preparation example Construction

[0013] The invention provides a method for preparing a brake handle sheath of a high-toughness health-care wheelchair, comprising:

[0014] 1) Polyurethane resin, polyvinyl chloride resin, poe elastic toughening agent, ceramic fiber, glass fiber, bamboo charcoal fiber, tricresyl phosphate, dioctyl phthalate, glycerin, turpentine and silane with the brand KH550 After the coupling agent is mixed, the first kneading is carried out to obtain the mixture M1;

[0015] 2) adding titanium oxide, antistatic agent, light protein shale powder and silver nanoparticles into the mixture M1 and performing a second kneading to prepare a mixture M2;

[0016] 3) The mixture M2 is extruded and processed to obtain the high-toughness healthcare wheelchair brake handle sheath.

[0017] In the above technical scheme, the specific dosage ratio of each raw material in each step can be selected within a wide range, but in order to improve the mutual synergy between each raw material, preferably, in te...

Abstract

The invention discloses a high toughness health care wheelchair brake handle sheath and a preparation method thereof. The preparation method comprises the steps of: 1) mixing polyurethane resin, polyvinyl chloride resin, a poe elastic toughening agent, ceramic fiber, glass fiber, bamboo charcoal fiber, tricresyl phosphate, dioctyl phthalate, glycerol, turpentine and a silane coupling agent with a mark of KH550, and then performing first kneading to obtain a mixture M1; 2) adding titanium oxide, an antistatic agent, light protein shale powder and silver nanoparticles into the mixture M1 and conducting second kneading to obtain a mixture M2; and 3) carrying out extrusion molding and processing on the mixture M2 so as to obtain the high toughness health care wheelchair brake handle sheath. The high toughness health care wheelchair brake handle sheath has high strength, good toughness and other excellent mechanical properties, also has health care and antibacterial functions, further ensures the wheelchair users' physical and mental health, and improves the wheelchair use comfort.

Description

technical field [0001] The invention relates to the fields of medical and health care equipment, in particular to a high-toughness health-care wheelchair brake handle sheath and a preparation method thereof. Background technique [0002] Wheelchair is an important tool for rehabilitation. It is not only a means of transportation for physically disabled and handicapped people, but more importantly, it enables them to perform physical exercises and participate in social activities with the help of wheelchairs. Ordinary wheelchairs are generally composed of four parts: wheelchair frame, wheels, brake device and seat. [0003] When the user uses the wheelchair alone, the operation performance of the brake directly affects the adaptability and comfort of the user; in addition, most wheelchair users are patients or injured with weak resistance, so the brake handle of the wheelchair Softness, slip resistance and its antimicrobial properties all affect wheelchair user fit and com...
