluminum sulfate with the mass concentration percent of 5-20%, dipping filter paper for 1-3 min, then drying and numbering the filter paper at 100-105 DEG C, secondly, adding sodium silicate into carboxymethylcellulose ethyl alcohol with carboxymethylcellulose concentration of 8-12% according to the ratio of sodium silicate to carboxymethylcellulose being 1:1 to 1:4, so as to ensure that the sodium silicate is dispersed in carboxymethylcellulose-ethyl alcohol solution, obtaining carboxymethylcellulose-ethyl alcohol solution containing sodium silicate, lifting and dipping the filter paper dipped by aluminum sulfate and obtained in step one into the carboxymethylcellulose-sodium silicate ethyl alcohol solution for multiple times, and then performing air drying on the filter paper for 24-48 h, so as to obtain the paper.

Description

[0001] technical field

[0002] The invention relates to paper made with filling, in particular to paper made with carboxymethyl cellulose modified sodium silicate and a preparation method thereof. Background technique

[0003] Carboxymethyl cellulose is a carboxymethyl group substitution product of cellulose. According to its molecular weight or degree of substitution, it can be a completely soluble or insoluble polymer. The latter can be used as a weak acid cation exchanger to separate neutral or basic proteins. Carboxymethyl cellulose can form high-viscosity colloids and solutions, have the characteristics of adhesion, thickening, flow, emulsification and dispersion, shaping, water retention, protective colloid, film forming, acid resistance, salt resistance, suspension, etc., and is physiologically harmless Therefore, it is widely used in the production of food, medicine, daily chemical, petroleum, paper making, textile, construction and other fields.

Embodiment 1

[0030] A kind of paper made of carboxymethyl cellulose modified sodium silicate, prepared according to the following steps:

[0031] (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;

[0032] (2) Put carboxymethyl cellulose with a concentration of 8% in ethanol, add sodium silicate in the ratio of sodium silicate: carboxymethyl cellulose = 1:1, and disperse in carboxymethyl cellulose-ethanol solution, Obtain the carboxymethyl cellulose-ethanol solution containing sodium silicate, pull and dip the filter paper impregnated with aluminum sulfate described in step (1) in the ethanol solution of carboxymethyl cellulose-sodium silicate several times ; After that, air-dry for 24 hours to get it.

Embodiment 2

[0034] A kind of paper made of carboxymethyl cellulose modified sodium silicate, prepared according to the following steps:

[0035] (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 carboxymethyl cellulose with a concentration of 12% in ethanol, add sodium silicate to carboxymethyl cellulose in the ratio of sodium silicate: carboxymethyl cellulose = 1:4 In the plain-ethanol solution, ultrasonically oscillate for 8 min to obtain a carboxymethyl cellulose-ethanol solution containing sodium silicate, and use a paint scraper to coat the prepared carboxymethyl cellulose-ethanol solution on the surface of the filter paper. The amount of cloth should be controlled to 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.
