Medicament for treating acute soft tissue injury and its preparation process

Nano composite material of polystyrene-maleic anhydride/kaoline

The nanocomposite is that nanokaoline inorganic phase is dispersed in continuous phase of polystyrene-maleic anhdyride high polymer of which inorganic phase content is 1-30% of high polymer by weight. The preparing method includes dispersing maleic anhydride into solvent through kaoline modified by organic intercalation, adding it into styrene monomer containing free radical initiator, rising temperature to cause reaction for 2-4 hr. at 60-110 deg.C temperature, pouring it into precipitator for precipitation and obtaining product through washing and drying.

插层改性高岭土的制备方法

The invention relates to a method of preparing intercalation modified kaoline, firstly dispersing the kaoline in an intercalation agent solution to form uniform suspension serum, then making ultrasonic treatment, and finally separating, washing, drying and grinding to obtain the products, where the ultrasonic treatment: placing the suspension serum in a ultrasonic reactor, using 30-60 deg. water as medium, regulating ultrasonic frequency to 15-40 KHz, and making mixing ultrasonic treatment for 3-4 hours. It is a method of saving energy sources and benefiting environmental protection, and has high intercalation efficiency, the need time is short, on conditions of relaxative operation and environment, it can make the intercalation ratio up to above 90%.
