The proportion of polysiloxanes synthesis material, anti-corrosion effect are substantially reduced, and illustrate methyl hydrogen dichlorosilane and methyl divinyl silane
Dosage is very big to the compound influence of polysiloxane structure；Reference examples 9 and example 10, increase modifying agent ethylene oxide and propylene oxide
Dosage, effect is still bad, illustrates modifying agent excessively and will affect the anti-corrosive properties of coating；Therefore rubber prepared by the present invention is used
Gloves have good anticorrosion ability.
