The chemical structure of the silicone resin is between inorganic and organic -- 2017-09-22

Structure silicone resinThe chemical structure of the siliconeresin is between inorganic and organic molecular structure of quartz as areference, a main chain composed of silicon and oxygen atoms, therefore all thesilicone resin other than silicone having more inorganic properties. After 1009silicone combustion, the remaining approximately 909 silica, which is asilicone resin paint with superior weather resistance provide a guaranteestructure. Silicone resin structures different from that of qua ...

Physicochemical properties of polydimethylsiloxane -- 2017-09-21

Polydimethylsiloxane chemical state Dimethyl silicone oil, colorless or light yellow liquid, tasteless, high transparency, with heat resistance, cold resistance, viscosity changes with temperature, water resistance, surface tension is small, with thermal conductivity Sex, thermal conductivity of 0.134-0.159W / M * K, translucent light transmittance of 100%, dimethyl silicone oil non-toxic and tasteless, with physiological inertia, good chemical stability. Electrical insulation and weather resist ...

Control of reaction conditions for the preparation of fine silicone resin powder -- 2017-09-20

Application performance silicone resinUse the plus silicone resin powderconditioner treated hair, dry hair, wet combing has been effectively improved.Description silicone resin powder lubrication, excellent dispersion, can reducethe dry, wet hair and comb friction, providing smooth feel to hair. However,the effect of improving the silicone resin powder prepared under differentconditions the hair combing difference is not a small difference. Therefore,control of the reaction conditions for prepar ...

Polydimethylsiloxane -- 2017-09-19

Polydimethylsiloxane, also known as dimethyl silicone oil, is a hydrophobic silicone material. In the pharmaceutical, daily chemicals, food, construction and other fields have applied, it has reached hundreds of derivatives, commonly used polysiloxanes are: polydimethylsiloxane, cyclomethicone , Aminosiloxanes, polymethylphenylsiloxanes, polyether polysiloxane copolymers. Which cyclodimethylsiloxane is a commonly used polysiloxane.

Preparation of silicone resin microspheres -- 2017-09-18

Synthesis of silicone resinFirst, we hydrolysis - polycondensationstep method, methyltrimethoxysilane as raw materials, the preparation of asilicone resin microballoons. From the two-step hydrolysis and condensationreaction mechanism of the reaction system PH value, oil-water ratio, whetherthe stirring conditions hydrolysis and condensation reactions affect thedistribution and size of the microspheres was studied. Experimental resultsshow that:1. methyltrimethoxysilane hydrolysis, PHvalue is bet ...

Better than hydrolysis polycondensation method -- 2017-09-15

Silicone resin powder and silicone resinemulsionAfter using a silicone resin powder addedto the treatment of hair conditioner, hair dry, wet combing has beeneffectively improved. Description silicone resin powder lubrication, excellentdispersion, can reduce the dry, wet hair and comb friction, providing smoothfeel to hair. However, the effect of improving the silicone resin powderprepared under different conditions the hair combing difference is not a smalldifference. So good silicone resin powd ...

Conditioning soaking agent mostly silicone oil-based silicone material -- 2017-09-14

The role of silicone oil in shampoo andhair care productsFrom the consumer's point of view, combingthe hair test is an important indicator of hair care products care benefits. Itmeans that when the size of the comb through the hair resistance encountered.It is not only the diameter, stiffness, curl, length, humidity and combmaterial, density and size of the properties and other factors related to hair.Also with the use of hair care products after flowing through the resistance,smoothness and moi ...

Improve the stability of the emulsion polymerization process -- 2017-09-13

The mass ratio of emulsifier on emulsionstability Add nonionic emulsifiers with a longpolyoxyethylene chain in the anionic emulsion, it helps to increase therelative stability of the silicone resin emulsion. This is because in line withthe use of two emulsifiers in the emulsion polymerization process arealternately adsorbed on the surface of the latex particles. This will not onlyput on the latex particles from the particle surface emulsifier widening, andelectrostatic shielding effect of n ...

Development of emulsion polymerization technology -- 2017-09-12

Prepared by emulsion polymerization ofsilicone resin emulsionEmulsion polymerization process is a veryimportant, since the beginning of research has been 90 years of history.Because of its simple process operation, pollution is small, can be widelyapplied. Now the world's synthetic polymer product by this process tens ofmillions of tons of production.The basic components of the emulsion arewater, monomers, emulsifier and initiator, the polymerization reaction systemis a non-homogeneous, heteroge ...

Methyltrimethoxysilane is effectively hydrolyzed -- 2017-09-11

Methyl trimethoxysilane as raw material,prepared by a two-step hydrolysis and condensation of spherical silicone resin.1. In the hydrolysis ofmethyltrimethoxysilane, PH value is between 3.0 to 6.0, the hydrolysis reactionmixture as a clear transparent, free floating oil stratification. Descriptionof methyltrimethoxysilane were effective hydrolysis reaction, to give methylsilanol.2. In the silanol condensation reactionprocess, the control range of PH value is between 8.0 and 10.0, in order toobta ...
