Description

A kind of high preparation method for receiving dirty cleaning sponge
Technical field
The invention discloses a kind of high preparation method for receiving dirty cleaning sponge, belong to cleaning sponge preparing technical field.
Background technology
It is continuous that cleaning sponge is called continuous superstrong pollution-removing bubble, magic sponge and nanometer.Cleaning sponge can effectively clean accumulation Tea stain, dirt, incrustation scale, soap scum, oil stain, to hard smooth surface (such as ceramics, minute surface, glass, stainless steel), can more play good Clean effect.Cleaning sponge need to only use water, be not required to cleaning agent, superstrong pollution-removing is time saving, laborsaving, and convenient, gently wiping can just go Except spot.The maximum difference of high density cleaning sponge and traditional cleaning mode, the product uses the mechanism of physical technology of removing pollution, by sea Nanotube capillaries open-celled structure in silk floss, is smearing the old dirt of wiping process automatic absorbing material surface, as countless superpower micro- Type dust catcher only needs clear water, just can easily remove dirt without cleaning agent in work.
The chemical composition of the traditional sponge now used in daily life, which is mainly polyurethane, polyester and polyvinyl alcohol etc., to be had Machine synthesizes macromolecule.Although such synthesis macromolecule sponge product production technology oneself through quite ripe, the drawbacks of also having obvious, As resource and energy resource consumption are big；Discarded sponge degraded is difficult, and recycling is poor, severe contamination environment etc..In current stone The reserves decline of oil and coal, problem of environmental pollution increasingly highlight and people the enhanced situation of environmental consciousness and health perception Under, the development of such sponge receives certain limitation.
It is being the scientific research field advocated with " environment-friendly material ", biodegradable native cellulose is used as a kind of green Resource has caused the extensive concern of people.Cellulose is natural resources most abundant on the earth, with good biology drop Xie Xing, and renewable, cycle period is short, is " inexhaustible ".Compared with traditional sponge, cellulose sponge Possess following characteristics：1. good hydrophilic property；2. absorption speed is fast, and soil pick-up ability is strong；3. easily air-dry；4. discarded object is easily by biology drop Solution, the product after degraded is environmentally safe.As can be seen here, preparing biodegradable sponge has good use value and ecology Benefit.
The content of the invention
Present invention mainly solves technical problem：Serious for existing traditional sponge pollution environment, degraded is difficult, reclaims It is poor to recycle, and the limited defect of pollutant carrying capacity is there is provided a kind of high preparation method for receiving dirty cleaning sponge, of the invention first by silicon The material mixings such as diatomaceous earth, cornstarch obtain mixed-powder after crushing, and fiber dust are being collected to obtain from black liquid, then take foaming Agent is soaked in a solvent, is vacuumized after heating, is added after vacuumizing and progress foaming processing in mould is poured into after fiber dust, mixing Sponge is obtained, finally takes Tea Saponin and APG to add above-mentioned sponge after adding in deionized water, is extruded after absorption, after extruding Sponge, which is added in fatty enzyme aqueous solution, to be soaked, and is added crosslinking agent, is freeze-dried after addition, you can is obtained height and is received dirty cleaning sea Silk floss, the cleaning sponge pollutant carrying capacity for preparing of the present invention is strong, and infiltration rate is fast, using being easily biodegradable after discarded, and Product after degraded is environmentally safe.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
