Description
Technical Field
The invention relates to the technical field of dustproof green nets, in particular to a degradable biological dustproof green net.
Background
With the popularization of urban hardening, dirt roads and bare ground in cities become less and less. However, exposed open spaces generated by eliminating part of buildings in urban development or exposed open spaces which cannot be used recently still exist. The existence of bare space must be accompanied by raise dust, air pollution phenomenon, in order to protect the environment, reduces pm2.5, and dustproof green net has obtained wide application, and its fine solution raise dust problem has reduced the influence that the space temporarily can't use peripheral resident.
However, the existing dustproof green nets are all made of non-degradable materials, and are easy to evolve into plastic wastes. The dust-proof green screen is evolved into garbage due to two factors: 1. time factors, long-time wind and sun exposure, serious erosion and serious damage; 2. people can clean the green net and the construction waste together due to human factors, so that time and labor are saved. It can be seen that the existing dustproof green net has a great effect on preventing dust emission, but the existing dustproof green net can not only address the symptoms but also prevent the root causes, and can bring more non-degradable garbage after dust prevention, so that the dust is not compensated, and the foundation of protecting the environment is also abandoned.
The super absorbent resin contains a large number of strong hydrophilic groups such as amino, carboxyl, hydroxyl and the like and a unique three-dimensional network structure, has chelation on metal, and is a novel functional polymer material. The super absorbent resin can rapidly absorb liquid water which is hundreds of times or even thousands of times higher than the self-quality water through hydration, has good water retention capacity at normal temperature, is not easy to lose water even being heated or pressed, and has good stability in light, heat, acid and alkali. Therefore, compared with the traditional water absorption material, the super absorbent resin has the advantages of low crosslinking density, high water absorption expansion, high water retention property, strong absorption to weak alkaline substances, insolubility in water and organic solvents, repeated use and the like. As a novel multifunctional material, the super absorbent resin has wide application in the fields of agriculture, forestry, gardening, health care, building material industry and the like.
The superabsorbent resins can be classified into four major categories according to the source of the raw materials: starches, celluloses, synthetic resins, and organic-inorganic composites: (1) starch-based super absorbent resin: mainly refers to a kind of high molecular material formed by graft copolymerization of starch as skeleton and other monomers, which is the first discovered high water absorption resin kind, and is generally obtained by modifying natural starch. The starch-based super absorbent resin usually takes wheat starch, corn starch, potato starch and the like as basic raw materials, the raw materials are visible everywhere in life, and not only have wide sources and low production cost, but also are biomass and generally can be degraded by microorganisms, so the starch-based super absorbent resin is an environment-friendly material. (2) Cellulose-based super absorbent resin: like starch, cellulose is one of the most widely distributed and abundant biomass raw materials in nature. The natural cellulose molecule contains a large amount of hydrophilic groups, has a rigid flat structure, and is internally provided with a plurality of capillaries, so that the specific surface area of the material can be increased, and the characteristics make the material very suitable for being used as a water absorption material. The cellulose is a natural renewable resource, can be continuously utilized, and has the advantages of no toxicity, degradability, environmental compatibility and the like, so the fiber super absorbent resin has wide application prospect. (3) Synthetic resin-based super absorbent resin: unlike starch-based and cellulose-based super absorbent resins, synthetic resin-based super absorbent resins have a large number of hydrophilic groups and a network structure formed by crosslinking on the molecular chains, so that the material can rapidly absorb water and retain water in the network structure. Petrochemical products bring a large amount of raw materials for the production of the super absorbent resin, and the raw materials are rich and easy to obtain, and are simple and convenient to prepare, such as polyvinyl alcohol, polyacrylic acid, polyacrylamide and the like. The synthetic super absorbent resin has high water absorption rate, but is easily influenced by pH value and salinity, has small gel strength after water absorption, and has poor salt resistance and biodegradability, so that environmental pollution is easily caused after the waste, and the application range of the water absorbent material is greatly limited. The most widely used synthetic super absorbent resin is polyacrylate series, and polyvinyl alcohol series is the next. (4) Organic-inorganic composite super absorbent resin: in order to overcome the problems of complex production process, low gel strength, difficult recycling of synthetic resin super absorbent resin and the like of starch and cellulose super absorbent resin, a new functional group is introduced into natural resin and synthetic resin or the comprehensive performance of the resin is improved by means of blending and the like, so that a degradable, high-performance and multifunctional composite super absorbent resin is obtained, and the development direction of the super absorbent resin is developed. The composite materials can be classified into organic/inorganic composite super absorbent resin and organic/organic composite super absorbent resin according to their kinds.
Therefore, the new material of the super absorbent resin can be applied to the production of the dustproof green screen to solve the problem that the green screen cannot be degraded, and the technical research has not been reported in the field.
