Embodiment Construction

[0024]Put reed leaves and reed stalks into a beaker at a mass ratio of 1:4, impregnate the reed leaves and reed stalks with hydrochloric acid with a mass fraction of 8-12%, place the beaker in an ultrasonic oscillator, and set the beaker at an ultrasonic frequency of 35-38kHz. Shake for 4-6 hours under the same conditions, filter to obtain filter residue after shaking, wash 3-5 times with distilled water, put it into a grinder and grind for 1-2 hours to obtain a ground product; mix the above-mentioned ground product with 40-50% acetic acid Put the solution into a beaker and mix evenly to obtain a suspension, add citric acid crystals with a mass of 12-15% of the suspension to the beaker, and mix and stir with a stirrer at a speed of 500-550r / min for 30-40min to obtain a mixed solution , put the mixed solution in a high-temperature and high-pressure reactor, and react at a constant temperature and pressure for 30-40 minutes at a temperature of 180-200°C and an air pressure of 1.5...

Abstract

The invention relates to a preparation method of a waterproof type high-toughness coating material and belongs to the technical field of preparation of coating materials. The preparation method comprises the following steps: taking reed leaves and reed stems as raw materials to prepare a reaction solution; then adding chitosan, potassium permanganate and the like into the reaction solution and concentrating to obtain reaction gel; enabling a mixed product and de-ionized water to react to obtain a calcined product; and finally, mixing the calcined product and an organic matter at high temperature to obtain the waterproof type high-toughness coating material. According to the preparation method, a lot of carboxyl groups are grafted outside and inside a plant fiber pipe under a common effectof acetic acid and citric acid, and the added chitosan is firmly adsorbed on fibers, so that the specific surface area is enlarged and the adhesion effect is improved; glycerol and the carboxyl groupson the surfaces of the plant fibers are subjected to esterification reaction; and the bonding degree of silicon dioxide and the plant fibers is further enhanced by utilizing high temperature, so thatthe waterproof performance and mechanical properties of the coating material are comprehensively improved, and the coating material has a wide application prospect.

Description

technical field [0001] The invention relates to a preparation method of a waterproof high-toughness coating material, which belongs to the technical field of coating material preparation. Background technique [0002] Film coating is one of the major achievements in the development of advanced preparation technology in recent years. It is considered to be a technology with strong technology, high difficulty and great impact on product quality. It usually refers to the coating of sugar or other film-forming materials on the outer surface of pharmaceutical solid preparations by using specific coating equipment, so that after drying, it becomes one or several layers of different thicknesses and different elasticity closely adhered to the surface. Multi-functional protective layer technology, [0003] Film coating materials generally meet the following conditions: non-toxic, non-chemically inert, stable in heat, light, moisture, and air, do not react with the coating drug, can ...
