Fruit cultivating bag paper and preparation method thereof

Abstract

The invention relates to the field of fruit cultivating bag paper, in particular to fruit cultivating bag paper and a preparation method thereof. Raw paper is correspondingly smeared with an outer coating prepared from iron oxide yellow, iron oxide red, a color fixing agent, a waterproof agent and a water-resistance agent and an inner coating prepared from calcium carbonate, carbon black pigment, a color fixing agent and a waterproof agent, and the fruit cultivating bag paper is obtained through coiling. The fruit cultivating bag paper has good waterproof performance and high shading performance, coating distribution is uniform, and the performance of the fruit cultivating bag paper is excellent. In the production process of the fruit cultivating bag paper, pollution sources are effectively reduced, coating smearing is conducted through a coating method, the shading performance is uniform, and the shading degree is high; meanwhile, the technology is simple, operation is easy, the production cycle is short, and the production efficiency is high.

Description

technical field [0001] The invention relates to the field of fruit-raising bag paper, in particular to a kind of fruit-raising bag paper and a preparation method thereof. Background technique [0002] Fruit bag paper, also known as fruit bag paper, is a special paper used for fruit bagging. The biggest advantage of fruit bagging: first, it can reduce fruit diseases and insect pests and prevent pesticide residues on the fruit surface, making the fruit more delicious; second, it can effectively improve the appearance quality of the fruit, so that the fruit surface is smooth and bright, the coloring is uniform and comprehensive, and the coloring area can be enlarged. Reach more than 99%. [0003] Fruit bag paper is a kind of green environmental protection product, which has replaced the era of plastic film. This kind of paper has good air permeability, anti-aging and waterproof performance. It has been widely used in large fruit tree planting areas, and has been well received...

AI Technical Summary

Problems solved by technology

[0010] 1. Serious pollution

When the carbon black is poured, the fine carbon black particles rippling around, not only the operators have black hands, black faces and necks every day, including black mouth, nose, respiratory system and even the lungs, but also the carbon black particles cover the entire workshop, and the people who enter It's impossible to come out clean

[0011] 2. Uneven distribution of carbon black

[0012] 3. Poor shading degree of carbon black dyeing

At present, the carbon black used in fruit bag paper is not specially used for dyeing high or medium pigment carbon black, and even the low pigment carbon black worth about 10,000 yuan is rarely used. 1. The carbon black products after grinding rubber carbon black with coarser particles, because of the low grinding fineness, different particle sizes, and limited dyeing power, the carbon black particles of the fruit bag paper produced cannot be densely distributed and evenly covered. You will see that the shading is deep and shallow, and there will be transparent spots caused by coarse particles
