Description
Technical field
The invention belongs to gel preparation technical fields, and in particular to a kind of silicone gel.
Background technique
Dimethyl silicone polymer is also known as dimeticone, and greasy property is good, can form one layer of uniform tool after applying skin
There is the protective film of waterproofness, but it is good without any viscosity and greasy feeling, glossiness.And the performance of ultra-violet radiation resisting
It is good: it under ultraviolet light will not oxidation deterioration and cause to skin irritation.Antistatic property is good: experiments have shown that, nuzzle up and contains
The skin electrostatic of polysiloxanes face cream is all eliminated, and has apparent dust-proof effect.Good permeability: even if being formed on the skin
Silicone film nor affects on sweat discharge.It is nontoxic, odorless, tasteless, stimulation and allergy will not be caused to skin, it is highly-safe, it fits
When use, can promote local blood circulation, improve scar tissue metabolism and nutrition supply, inhibit fibroblast in scar tissue
Hyperplasia.
Hydrogel is a kind of tridimensional network rubbery polymeric substrate matter with strong water absorbing capacity, and water content is high, machine
Tool performance is good, superior biocompatibility, and more application is in the industries such as medical treatment, cosmetics, environmental protection at present.Go out currently on the market
Existing silicon hydrogel product, such as pressing down the silicone gel dressing of scar.But dimethyl silicone polymer is oily matter, to system
It at aqua gel, needs to match out suitable emulsifier and process conditions, can just be made.And match needed for product currently on the market
Side needs to add the ingredients such as surfactant just mostly can be such that made finished product reaches compared with stable state, such as the environment temperature temperature difference
Excessive or placement excessive cycle still will appear the wild effects such as layering, and the coordinative composition of equipments technique fabrication cycle used is long, at
This is higher, still needs to be further improved.
Summary of the invention
The object of the invention is that providing a kind of silicone gel to solve the deficiencies in the prior art, it is without the use of surface
Activating agent, and preparation method is simple, and finished product is more stable.
The purpose of the present invention is what is realized with following technical proposals:
A kind of silicone gel, it is prepared by the raw material of following parts by weight: dimethyl silicone polymer 20-30, Pemulen
TR-1 NF polymer 0.3-0.5, glycerol 6-10, propylene glycol 5-8, water 30-70.
The dimethyl silicone polymer viscosity is 50-500cst.
It further, further include bacteriostatic agent in the silicone gel.
The preparation method of silicone gel as described above, comprising the following steps:
(1) Pemulen TR-1 NF polymer is dissolved in suitable quantity of water, places 8-16h, is swollen it sufficiently；
(2) dimethyl silicone polymer, glycerol and propylene glycol are then added during being stirred continuously, continues stirring until gel
Then shape adds water to full dose, stir evenly to get.
Silicone gel provided by the invention only need to use Pemulen TR-1 NF polymer as emulsifier, then add
Add suitable glycerol and propylene glycol auxiliary material, can prepare viscosity by simple process is suitable for that quality is fine and smooth, and what is tended to smear out is solidifying
Glue, and stability is strong, has good heat-resisting cold resistance, can be used for wound dressing, dispel scar etc..
