Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
At present, the method for manufacturing the silicone rubber urethral catheterization sleeve is generally a dipping forming method, a certain amount of solvent is required to be added for diluting and adjusting the viscosity of liquid silicone rubber, and in order to enable the urethral catheterization sleeve product to be in accordance with biocompatibility, the solvent and micromolecules in the silicone rubber are required to be fully volatilized by vulcanization at the temperature of 170-200 ℃ for more than 1 hour. The pressure sensitive adhesive used in US patent 07876702 is an acrylic pressure sensitive adhesive which is difficult to withstand high temperature vulcanization for a long time.
Examples
As shown in fig. 1 and 2, a method for manufacturing a self-adhesive male urisheath, one end of the urisheath is a glans penis sheath, which is integrally connected with a penis sheath, comprising: s1, sizing and curing: firstly, the whole mould is immersed into the silicon rubber solution, and then the mould is taken out to solidify the silicon rubber sleeve for 3-20min at the temperature of 100-. Further, the curing temperature of the silicon rubber sleeve in S1 is 120-150 ℃, and the curing time is 5-10 min. S2, sizing, curing and vulcanizing: immersing the glans penis urine tube sleeve of the mold into the silicon rubber solution, taking out the mold, curing the silicon rubber sleeve for 3-20min at the temperature of 100-plus-one 200 ℃, and then vulcanizing the silicon rubber sleeve for 0.2-4h at the temperature of 170-plus-one 220 ℃. If the curing temperature of the silicone rubber sleeve is too low in the first two times, the curing time is prolonged, and if the curing temperature is too low, the curing is extremely slow, so that the working efficiency is reduced; when the temperature is too high, the thickness of the silica gel film is not easy to control, and obvious flow lines appear on the silica gel at the transition part of the shape of the die, so that the reject ratio of the product is improved. S3, coating, curing, gluing and curing: firstly coating a release agent on the outer surface of the condom of the silicone rubber sheath, then curing the release agent for 5-10min at the temperature of 120-. Further, the curing temperature of the adhesive material in S3 is 110-150 ℃, and the curing time is 1-5 min. The curing temperature of the adhesive material is low, the curing time is prolonged, and the crosslinking reaction is slow; when the curing temperature is too high, the adhesive material is liable to age and turn yellow. S4, bonding the finished product: the self-adhesive male urethral catheterization sleeve comprises a urethral catheterization sleeve 1, a release agent layer 2 and an adhesive material layer 3, wherein the release agent layer 2 is attached to the outer surface of the urethral catheterization sleeve 1, the adhesive material layer 3 is attached to the release agent layer 2, and the adhesive material layer 3 is an acrylic pressure-sensitive adhesive layer or a coupling agent-treated acrylic pressure-sensitive adhesive layer.
The embodiment adopts a vulcanization process, and the urethral catheterization sleeve has no volatile substances; adding a coupling agent with binding capacity to pressure-sensitive adhesive and silicon rubber into the acrylic pressure-sensitive adhesive to increase the bonding strength of the pressure-sensitive adhesive to the silicon rubber; the release agent is coated on the outer surface of the urine sleeve, so that the pressure-sensitive adhesive has a good release effect on the outer surface, and the urine sleeve is easy to unfold when in use.
Although embodiments of the present invention have been described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
