Process for preparing fruit and vegetable fresh-keeping paper made from tourmaline

Abstract

The invention involves a preparation method of fruit and vegetable tourmaline preservation paper and it includes: preparing the tourmaline slurry which particle diameter is 1 -3 microns after the tourmaline crude ore is initial separated, disintegrated, cleaned, magnetic cubed, wet agitated and wet grained; adding the 1-5% tourmaline slurry in to the corrugated paper pulp or the packing paper pulp which percentage by weight is 95-98%, then mixing the paper pulp and the coupling agent which percentage by weight is 0.1% uniform as the paper making raw materials and sending it into the corrugated paper making process line, so preparing the corrugated paper used in packing chest or the polished wrapping paper. The fruit and vegetable tourmaline preservation paper can release negative ions and far infrared rays, it can delay fruit and vegetable respiration, inhibit and kill harmful bacteria, reduce the permeability of the paper, prevent fruits and vegetables evaporating water; the light transmittance is very poor, so it avoids light irradiating the fruit and vegetable to fresh-keeping. It can be used repeatedly, the operation is simple, cost is low, the tourmaline preservation papers used do not cause white pollution, because tourmaline contains about 8.5% of boron which is a fertilizer can develop plant roots.

Description

technical field [0001] The invention relates to a fresh-keeping paper, in particular to a preparation method of a fruit and vegetable tourmaline fresh-keeping paper. Background technique [0002] With the continuous improvement of people's material culture and living standards, the awareness and requirements for health and environmental protection are also continuously strengthened, especially the preservation of fruits, vegetables and other foods that are consumed every day has attracted the attention of fruit farmers, merchants and consumers. At present, in the storage and transportation of fruits and vegetables, the main methods of fresh-keeping are sulfur dioxide airtight fumigation and plastic plastic wrap to prevent water evaporation; The equipment is simple and easy to operate, and the cost is low, but it cannot be sterilized and anti-corrosion and is airtight, which can easily lead to mildew and rot of fruits and vegetables, and discarded plastic cling film will caus...
