Preparation method of water-resistant fruit-cultivating bag paper material

Abstract

The invention relates to a preparation method of a water-resistant fruit-cultivating bag paper material, and belongs to the technical field of materials. According to the method provided by the invention, cationic dispersion rosin size and a paraffin emulsion are added to prepare the water-resistant fruit-cultivating bag paper material, the cationic dispersion rosin size is an inexpensive and extremely abundant resource, molecules of the cationic dispersion rosin size contain alkyl with a long carbon chain and good water resistance, so that the cationic dispersion rosin size can give water andoil resistance to the paper, improve phenomena of yellowing and brittleness of the paper, improve the durability, strength and whiteness of the paper, and reduce a sizing obstacle in summer, therebyimproving each performance indicator and quality of the paper; free rosin particles can react with aluminum ions on fibers, so that hydrophilic and hydrophobic groups of the rosin particles are turnedand positioned, the rosin particles and the fibers are firmly combined, the fibers are not decomposed for a long time, the storage time is long, and therefore the durability and stability of the fruit-cultivating bag paper material are improved.

Description

technical field

[0001] The invention relates to a preparation method of a water-resistant fruit-growing bag paper material, which belongs to the field of material technology. Background technique

[0002] Fruit bag paper is a special paper that provides protection during the whole process of fruit development. It is an agricultural technical paper with high added value. It must have high water resistance and durability, and also have good air permeability. Moreover, fruit farmers have strict requirements on the price of fruit bag paper, so they should reduce production costs as much as possible.

[0003] The fruit bagging technology was first produced in Japan. Simply put, it is a technology for bagging protection during the whole process of fruit growth and development. It has a history of more than 100 years. In the early 20th century, in order to prevent pest damage, Japanese fruit farmers mainly carried out fruit bagging on grapes and pears, and it was not extended to a...
