Description
Technical Field
The invention relates to the technical field of decorative materials, and provides dustproof and flame-retardant wallpaper and a preparation method thereof.
Background
The wallpaper is a common interior decoration material and is widely used for interior wall decoration of houses, offices, hotels and restaurants. However, most wallpaper on the market is easy to burn, and in recent years, indoor fire frequently occurs, and the application of wallpaper is accompanied with a great potential safety hazard. Along with the above, the demand of the flame-retardant wallpaper is increasingly urgent, and the flame-retardant wallpaper has a wide application prospect.
Enteromorpha is a marine chlorophyta plant, and has flame retardancy. The enteromorpha can be rapidly propagated and even abused to cause disasters when external conditions are appropriate, and the harmless treatment and the resource utilization of the enteromorpha have important significance. In the prior art, a treatment solution containing enteromorpha polysaccharide is obtained by a hot water extraction method, and a good effect is achieved by performing flame retardant finishing on cotton fabrics. Similarly, the flame retardant property of the wallpaper can be improved by treating the wallpaper with the enteromorpha polysaccharide extract.
It is known that enteromorpha polysaccharide obtained by hot water extraction method includes neutral polysaccharide and acidic polysaccharide, while acidic polysaccharide can be extracted specifically by alkali liquor extraction method. Because the acidic polysaccharide contains glucuronic acid and the ring of the acidic polysaccharide contains carboxyl, when the acidic polysaccharide is heated, the carboxyl can not only generate dehydration reaction with hydroxyl to generate water, but also generate decarboxylation reaction to generate carbon dioxide, which is beneficial to diluting the concentration of combustible gas and can play a role in inhibiting combustion in the initial stage, so the acidic polysaccharide has better flame retardant effect than neutral polysaccharide. Therefore, the acidic polysaccharide can be selectively extracted by an alkali liquor extraction method for flame retardance of the wallpaper.
However, since acidic polysaccharide has negative charges and dust in the air generally has positive charges, the acidic polysaccharide can attract and adhere the dust to wallpaper through electrostatic action, so that the wallpaper is easily stained with dust, and the application of the acidic polysaccharide in flame retardation of wallpaper is limited.
Disclosure of Invention
In order to overcome the defect that wallpaper after flame retardant treatment by using an enteromorpha acidic polysaccharide extracting solution is easy to be contaminated with dust, the invention provides the dustproof and flame retardant wallpaper and the preparation method thereof, and aims to enable the wallpaper to have good dustproof capability while improving the flame retardant property of the wallpaper by using the enteromorpha acidic polysaccharide extracting solution.
In order to achieve the purpose, the invention relates to the following specific technical scheme:
firstly, the invention provides a preparation method of dustproof and flame-retardant wallpaper, which comprises the following preparation steps:
(1) Adding enteromorpha powder into the composite extracting solution, heating and extracting for a certain time, and carrying out centrifugal separation while the solution is hot to obtain supernatant;
(2) Adding an auxiliary agent into the supernatant, and adjusting the pH to be neutral to obtain a dustproof and flame-retardant treatment solution;
(3) And spraying the treating fluid on the surface of the wallpaper, fully wetting the wallpaper, and drying to obtain the dustproof and flame-retardant wallpaper.
Wherein the composition of the compound extracting solution comprises basic amino acid, quaternary ammonium base and deionized water.
Preferably, the basic amino acid is one of lysine, arginine and histidine.
Preferably, the quaternary ammonium base is tetramethylammonium hydroxide.
Preferably, in the composite extracting solution, the concentration of the basic amino acid is 0.2 to 0.3mol/L, and the concentration of the quaternary ammonium base is 0.8 to 1.2mol/L.
Basic amino acids are amino acids with more basic than acidic groups, such as lysine, arginine, histidine. Wherein lysine contains 2 amino groups and 1 carboxyl group, arginine contains 1 amino group, 1 basic guanidino group and 1 carboxyl group, and histidine contains 1 amino group, 1 basic imidazolyl group and 1 carboxyl group. The quaternary ammonium base has the general formula R 4 NOH, wherein R are the same or different hydrocarbyl groups, the quaternary ammonium base having a strong basicity. When R is methyl, it is the simplest quaternary ammonium base, i.e., tetramethylammonium hydroxide.
Basic amino acids and quaternary ammonium bases are not only basic but also have a positive charge. Based on the method, alkaline amino acid, quaternary ammonium base and deionized water are adopted to form a composite extracting solution, and enteromorpha prolifera powder is extracted. In the compound extracting solution, even if the basic amino acid consumes partial alkali through the reaction of carboxyl and quaternary ammonium hydroxide, the mole number of the quaternary ammonium hydroxide is greatly higher than that of the basic amino acid, and the amino (guanidino or imidazolyl) of the basic amino acid can provide an alkaline environment, so that the compound extracting solution shows obvious alkalinity, and the acidic polysaccharide in the enteromorpha can be selectively extracted. Furthermore, compared with the common alkali liquor extraction method (taking sodium hydroxide solution as an extracting solution) in the prior research, the supernatant obtained after the extraction and centrifugation of the invention not only contains acidic polysaccharide, but also contains components in the composite extracting solution, and as the basic amino acid part and the quaternary ammonium base part both have positive charges, the surface of the wallpaper is positively charged, and dust in the air is also positively charged, so that the dust can be prevented from being adsorbed on the wallpaper through electrostatic repulsion, and the wallpaper is endowed with good dustproof capability. Furthermore, nitrogen-containing groups are introduced in the use of the basic amino acid and the quaternary ammonium base, and the generated gas can absorb heat, dilute oxygen and promote the expansion of a carbon layer during combustion, so that the carbon layer and the acidic polysaccharide can play a role in flame retardance, and the flame retardant effect of the wallpaper can be further improved.
The particle size of the enteromorpha powder is preferably 80-120 meshes, and the fresh enteromorpha is taken as a raw material, and the preparation process comprises the steps of cleaning, drying and crushing.
Preferably, the addition amount of the enteromorpha powder is 2 to 4 percent of the mass of the composite extracting solution.
Preferably, the heating temperature in the step (1) is 80 to 90 ℃ and the time is 2 to 4 hours.
Preferably, the rotation speed of the centrifugal separation in the step (1) is 4000 to 5000r/min, and the time is 10 to 15min.
The kind of the auxiliary agent can be selected according to the situation, and includes but is not limited to a mildew preventive. The addition amount of the mildew preventive is 0.2 to 0.4 percent of the mass of the supernatant.
Preferably, the spraying amount of the treatment liquid is 0.5 to 1.5 times of the mass of the wallpaper.
The invention also provides the dustproof and flame-retardant wallpaper prepared by the preparation method. The wallpaper is treated by dustproof and flame-retardant treatment liquid. The dustproof and flame-retardant treatment liquid is prepared by heating and extracting enteromorpha powder by using an alkaline composite extracting solution, then carrying out centrifugal separation, adding an auxiliary agent into supernate and adjusting the pH value. The composite extracting solution comprises basic amino acid, quaternary ammonium base and deionized water.
The invention provides dustproof and flame-retardant wallpaper and a preparation method thereof, and the excellent effects are as follows: the wallpaper prepared by the method disclosed by the invention has good flame retardant property and good dustproof property.
