Abstract

The invention discloses brown impregnated bond paper and a manufacturing process thereof, and relates to the technical field of papermaking. The brown impregnated bond paper comprises the following raw materials by weight: 1000 parts of waste printing paper, 146-150 parts of a pigment, 113-127 parts of stone powder, 50-55 parts of a wet strength agent, 20-25 parts of alum, 20-24 parts of an antibacterial agent, and 6-10 parts of other additives; wherein the antibacterial agent is prepared from the following raw materials in parts by weight: 10 to 14% of green tea extracting solution, 10 to 14%of Schefflera octophylla extracting solution, 10 to 14% of folium artemisiae argyi extracting solution, 10 to 14% of chitosan, 20 to 24% of calcined bentonite, 1 to 5% of a coupling agent and the balance of water. By adding the wet strength agent and the antibacterial agent for compounding with the other raw materials, the water absorption rate of the reproduced paper is reduced, the wet strengthof the reproduced paper is improved, and meanwhile, the reproduced paper is endowed with good antibacterial performance, so that the use effect of the building template paper is improved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a palm paper and a manufacturing process thereof. Background technique [0002] Architectural template paper, also known as laminated paper, is impregnated paper impregnated with amino resin (mainly melamine resin) or phenolic resin and dried to a certain degree of curing by special paper. Existing building formwork paper generally has three colors of red, brown and black. [0003] To reduce deforestation, recycling waste paper into paper is becoming more and more popular. [0004] The printing and dyeing industry in Zhejiang is well developed, which will produce a large amount of printing waste paper in the process of transfer printing. The surface of these discarded printed papers is generally white and clean, and the surface contains less ink, and generally does not need to be deinked, so it is a good raw material for paper recycling. [0005] However, the existing rema...
