The invention relates to a high-activity multifunctional laundry bead and a preparation method thereof, and belongs to the technical field of daily chemical detergents. The laundry bead is prepared from dodecyl benzene sulfonate, dodecyl benzene sulfonic acid monoethanol amine salt, oleic acid monoethanol amide polyoxyethylene ether, fatty acid methyl ester ethoxylate, amine oxide, an organic silicon compound, deionized water, propylene glycol, an re-deposition resistant agent, triisopropanol amine, an anti-cross-color agent, a bacteriostatic agent, a compound enzyme, a water softener, a fluorescent whitening agent, a preservative, citric acid, essence and perfume. The raw materials are uniformly mixed and stirred, the pH is adjusted, then discharging is carried out, and finally packagingis performed to obtain the laundry bead. By adding a little amount of solvent and the dissolving property of a nonionic surfactant, the active matter content of the laundry bead can reach 80% and is 3-4 times higher than that of a traditional detergent in the market.

The invention relates to a degradable capacitor plastic shell which is composed of the following components in parts by weight: 35 parts of polyvinyl alcohol resin, 15 parts of gelatin, 10 parts of methyl-silicone rubber, 5 parts of hyaluronic acid, 5 parts of tribasic lead sulfate, 5 parts of nano silicon dioxide, 5 parts of modified wood-plastic powder, 2 parts of chlorinated paraffin, 2 parts of propanediol, 2 parts of palm oil, 5 parts of carbon fiber, 5 parts of metallocene polyethylene, 2 parts of methylsilicone oil, 0.5 part of tobacco cellulose, 2 parts of plasticizer, 2 parts of oxidized polyethylene, 2 parts of dioctyl adipate, 2 parts of rare-earth light conversion agent, 2 parts of cotton fiber, 2 parts of corn starch, 2 parts of polyester rubber powder, 2 parts of butyl acetate and 2 parts of talcum powder. The method has the advantages of simple components and low cost; the finished product is degradable, has stable performance, and does not have toxicity or harm in a high-temperature environment; and meanwhile, by changing the traditional preparation technique and adding the refrigeration procedure, the product has higher safety and still has favorable stability at higher temperature.

The invention relates to the field of chemical materials, in particular to wheatstrawplant fibersynthetic resin and a preparation process thereof. The wheatstrawplant fibersynthetic resin is prepared from the following raw materials: wheat-straw powder, Chinese insect wax, agar, terephthalic acid, potato starch, propanediol, balsam powder,poly-hydroxy butyrateand polylactic acid fiber. The preparation process comprises the following steps of (1) preparing fine particlewheat straw powder; (2) preparing a primary mixed material; (3) preparing wheat straw fiber powder; (4) preparing a mixed adding material; (5) uniformly stirring the mixed adding material and the polylactic acid fiber; then, performing blending extrusion and injection moulding; obtaining the wheat straw plant fiber synthetic resin. In order to avoid the waste of resources such as crop waste materials, the crop waste materials are fully utilized; the environment pollution is reduced; the production cost is low; the application is very wide; the rural resource advantage can be realized; an effective method and path areprovided for reasonable utilization of waste crops.
