Abstract
The invention relates to a preparation method of a stabilizer of a building material, in particular to a stabilizer for improving the asphalt stability and a preparation method thereof. The preparation method of the asphalt stabilizer comprises the following steps of: adding sulfur of corresponding weight parts to a high-speed disperser; then, adding polyethylene glycol, calcium chloride, ethylene-vinyl acetate copolymer and polyoxymethylene of corresponding weight parts, and premixing for 10-30 min; adding the mixture to a grinder to grind so that the grain size is smaller than 100-200 meshes; and adding the ground premix to water and a foam suppressor with the weight parts and then shearing at a high speed for 10-20 min so as to uniformly mix the premix. The preparation method of the invention simplifies the preparation method of the asphalt stabilizer, decreases the cost of the preparation process and lightens the labor intensity of workers.

In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions:
A kind of preparation method of pitch stablizer, it is to count ratio by following raw materials in parts by weight to be prepared from: polyoxyethylene glycol 10-20 part, 5～10 parts in sulphur, calcium chloride 10-20 part, defoamer 2-4 part, ethylene-vinyl acetate copolymer 15-30 part, polyoxyethylene 5-15 part, water 20-40 part; In high speed dispersor, add the sulphur that meets described parts by weight, carried out premix 10-30 minute to wherein adding the polyoxyethylene glycol, calcium chloride, ethylene-vinyl acetate copolymer and the polyoxyethylene that meet described parts by weight again; Mixture is added in the shredder, grind, make its particle diameter less than the 100-200 order; Pre-composition after grinding is added water and the defoamer that meets described parts by weight, high speed shear 10-20 minute again, pre-composition is mixed promptly.
Described doing time in advance is 15 minutes.
Described shear time is 15 minutes.
The grain size of described grinding is 100 orders.
Advantage of the present invention and effect are as follows:
The present invention makes the pitch stablizer after adopting polyoxyethylene glycol, sulphur, calcium chloride, defoamer, ethylene-vinyl acetate copolymer, polyoxyethylene and water to mix, through a large amount of verification experimental verifications, effectively raise the bituminous stability after in plain asphalt, adding product of the present invention, preparation method of the present invention simplifies the preparation method of pitch stablizer, reduce the cost of preparation process, reduce working strength of workers.
