example 1

[0023]Mix calcium nitrate and water in a beaker at a mass ratio of 1:100, and add urea 3 times the mass of calcium nitrate and 0.8 times the mass of Bacillus pasteurianus into the beaker at a temperature of 35°C and a rotational speed of 300r / min After stirring and mixing for 80 minutes under the condition of 35°C, the mixture was obtained after standing at constant temperature for 2 hours. The mixture was transferred to a rotary evaporator, and the temperature was 65°C, the rotation speed was 150r / min, and the pressure was 600kPa. After rotary steaming and concentration for 2 hours, the rotary steamed product was obtained, and the rotary steamed product was dried at a temperature of 85°C for 40 minutes to obtain the pretreated filler; the pretreated filler was moved into the carbonization furnace, and the carbonization furnace was fed at a rate of 25mL / min Nitrogen, after low-temperature carbonization at 450°C for 45 minutes, to obtain carbonized filler, mix carbonized filler ...

Abstract

The invention discloses a preparation method of light-weight tensile rich mineral paper, and belongs to the technical field of high polymer materials. The method comprises the steps that polyethyleneis mixed with modified filler, and mixed with starch polyvinyl alcohol mixture, graphene oxide and modified paraffin in sequence, the mixture is stirred and mixed to obtain a base paper layer mixture,banburying, prilling, extrusion and stretching are carried out on the base paper layer mixture to obtain a base paper layer, and corona treatment is carried out on the base paper layer to obtain a pretreated base paper layer; 15-18 parts of polylactic acid, 30-40 parts of water, 2-3 parts of ammonium hydroxide, 1-2 parts of antistatic agent and 8-10 parts of lithopone are weighed by weight in sequence, the polylactic acid is mixed with the water, and mixed with the ammonium hydroxide, the lithopone and the antistatic agent in sequence, the mixture is stirred and mixed to obtain a coating material; and the coating material is applied on both faces of base layer paper with a coating amount of 10-30 grams per square meter to obtain the light-weight tensile rich mineral paper. The light-weight tensile rich mineral paper prepared by the technical scheme has low density, light mass, and excellent tension resistance performance.

Description

technical field [0001] The invention discloses a preparation method of lightweight tensile stone paper, which belongs to the technical field of polymer materials. Background technique [0002] As one of the most important printing materials in printing reproduction, paper has always been popular because of its good printability. However, while traditional paper brings convenience to people's lives, it also has a great impact on the environment. Stone paper is mainly made of inorganic fillers as raw materials, which usually account for the production components, and the rest are organic polymers that are granulated at high temperature, and then processed into required paper through calendering, stretching, casting and other production processes. Stone paper series products have the characteristics of waterproof, moisture-proof, folding resistance, anti-corrosion, insect-proof, anti-freeze, flame-retardant, non-toxic, etc., and have broad applications in many fields such as b...
