Embodiment 1

[0020] Nano antibacterial material preparation comprises the following steps:

[0021] Step 1. Add 12 parts of TiO to 50 parts of deionized water 2 / Sb 2 S 3 Composite antibacterial colloid, 4 parts of methacrylic acid hydroxypropyl sulfonic acid, 2 parts of acrylic resin and 3 parts of polyoxyethylene ether, ultrasonic dispersion for 15 minutes, ultrasonic frequency 4000W, to form a stable aqueous solution with a particle size of 6.8nm;

[0022] Step 2. Add 18 parts of methyl cyclomethacrylate, 12 parts of butyl acrylate and 2 parts of pop emulsifier in sequence to the above aqueous solution at a temperature of 55°C and a stirring speed of 70 rpm / min. After fully stirring and mixing, Stand at room temperature for 2h;

[0023] Step 3. Add 3 parts of tartaric acid and 2 parts of propylene glycol methyl ether acetate to the above-mentioned organic aqueous solution after standing for pre-stirring for 20 minutes, and the stirring speed is 4500 rpm / min to obtain a mixed slurry; ...

Embodiment 2

[0032] Step 1. Add 8 parts of TiO to 50 parts of deionized water 2 / Sb 2 S 3Composite antibacterial colloid, 3 parts of methacrylic acid hydroxypropyl sulfonic acid, 2 parts of acrylic resin and 3 parts of polyoxyethylene ether, ultrasonic dispersion for 15 minutes, ultrasonic frequency 4000W, to form a stable aqueous solution with a particle size of 6.8nm;

Abstract

The invention discloses a ventilating and sweat-discharging pointer. The ventilating and sweat-discharging pointer comprises a shell; an electric telescopic rod is fixedly arranged at the left end ofthe shell; a transparent crystal ball is fixedly arranged at the left end of the electric telescopic rod; a light-emitting diode is fixedly arranged in the transparent crystal ball; a fan switch is inlaid and arranged above the middle of the shell; a telescopic switch is inlaid and arranged above the shell on the right side of the fan switch; a light switch is inlaid and arranged above the shell on the right side of the telescopic switch; a page turning button is inlaid and arranged above the shell on the right side of the light switch; a plug is movably arranged at the right end of the shell;a hanging ring is fixedly arranged on the right side of the plug; a first motor is fixedly arranged at the left end of the internal part of the shell; a driving circuit board is fixedly arranged on the right side of the first motor; and a battery box is fixedly arranged on the right side of the driving circuit board. The ventilating and sweat-discharging pointer can ventilate and discharge sweat,avoids profuse sweating of a palm caused by the fact that the pointer is held for a long time, and has good use experience.

Description

technical field [0001] The invention relates to the field of pointers, in particular to a ventilation and perspiration pointer. Background technique [0002] The pointer is a stick used by teachers to indicate blackboard writing and pictures when they are giving lectures. It is a tool similar to a ruler used by teachers in the old days to punish and spur students. With the development of science, the pointer is also updated. The laser pointer came into being. The laser pointer is a radio frequency The page-turning laser pointer uses computer USB technology and radio technology, and integrates remote control computer functions and laser pointers. It is ideal for use with PCs or laptops and projectors, and is widely used in product demonstrations, audio-visual teaching and academic conferences. Tools for presentations. [0003] Existing pointers cannot ventilate and wick away sweat, and holding them for a long time will cause a lot of sweating in the palms of the hands, which...
