Problems solved by technology

[0003] Judging from the existing technology, humidification equipment or green vegetation are generally used for indoor moisturizing, and it is rare to use moisturizing materials for air humidity regulation; and the concept of moisturizing flower pots has been around for many years, but basically they are flower pots. The improved design of the pot structure increases the complexity of the flower pot structure, and also increases the production cost and selling price of the flower pot

Embodiment 1

[0016] The method for the preparation of embodiment 1 acrylic acid moisturizing composite material

[0017] Silica gel powder preparation: take 150ml of water glass and place it in a container, slowly add H with a concentration of about 25% under stirring conditions 2 SO 4 Solution to water glass to form a gel; dry the water glass gel at 50-65°C for 8-10 hours to form white loose particles, grind it into 80-200 mesh powder with a mortar for later use;

[0018] Preparation of acrylic acid moisture-retaining composite material sample: configure NaOH solution according to the mass ratio of water and sodium hydroxide of 12:1; Stir well; then add N,N-methylene acrylamide, ammonium persulfate, bentonite and silica gel powder according to the mass parts shown in Table 1, and stir well; heat at 70-80°C, after fully After the reaction, the sample was taken out from the beaker and placed in an oven, and dried at 50-60°C for 2-6 hours to constant weight.

Embodiment 2

[0021] The structure and performance of embodiment 2 acrylic acid moisturizing composite material

[0022] The structure of the composite material: the acrylic moisture-retaining composite material presents a porous structure, such as figure 1 Shown is the electron micrograph of the composite material.

[0023] Water absorption and dehydration properties of composite materials: As shown in the above-mentioned Table 1, the content of silica gel powder in the first 5 groups of experiments increased sequentially, and the content of bentonite in the last 5 groups of experiments increased in sequence, and water absorption and dehydration experiments were carried out at 20°C and 40°C respectively. As shown in Table 2 and Table 3.

Abstract

The invention discloses a preparation method of an acrylic acid moisturizing composite material which comprises the following components in part by weight: 100 parts of acrylic acid, 60 parts of water, 20 parts of NaOH solution, 0.5 parts of N,N-methylene acrylic amide, 4 parts of ammonium persulfate, 20 to 100 parts of bentonite, and 40 to 80 parts of silica-gel powder. The moisturizing material has the characteristics of high water absorption, good water retention effect, low density and easiness in forming, and can be applied to moisturizing application fields, such as interior moisturizing decoration, flowerpot moisturizing layers, and the like.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a method for preparing an acrylic moisturizing composite material Background technique [0002] Due to people's higher requirements for living and working environments, or the objective limitations of certain production and experimental conditions, dehumidification or humidification equipment has a wider application market. If a moisturizing material is used to regulate humidity and applied to the field of interior decoration, it will be able to automatically adjust the air humidity of the indoor environment, improve human comfort, and improve production and experimental conditions; at the same time, the moisturizing material can also It can be used as a moisture-retaining layer for flowerpots to adjust the humidity of the soil and prolong the moisture retention time, so that more vegetation is suitable for balcony and indoor greening. [0003] Judging from the existing te...
