[0002] Since the birth of disposable vaginal dilators, manufacturers at home and abroad have used non-degradable plastics such as polystyrene or ABS to make them. Light weight, easy to carry, especially used to prevent cross-infection of diseases and other advantages, it is widely used. However, after more than 20 years of clinical practice, there are many problems in disposable vaginal dilators made of plastic: for example, there are reports of criminals Taking the opportunity to illegally recycle and reuse will leave hidden dangers for cross-infection of diseases, which will lead to the spread of vaginitis, cervicitis, sexually transmitted diseases, hepatitis B, AIDS and other diseases
But so far, there is no research and report on environmental protection, energy saving and degradable disposable vaginal dilators and their preparation methods at home and abroad.

Embodiment 1
[0034] Example 1 Injection molding method of environmental protection, energy saving and degradable disposable vaginal dilator:
[0035] Using the degradable base material of formula 1, its injection molding method is:
[0036] The first step, vacuum drying: the degradable substrate pellets of Formula 1 were vacuum-dried at 50° C. for 4 hours, and then used.
[0037] The second step, injection molding: Add the dried degradable substrate pellets of Formula 1 to the injection molding machine for injection molding. The barrel temperature is set as: feed inlet 160°C, compression section 165°C, metering section 170°C , nozzle 170°C;
[0038] Mold temperature: 25°C;
[0039] The injection pressure is: the first section is 75pa, the second section is 80Mpa, and the third section is 50Mpa;
[0040] Injection time: 4 seconds;
[0041] The holding time is: 0 seconds;
[0042] The screw speed is: 180 rpm.

Abstract
The invention provides an environmental-friendly and energy-saving degradable disposable vagina dilator and a preparation method thereof. A disposable vagina dilator is composed of an upper dilating slice and a lower dilating slice; all the members are made of a high-polymer main material capable of degrading base materials, a reinforcing agent, a lubricating agent and the like; the injection molding technique is as follows: a feeding opening is at 150-165 DEG C, a compression section is at 155-170 DEG C, a metering section is at 160-175 DEG C, and a nozzle is at 150-180 DEG C; the temperature of a mould is 10-40 DEG C; the injection pressure is 50-85 Mpa; the molding injection time is 4-5 seconds; the pressure maintaining time is 0 second; the rotary speed of a screw is 160-180 circles / minute. Every performance index of the obtained degradable disposable vagina dilator accords with the requirement of national industrial standard (YY0336-2002); after discarding, the disposable vagina dilator can be degraded to be H2O and CO2 by microorganisms under the natural condition without burning, and the environment cannot be polluted; thus the purpose of protecting environment and saving energy is achieved.
