specific Embodiment approach 1

[0015] Specific embodiment 1: The preparation method of the self-heating heat storage thermal insulation paper of this embodiment is carried out according to the following steps:

[0016] 1. Mix 5%-10% carbon black, 20%-30% zirconium carbide and 60%-75% alumina according to mass percentage to obtain a filler mixture;

[0017] 2. Add the retention aid and filler mixture to the pulp and mix evenly to obtain the paper material, which is then made and dried to obtain self-heating heat storage insulation paper; the mass of the filler mixture accounts for 5 of the dry weight of the solids in the paper material %~10%.

specific Embodiment approach 2

[0018] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the retention aid is polyethyleneimine and / or attapulgite; the others are the same as Embodiment 1.

specific Embodiment approach 3

[0019] Specific embodiment three: This embodiment is different from specific embodiment two in that the mass of polyethyleneimine accounts for 1% to 2% of the dry weight of the solid phase in the paper material, and the mass of attapulgite accounts for the solid phase in the paper material 2% to 3% of dry weight; others are the same as the second embodiment.

Abstract

The invention relates to a preparation method for self-heating heat-storage heat-insulation paper, relates to the field of special paper materials, and aims to solve the technical problem that currentthermal-storage paper has poor flexibility and high costs. The method comprises the following steps: uniformly mixing carbon black, zirconium carbide and aluminum oxide to obtain a filler mixture; adding the filler mixture into paper pulp through an internal filling method, performing papermaking, and performing drying to obtain the self-heating heat-storage heat-insulation paper; or uniformly mixing carbon black, zirconium carbide and aluminum oxide to obtain a pigment mixture; and preparing a coating from the pigment mixture, coating the surface of paper by a coating method, and performingdrying to obtain the self-heating heat-storage heat-insulation paper. According to the self-heating heat-storage heat-insulation paper prepared by the internal filling method provided by the invention, the toughness is improved by 10%-13% and the strength is improved by 5%-7% than those of blank paper without the filler mixture; according to the self-heating heat-storage heat-insulation paper prepared by the coating method, the toughness is improved by 28%-33% and the strength is improved by 25%-27% than those of paper as a substrate; and the paper provided by the invention can be used in thefield of heat-insulation materials.

Description

Technical field [0001] The invention relates to the field of special paper materials, in particular to a new method for preparing self-heating heat storage and heat preservation paper. Background technique [0002] Self-heating heat storage insulation paper is to use self-heating fillers or pigments in the papermaking process to fill or special post-processing the paper, so that the paper can absorb solar energy, convert light energy into heat energy and store it, thereby giving Paper has the function of storing heat and keeping warm. In practical applications, if the outdoor pipeline is covered with self-heating heat storage insulation paper, the continuous heat collection of the self-heating heat storage insulation paper can prevent freezing and heat dissipation of the pipeline in winter; use self-heating heat storage insulation paper instead Plastic mulch can not only maintain surface moisture to prevent evaporation, prevent soil freezing in winter, increase the germination r...
