Embodiment 1

[0025] Example 1 The fiber raw material for preparing large seed bag paper is 100 kg softwood pulp. In this embodiment, the enhancer is cationic starch, and the added amount is 1.5 kg.

[0026] The preparation method of the large seed bag paper for agriculture is as follows: 1) Add tap water and cationic starch into a barrel with a jacketed heating and stirring device to prepare an aqueous solution with a concentration of 4% by mass, and gelatinize (slowly under stirring Heat to 92℃, keep for 25min) and make a gelatinized liquid for use; 2) Put 100kg softwood pulp into a beater that has stored 2400kg tap water. The mass concentration of fiber in the water is 4%. First, dissolve for 20min. Then beat with a knife to 35°SR, and the wet weight of fiber is 9.1 grams. Start the knife and put the slurry into the mixing tank; 3) Put the gelatinized cationic starch gelatinization liquid in step 1) and press it to dry Add 1.5kg to calculate the amount of liquid needed to be added, and add...

Embodiment 2

[0027] Example 2 The fiber raw material for preparing large seed bag paper is 100 kg of cotton pulp. In this embodiment, the enhancer is cationic starch, and the added amount is 1 kg. The preparation method of the large-seed bag paper for agriculture is as follows: 1) Add tap water and cationic starch into a barrel with a jacketed heating and stirring device to prepare an aqueous solution with a concentration of 4% by mass, and gelatinize (heat slowly under stirring) After the temperature reaches 92℃, heat preservation for 25min), it will be made into a gelatinized liquid for use; 2) Put 100kg of cotton pulp into a beater that has stored 2400kg of tap water, and the fiber concentration in the water is 4%. Disperse and disperse for 20 minutes, and then beat with a knife to 30°SR, wet weight 8.5 grams, and then put the slurry into the mixing tank; 3) Put the gelatinized cationic starch gelatinization liquid in step 1), Calculate the amount of liquid needed to be added according ...

Embodiment 3

[0028] Example 3 The fiber raw material for preparing large seed bag paper is 100 kg of hardwood pulp. In this embodiment, the enhancer is cationic starch, and the added amount is 1 kg. The preparation method of the large-seed bag paper for agriculture is as follows: 1) Add tap water and cationic starch into a barrel with a jacketed heating and stirring device to prepare an aqueous solution with a concentration of 4% by mass, and gelatinize (heat slowly under stirring) After reaching 92℃, heat preservation for 25min), it will be made into a gelatinized liquid for use; 2) Put 100kg of hardwood pulp into a beater that has stored 2400kg of tap water, and the fiber concentration in the water is 4%. First disperse and disperse for 20 minutes, and then beat with a knife to a degree of percussion of 32°SR, wet weight 6.1 grams, and then start the knife to put the slurry into the mixing tank; 3) Gelatinize the gelatinized cationic starch in step 1) Liquid, calculate the amount of liqu...

Abstract

Belonging to the technical field of specialty paper manufacturing, the invention discloses an agricultural big seed bag paper and a preparation method thereof. The agricultural big seed bag paper comprises a plant fiber raw material and an auxiliary material. The plant fiber raw material and a reinforcing agent are in a weight part ratio of 100:1-4 (absolute dry weight). The beating degree of theplant fiber subjected to beating treatment is 25degree SR-50degree SR, and the wet weight range of the fiber is 6.0g-14.0g. The pulp subjected to beating treatment is added with water to be prepared into a 0.25%-0.35% slurry, a reinforcing agent is employed for reinforcement, and an inclined net papermaking machine wet papermaking process is adopted for preparation. The seed bag paper has the characteristics of low quantity, high dry strength and high bursting strength, etc., can meet the processing performance requirements of processing radish, green pepper and other large-particle size seedsinto seed ropes, seeding test shows that the obtained seed ropes have high seed emergence rate, fast paper decomposition speed and no pollution to soil, and meets the green and environmental protection requirements.

Description

Technical field [0001] The invention belongs to the technical field of special paper and its manufacturing method, and specifically relates to a large seed bag paper for agriculture and a preparation method thereof. Background technique [0002] Precision seeding is the key to precision agriculture. Seed bag paper is a supporting paper for precise sowing. Special equipment for processing seed bags is used to wrap plant seeds in paper at a certain distance to make rope-shaped seed bags. The spacing of seeds in the seed bag can be accurate to centimeters and millimeters. When the precision seeding seed bag is sowed into the ground with a precision seeder, the paper absorbs the water in the ground, starts to decompose, and provides the water and decomposition products as nutrients to the seeds for germination. The use of the above-mentioned seeding technology can not only save a large number of high-quality seeds and labor costs, but also enable crops to be optimally distributed i...
