Abstract
The present invention utilizes the resulting liquid phase by product of chlorohydrination production propylene oxide process to make bituminous composition for organic solvent, and it consists of (weight %):
10-50 pitch
0-20 properties-correcting agent
The 0-20 weighting agent
The equal amount organic solvent
Description
The invention belongs to the bituminous composition field.
The solvent-borne type bituminous composition is by solvent evaporates and dry and hard film forming.Therefore, in bituminous composition, be very important to choice of Solvent.It is related to the formation of filming, and influences the quality and the cost of coating.The solvent of bituminous composition generally adopts aliphatic hydrocarbon (as gasoline, hexanaphthene, normal heptane etc.) or aromatic hydrocarbon (as benzene,toluene,xylene etc.).These materials all are important Organic Chemicals, and price is more expensive.
Task of the present invention is exactly to seek the bituminous composition solvent that a kind of solubility property is good, evaporation rate is moderate, cheap and easy to get.
The liquid phase by product that chlorohydrination production propylene oxide process is produced is a kind of mixture.Its main component is propylene dichloride and dichloroisopropyl ether, and total content is greater than 90 percent.Up to now, these by products do not obtain reasonable use as yet, make it become the burden that chlorohydrination is produced this technology of propylene oxide.The present invention utilizes propylene dichloride and dichloroisopropyl ether that pitch, rubber and resin are had good solubility energy and the moderate characteristics of evaporation rate, made with pitch be base-material, with rubber or resin be properties-correcting agent, be weighting agent with the mineral substance, with the mixture of propylene dichloride and dichloroisopropyl ether or propylene dichloride or dichloroisopropyl ether bituminous composition as organic solvent.This bituminous composition contains (weight %):
10-50 pitch
0-20 properties-correcting agent
The 0-20 weighting agent
The equal amount organic solvent
The organic solvent that is adopted in the above-mentioned prescription is mixture or propylene dichloride or the dichloroisopropyl ether that mainly contains propylene dichloride, dichloroisopropyl ether.The properties-correcting agent that is adopted in the prescription is rubber (as natural rubber, chloroprene rubber, styrene-butadiene rubber(SBR), isoprene-isobutylene rubber, regenerated rubber etc.), or resin (as polystyrene, resol etc.).In order to further specify problem, introduce the preparation method below:
Pitch, rubber (or resin) are crushed to the fragment of diameter below 15 millimeters, in stirring tank with the liquid phase by product (mixture or propylene dichloride or the dichloroisopropyl ether that mainly contain propylene dichloride, dichloroisopropyl ether) of chlorohydrination production propylene oxide process with rubber (or resin) stirring and dissolving 24 hours at normal temperatures, after treating the rubber dissolving, add pitch again, continue to stir at normal temperatures tinning sealing after 24 hours, the bituminous composition product.

The technical feature of the bituminous composition that example one is made according to the present invention is:
Viscosity (being coated with cup No. 4) 93 seconds
Freeze-thaw-test: after freezing four hours, at room temperature soak four under negative 20 ℃
Hour, repeat 25 times and do not split.
Cohesive force:＞2.2 kilograms per centimeter
2
Thermotolerance: 80 ℃ did not trickle in eight hours, 110 ℃ three hours not
Trickling.
Water-permeable: 2 kilograms per centimeter
2Pressure is above waterproof following half an hour.
Splitting resistance: when 6 millimeters cracks appear in test specimen plate face, film and do not split.
Resistance to acids and bases: soaked in 22 days the back do not have peel off, foaming, layering, wrinkling
Phenomenon.
More than these performances all above state-set standard.
The present invention has opened up an approach of making asphalt paint take the liquid phase accessory substance of chlorohydrination production propylene oxide process as solvent. This liquid phase accessory substance is the solvent that a kind of solubility property is good, evaporation rate is moderate, cheap and easy to get. According to the solvent load difference, it can be used as asphalt adhesive, pitch joint seal ointment or water-repellent paint, does not add the product of modifier and filler, is the adhesive bitument primer that construction is used. The present invention compares with other organic solvent type asphalt paints, and not only production technology is simple, and asphalt paint quality height the more important thing is that the production cost that can make coating reduces about 40%, has significant economic benefit. In addition, also make the liquid phase accessory substance of chlorohydrination production propylene oxide process find the approach of reasonable utilization, the change refuse is useful paint solvent, has obvious social benefit.
