Water-proof agent for fruit cultivating bag paper and preparation method and application thereof

Abstract

The invention discloses a water-proof agent for fruit cultivating bag paper and a preparation method and application thereof. The water-proof agent for the fruit cultivating bag paper comprises the following components: reactive polysiloxane, an emulsifier and deionized water. One or both of a wet strength agent and emulsion paraffin can be added into the components so as to enhance the wrinkle resistance of paper sheets. The invention also discloses the application of the water-proof agent for the fruit cultivating bag paper in enhancing of the waterproofness of raw fruit cultivating bag paper. The water-proof agent is applied by the following steps of: diluting the water-proof agent for the fruit cultivating bag paper with water; soaking the raw fruit cultivating bag paper; and drying. The performances such as water resistance, waterproofness, air permeability, wrinkle resistance and the like of the raw fruit cultivating bag paper treated by the water-proof agent for the fruit cultivating bag paper are remarkably improved or enhanced. The water-proof agent has a short degradation period, and meets requirements for fruit cultivating period and environmental protection.

Description

technical field [0001] The invention relates to a water repellant, in particular to a water repellant for fruit bag paper and a preparation method thereof. The invention also relates to the use of the water repellant for fruit bag paper as a special water repellant for fruit bag paper, which belongs to the field of water repellent for fruit bag paper. Background technique [0002] In recent years, due to the remarkable improvement of people's living standards and the great increase in the market demand for high-quality, pollution-free fruits. It has become a development trend to use bagging protection during the whole process of fruit growth. The use of bagging to grow fruit can prevent the pollution of pesticides to the fruit, reduce the impact of ultraviolet rays, wind and sand, and pests and diseases on the fruit, so that the appearance of the fruit is fresh and beautiful, and the inner meat is tender and crisp, with sufficient water. It can improve the yield of high-qua...

Problems solved by technology

Most of the methods in China are coated with paraffin wax coating, which is low in cost and easy to operate, but the effect is not good. The typical problem is that the fruit is prone to "internal burning" due to the poor air permeability of the fruit bag paper, resulting in a decline in fruit quality or rot. , and this kind of fruit bag paper is difficult to degrade in a short time

Reactive products are mostly used in foreign countries, and the price of fluorine-containing waterproofing agents is high. Although the effect is excellent, it is not suitable for domestic conditions.

There are also some imported silicone fruit bag paper waterproofing agents used in China, but the cost is relatively high
