Description
Technical field
The present invention relates to a kind of elastomeric material and preparation method thereof, be specifically related to a kind of water swelling rubber material and preparation method thereof.
Background technology
Water swelling rubber is as a kind of watertight rubber material, and its great advantage is exactly have excellent sealing leak stopping function.Obtain at construction fields such as hydro project subway tunnel, underground foundation work dams at present and applied widely.
As everyone knows, on the whole, rubber is a kind of hydrophobic material, in its molecular chain except carbon, hydrogen segment, also containing a small amount of hydrophilic radical.Upon contact with water, by diffusion, knitting wool, the physical action such as thin and surface adsorption enters in rubber bodies water molecules, makes rubber rapid spatial expansion.Meanwhile, the hydrophilic radical of water molecules in rubber bodies is combined, and forms a kind of avidity.Like this, the water entered in rubber bodies makes hydrophilic radical dissolve or expands, inside and outside rubber bodies, form permeable pressure head.This pressure reduction also has promoter action to water to the infiltration in rubber bodies.Hydrophilic radical absorbs moisture continuously, makes rubber expand deformation.When anti deformational force is suitable with permeable pressure head, just reach balance, water-swelling effect can keep relative stability.
The performance of water swelling rubber has not only depended on formula and the component of material, has also depended on the preparation technology of material.Poor compatibility in existing water swelling rubber between rubber and resin, the cross-linking density of rubber is higher, and sealing performance is not good.
