Present invention also offers the preparation method of above-mentioned steel bead wire top coat liquid, comprise the steps:
(1) toluene, acetone are mixed with mixed organic solvents in proportion;
(2) methyl methacrylate rubber pulverizes the rubber grain for diameter 3-5mm, joins in mixed organic solvents, soaks and within 24 hours, makes methyl methacrylate rubber become fully dissolving, use strainer filtering to fall insoluble composition;
(3) in the mixed organic solvents being dissolved with methyl methacrylate rubber, liquid polysulphide rubber, coumarone indene resin, terpine resin, additional crosslinker PDM is added, stir at normal temperatures and make solute dissolves, then insoluble composition is fallen with strainer filtering, obtained steel bead wire coating solution.
Use methyl methacrylate rubber in steel bead wire top coat liquid provided by the invention, can form one deck rubber film on steel bead wire surface, methyl methacrylate rubber is the multipolymer of natural rubber and methacrylic acid rubber, all has good adhesive effect to rubber and metal.
Add liquid polysulphide rubber in coating solution, strengthen the bounding force of steel bead wire and rubber, after liquid polysulphide rubber sulfuration, there is excellent ageing-resistant performance.
Add coumarone indene resin in coating solution, have the effect of plasticising and thickening, coumarone indene resin also has certain rust inhibition.
Add terpine resin in coating solution, strengthen the bond properties of steel bead wire and rubber, terpine resin also has excellent anti-oxidant and thermostability.
Add additional crosslinker PDM in coating solution, in steel bead wire and vulcanization of rubber adhesion process, PDM can cross-linked rubber, enhancing adhesive strength.
In coating solution, rubber and resin Composition form the coating film of certain thickness rubber and plastic compound jointly on steel bead wire surface, and this layer film plays the effect of isolated moisture in air and oxygen to a certain extent, plays certain rust inhibition.
According to the dissolution characteristics of solute, use toluene, acetone as solvent.
At the uniform antirust coating of copper facing steel bead wire surface-coated one deck, effectively isolated air and moisture, play steel bead wire antirust.At the uniform tackifier coating of copper facing steel bead wire surface-coated one deck, the bond properties of steel bead wire and rubber can be improved.
