Problems solved by technology

However, the harm reduction effect of single calcium carbonate is limited, and the retention rate of calcium carbonate in the existing tipping paper base paper processing technology is low, which not only limits the adsorption and harm reduction performance of tipping paper, but also causes the loss of paper strength and appearance quality. decline

Embodiment Construction

[0017] A preparation method of tipping paper base paper, comprising the following steps:

[0018] (1) The coniferous wood pulp and the hardwood pulp are beaten and mixed evenly to obtain tipping pulp, and the weight ratio of the softwood pulp to the hardwood pulp is 1:0.8;

[0019] (2) Mix calcium carbonate, nano-titanium dioxide, and sodium hydroxide solution at a weight ratio of 1:0.5:10, then put them into a closed high-pressure reactor, and keep warm at 120°C for 24 hours. After cooling and filtering, use the obtained solid Washing with distilled water, and then drying at 100°C for 10 hours to obtain tipping paper filler;

[0020] (3) Add the tipping paper filler, sizing agent and retention aid described in step (2) successively to the tipping paper slurry described in step (1) and mix evenly, and then after forming, drying and calendering The tipping paper base paper is obtained after the treatment, and the weight ratio of the tipping paper slurry, the tipping paper fill...

Abstract

The invention discloses a preparation method of tipping paper body paper. The preparation method comprises the following steps: respectively pulping softwood pulp and hardwood pulp, uniformly mixing to obtain tipping paper pulp, collectively adding calcium carbonate and nano titanium dioxide into a sodium hydroxide solution, growing a titanium dioxide naontube on the surface of the calcium carbonate by hydrothermal reaction, drying to obtain tipping paper filler, then mixing the tipping paper pulp, the tipping paper filler, a sizing agent and a retention aid, making molding, drying, and calendaring to obtain the tipping paper body paper. The tipping paper body paper prepared by the method has excellent mechanical strength and appearance quality, also has an efficacy of reducing tar and harm, and is applicable to a top-grade cigarette packaging material.

Description

technical field [0001] The invention relates to the technical field of cigarette materials, in particular to a method for preparing tipping paper base paper. Background technique [0002] Tipping paper, also known as tipping paper, is a packaging material for cigarettes and is used as the outer packaging of filters. Tipping paper is a kind of decorative paper obtained by printing, coating and other processing of tipping base paper, which mainly plays a role in improving the appearance of cigarettes. In recent years, with the growing demand for health and environmental protection of cigarettes, the role of tipping paper is not limited to packaging and decoration, but also puts forward higher requirements for health and environmental protection and its role in reducing tar and harm of cigarettes . Calcium carbonate, as a commonly used filler for tipping paper base paper, can not only improve the strength and appearance quality of tipping paper base paper, but also has a cert...
