Embodiment Construction

[0016] The present invention will be described in further detail below, so that those skilled in the art can implement it with reference to the text of the description.

[0017] The present invention provides a processing technology of polymer oil-absorbing paper, including:

[0018] Step (1) dissolving polylactic acid and poly-3-hydroxybutyrate caproate in an organic solvent to prepare the organic phase of a mixed solution of polylactic acid and poly-3-hydroxybutyrate caproate;

[0019] Step (2) dissolving ammonium bicarbonate in water to prepare the obtained water phase, the concentration of ammonium bicarbonate in the water phase is 4.3 ~ 6.7 g / L;

[0020] Step (3) Add natural fibers to the water phase. The length of the natural fibers is 30-50μm. The water phase is ultrasonically treated first. The frequency of ultrasonic treatment is 80-90KHz, and the time of ultrasonic treatment is 15-20min. The phases are divided into 4 to 7 parts and added to the water phase one by one. After ...

Abstract

The invention discloses a processing technology of polymer oil absorption paper. The processing technology comprises the steps that 1, an organic phase of the mixed solution of polylactic acid and 3-hydroxybutyrate caproate is prepared; 2, ammonium bicarbonate is dissolved in water to prepare a water phase; 3, natural fiber is added to the water phase, the length of the natural fiber is 30-50 microns, ultrasonic treatment is conducted on the water phase, the ultrasonic treatment frequency is 80-90 KHz, the ultrasonic treatment time is 15-20 minutes, then the organic phase is divided into 4-7 parts and is added to the water phase part by part, homogenizing treatment is performed after each part of organic phase is added, and emulsified liquid is obtained; 4, the emulsified liquid is put at normal temperature for 1-2 hours, then the temperature is reduced from the normal temperature to 5 DEG C, and standing continues at the temperature of 5 DEG C for 1 hour; 5, standing is performed at the temperature of 10-15 DEG C for 3-4 hours. The prepared oil absorption paper has good oil absorption capacity.

Description

Technical field [0001] The invention relates to a processing technique of polymer oil-absorbing paper. Background technique [0002] In cosmetic skin care, oil-absorbing paper or oil-absorbing film is an important facial care aid, mainly used to absorb and remove oily substances secreted by the human facial skin. The current oil-absorbing paper or oil-absorbing film has many disadvantages. For example, the powdery absorbent paper will fall off during storage and use; the natural fiber absorbent paper may damage delicate skin when used; the modified fiber absorbent paper may have chemical residues, which will be transferred during use. The affected area causes allergies. Therefore, there is a need for an oil-absorbing paper with more effective oil-absorbing capacity and no irritation to the skin. Summary of the invention [0003] The present invention designs and develops an oil-absorbing paper with better oil-absorbing capacity and no stimulating effect. [0004] The present inv...
