Problems solved by technology

[0002] In the process of converting pure manual production to mechanized production of firecracker paper, there are often problems such as not bright enough color, the firecracker paper is not broken enough to achieve the red festive effect after the firecracker blasting, and the firecracker paper turns black after the firecracker blasting. The production of firecracker base paper can increase the output, but the above problems make high-end customers still favor firecracker paper produced by the original manual method, and the output of manual firecracker paper is low, which is far from meeting the current market demand

Embodiment Construction

[0020] The present invention will be further described below in conjunction with specific embodiment:

[0021] (1) waste paper pulp and bamboo pulp are mixed, and its mass ratio is 70%: 30%, and wherein the degree of beating of bamboo pulp is 20 ° SR, obtains mixed fiber raw material;

[0022] (2) Add bright red 4BS direct dye in the slurry mixing tank, the mass fraction of 4BS addition is 0.8% of dry pulp, after 7 minutes, add polyethyleneimine, the mass fraction of polyethyleneimine addition is dry 0.5% of slurry, keep for 6 minutes;

[0023] (3) The mixed fiber raw material after dyeing is refined, and the mass fraction is 4% slurry concentration and enters the refining section, before the refiner, according to the mass fraction of the addition of alkylamide imidazoline quaternary ammonium salt is absolute dry 0.3% of the pulp, the mass fraction of guanidine phosphate is 4% of the dry pulp, and both are added in the slurry online with a metering pump;

[0024] (4) After r...

Abstract

The invention relates to a producing method of firecracker paper as featured as hand-made paper mechanically produced. After bamboo pulp and fiber material of waste paper pulp are crushed and mixed to obtain mixture, direct red is added to the mixture, and urea resin or cationic PEI (polyethyleneimine) is added as dyeing auxiliary; swelling agent and flame retardant are added to firecracker paper pulp in the pulp grinding section; according to actual production conditions, the firecracker paper is produced through raw waste paper pulp and bamboo pulp ratio adjustment, pulp grinding control, pressing phase roll press adjustment and cylinder drying. Compared with the traditional firecracker paper mechanically produced, the firecracker paper has tightness decreased by 15%, tensile strength increased by 20% and colorimeter-measured redness increased by more than 30%; the problem that the firecracker paper mechanically produced is insufficiently red, fails to be completely broken after set off and becomes black is solved.

Description

technical field [0001] The invention relates to a preparation method of firecracker paper. technical background [0002] In the process of converting pure manual production to mechanized production of firecracker paper, there are often problems such as not bright enough color, the firecracker paper is not broken enough to achieve the red festive effect after the firecracker blasting, and the firecracker paper turns black after the firecracker blasting. The production of firecracker base paper can increase the output, but the above problems make high-end customers still favor firecracker paper produced by the original manual method, and the output of handmade firecracker paper is low, which is far from meeting the current market demand. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for preparing firecracker paper with the characteristics of hand-made firecracker paper by adopting a mechanical method. ...
