Problems solved by technology

[0008]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

[0029] A kind of paper made of solid paraffin modified nano silicon dioxide, prepared according to the following steps:

[0030] (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;

[0031] (2) Put the solid paraffin with a concentration of 6% in ethanol, add nano-silica and disperse it in the solid paraffin-ethanol solution according to the ratio of nano-silica:paraffin wax=1:1, and obtain nano-silica-containing Solid paraffin-ethanol solution, the filter paper impregnated with aluminum sulfate described in step (1), is dipped several times in the solid paraffin-nano-silicon dioxide ethanol solution; after that, it is air-dried for 24 hours to obtain.

Embodiment 2

[0033] A kind of paper made of solid paraffin modified nano silicon dioxide, prepared according to the following steps:

[0034] (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 Dry the number at C; (2) Put the solid paraffin with a concentration of 10% in ethanol, add nano-silica and disperse it in the solid paraffin-ethanol solution according to the ratio of nano-silica: solid paraffin = 1:4, and ultrasonically Shake for 8 minutes to obtain a solid paraffin-ethanol solution containing nano-silica, and use a paint scraper to coat the prepared solid paraffin-ethanol solution on the surface of the filter paper, and the coating amount should be controlled at 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 solid paraffin modified nanometer silica. 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 solid paraffin with a concentration of 6-10% to ethanol, adding nanometer silica according to a ratio of the nanometer silica to the solid paraffin of 1:1-1:4, dispersing into the solid paraffin-ethanol solution to obtain the solid paraffin-ethanol solution containing the nanometer silica, carrying out pulling dipping on the filtration paper obtained in the step (1) in the solid paraffin-nanometer silica 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 solid paraffin modified nano silicon dioxide and a preparation method thereof. Background technique [0002] Paraffin wax, also known as crystalline wax, is usually a white, colorless, odorless waxy solid that melts at 47°C-64°C and has a density of about 0.9g / cm 3 , Soluble in non-polar solvents such as gasoline, carbon disulfide, xylene, ether, benzene, chloroform, carbon tetrachloride, naphtha, etc., insoluble in polar solvents such as water and methanol. Pure paraffin is a good insulator, with a resistivity of 1013-1017 ohm-meters, which is higher than most materials except some plastics (notably Teflon). Paraffin is also a good heat storage material, with a specific heat capacity of 2.14–2.9 J g –1 ·K –1 , heat of fusion 200–220J·g –1 . After soaking the paper in paraffin, various wax papers with good waterproof properties can be prepared, which can be used i...
