Abstract
Urea formaldehyde resin emulsified asphalt is formed by combining 40-60 parts of emulsified asphalt, 2-8 parts of a urea formaldehyde resin emulsion, 1-3 parts of a cationic emulsifier, and 100-150 parts of water. The asphalt emulsion comprises 100 parts of asphalt, 1-3 parts of sodium alkyl benzene sulfonate, 3-8 parts of polyvinyl alcohol, 1-2 parts of caustic soda, and 40-80 parts of water. Asphalt, sodium alkyl benzene sulfonate, polyvinyl alcohol, caustic soda and water are mixed, and stirring emulsification is carried out for 60 to 90 minutes at the temperature of 100-150 DEG C to obtain the asphalt emulsion; and 40-60 parts of the emulsified asphalt, 2-8 parts of the urea formaldehyde resin emulsion, 1-3 parts of the cationic emulsifier and 100-150 parts of water are mixed to obtain the product. The product has the advantages of easily obtained raw materials, low cost, green environmental protection, convenient use, and good effect.
Description
Technical field
The invention belongs to a kind of pitch and utilize technology.
Background technology
Emulsified bitumen be pitch and emulsifying agent under certain process acts, generate the liquid bitumen of oil-in-water or water-in-oil (specifically who wraps the kind who will see emulsifying agent).Emulsified bitumen is by the road bitumen of common applied at elevated temperature, through mechanical stirring and chemically stable method (emulsification), is diffused in water and is liquefied as under normal temperature that viscosity is very low, the good a kind of pavement construction material of mobility.Can use by normal temperature, and can use together with moist building stones with cold.Emulsified bitumen is divided into cationic emulsified bitumen, anionic emulsified bitumen and non ionic emulsified bitumen.The bitumen particle of cationic emulsified bitumen is positively charged, and anionic emulsified bitumen particulate is electronegative.When cationic emulsified bitumen contacts with aggregate surface, due to electrically charged difference, there is a natural attraction between the sexes in generation, and both can make bitumen particle wrap at aggregate surface in the situation that having moisture film, still can fine absorption combination.Thereby (more than 5 ℃) still can construct under dark and damp, low temperature condition.But anionic emulsified bitumen is just in time contrary, it and moist aggregate surface are all electronegative, make it produce two like magnetic poles repel each other, bitumen particle can not stick on aggregate surface very soon, if bitumen particle is wrapped at aggregate surface, must be after moisture evaporation in emulsion, so be just difficult to construction while meeting dark and damp or low temperature season.When emulsified bitumen breakdown of emulsion solidifies--be reduced to continuous pitch and moisture and exclude completely, the final strength of pavement material could form.Modified emulsifying asphalt is pitch and emulsifying agent, with latex under certain process acts, the liquid bitumen of generation.Modified emulsifying asphalt and emulsified bitumen are just different from while generating and add and do not add latex.Bitumen particle is dispersed in resulting stable emulsion in the aqueous solution that contains emulsifying agent.
Through Chinese publication retrieval, do not find the scheme identical with present patent application.
Summary of the invention:
The object of the invention is to; A kind of urea-formaldehyde resin emulsified bitumen is proposed.
Urea-formaldehyde resin emulsified bitumen of the present invention, is characterized in that: by weight, by emulsified bitumen 40-60 part, urea-formaldehyde resin emulsion 2-8 part, cationic emulsifier 1-3 part, water 100-150 part constitutes; Colas: by 100 parts of pitches, sodium alkyl benzene sulfonate 1-3 part, polyvinyl alcohol 3-8 part, caustic soda 1-2 part, water 40-80 part forms, and pitch, sodium alkyl benzene sulfonate, polyvinyl alcohol, caustic soda, water is mixed, at 100-150 ℃, within stirring and emulsifying 60-90 minute, obtain colas, get emulsified bitumen 40-60 part, urea-formaldehyde resin emulsion 2-8 part, cationic emulsifier 1-3 part, water 100-150 part is mixed, and obtains product.
The present invention compared with prior art its beneficial effect is: have raw material and be easy to get, cost is low, and environmental protection is easy to use, effective advantage.
