Abstract

The invention discloses a preparation method of environment-friendly wallpaper, which comprises the steps of firstly preparing mixed emulsion, then extracting fibrilia from jute and ramie, and preparing the wallpaper after mixing.

Description

Preparation method of environment-friendly wallpaper
Technical Field
The invention belongs to the technical field of decorative materials, and particularly relates to a preparation method of environment-friendly wallpaper.
Background
Wallpaper, also known as wallpaper, is an interior decoration material that is widely used. Because the wallpaper has the characteristics of various colors, rich patterns, luxury, safety, environmental protection, convenient construction, proper price and the like which are incomparable with various other interior decoration materials, the wallpaper is popularized to a great extent in many countries and regions.
Wallpaper is an important component of modern interior decoration materials, has the main advantages of various colors, rich patterns, proper price, dirt resistance, scrubbing resistance and the like, and is widely popular among people. Along with the development of society and the continuous improvement of living standard of people, people also have higher and higher requirements on wallpaper, various wallpapers with special functions appear, people pay more attention to the environmental protection problem in the decoration at present, but formaldehyde is often contained in the existing wallpaper processing process, and the formaldehyde can cause damage to human bodies.
Disclosure of Invention
The invention aims to provide a preparation method of environment-friendly wallpaper, aiming at the existing problems.
The invention is realized by the following technical scheme:
a preparation method of environment-friendly wallpaper comprises the following specific preparation steps:
1) taking 320 parts of PVC paste resin 280-containing materials, 10-30 parts of cyclodextrin and 5-10 parts of polyethylene glycol, mixing, adding 20-30 parts of deionized water, stirring, adding 10-20 parts of silica sol after complete dispersion, mixing, pouring into an oscillation stirrer, stirring, and oscillating for 30-50min to obtain mixed emulsion;
2) taking 30-50 parts of jute skin and 20-30 parts of ramie skin, putting the outer skin into boiling water for cooking, wherein the cooking time is 5-7 hours, adding 5.2 parts of sodium bicarbonate and 2.5 parts of sodium tripolyphosphate into every 100 parts of the cooked water during cooking, crushing and decomposing the mixture into filaments after the cooking is finished, putting the obtained filaments into aqueous solution of pectinase and cellulase for soaking, filtering, then putting the filaments into a vacuum container for drying at the temperature of 50-80 ℃, and obtaining the fibrilia after the drying is finished;
3) adding fibrilia into the mixed emulsion in 1), mixing, placing into an ultrasonic water bath oscillator for oscillation at 50-70 deg.C for 30-40min, and pouring the slurry after oscillation into a forming machine for extrusion molding.
In the step (2), the weight ratio of the pectinase to the cellulase is 1: 1.5.
The concentration of the pectinase is 7.2 u/mL.
The environment-friendly wallpaper prepared by the invention uses PVC paste resin as a main raw material, adopts cyclodextrin, silica sol and other components as a binder, simultaneously adds a large amount of fibrilia into the wallpaper raw material, and prepares the wallpaper by combining plant fiber components with chemical synthetic resin, so that not only can the strength and the wear resistance of the wallpaper reach the requirements, but also the environment-friendly property of the prepared wallpaper is obviously improved.
