Abstract
The viscosity of the asphalt emulsion is controlled by adding up to 1% by weight of a modified starch consisting of up to 27% amylose and the remainder amylopectin.
Description
The present invention introduces the modification of relevant bituminous modification, particularly colas, so that it meets the standard of American Society Testing and Materials (ASTM) to the regulation of Sai Bote (Saybolt) viscosity of various rank bitumen emulsions.Pitch one speech that this standard specifications adopted had both comprised the pitch in naturally occurring pitch such as Te Linida (Trinidad) lake, comprised the synthetic asphalts of producing in the petroleum refinery again.
Before Holy Bible period, pitch by people as material of construction, said exceedingly high tower in the Holy Bible, when it is built in the mortar employed Gomorrah foundry loam be exactly pitch.Recently, the joint cement during pitch has been used to build the road.Colas also is widely used in building and the maintenance road surface.A current problem that runs into is too strong and energy and a Segregation of colas flowability heat or warm.If when especially colas was with the modification of a kind of synthetic polymer emulsion institute, this situation was even more serious.At least since the nineteen thirty, people have known and adopt synthetic polymer to come pitch is carried out modification.Have some textbooks that bituminous has been discussed and use and modification, comprising " pitch and their allied substances " arranged, the 5th edition, the special. A Baila Durham of Haber (Herbert Abraham) is write Van Nostrand press; " pitch science and technology ", Yi Te Wien .J. crust thatch (Edwin, J, Barth) is write Gordon and Breach press; " pitch and road-making material, modern technologies ", John .E. Bai Erxun (John E.Parson) writes, Noyes data company, 1977; And " basic asphalt emulsion handbook pitch No. the 19th, handbook book series of association (MS-19), publish in March, 1979.
The applicant can find has only a kind of patent that the use of various natural thickeners in bitumen emulsion has been discussed in the patent.
No. the 437th, 674, English Patent, deliver this patent with the name of E.I.Du Pont de Nemours and Company November 4 nineteen thirty-five, announced a kind of invention of dispersion agent of pitch aqueous emulsions.This dispersion agent is a kind of alkali (comprising ammonium) or alkaline earth element and a kind of salt that alkylsurfuric acid generated that contains at least 8 carbon atom alkyl groups.Also openly stated simultaneously " included thickening material has for example casein, egg white, binding agent in the emulsion, gelatin, resin or various starch, tannin, natural gum, dextrin and tapioca (flour), flour ...." representative positively charged ion rapid hardening emulsion, its pH value is about about 3.The pH value of conventional anionic emulsion is about about 12.Usually, unmodified starch at pH less than 5 or can in than the short period, degrade greater than 10 o'clock.
Current, there is not doping behind a kind of ideal, can join this additive subsequently in the existing bitumen emulsion, produce viscosity, keep viscosity.Usually, if a kind of viscosity of bitumen emulsion is too low, can be with this emulsion and a kind of emulsion fusion, to increase the viscosity of bitumen emulsion with viscosity higher.
The invention provides a kind of adjusting bitumen emulsion method of viscosity, its pH value of the bitumen emulsion of being regulated can reach 10,122 °F down its viscosity numbers reached for 75 plug baud seconds at least.Adding weight percent number is 1% treated starch in above-mentioned emulsion, and these treated starches partly are made up of by amylopectin the amylose starch and the residue thereof that are no more than 27%.
The present invention also provides a kind of pH value can reach the composition of 10 latex, and it is made up of the following polymkeric substance of respectively organizing:
(a) a kind of C that contains
4-C
6The homopolymer of conjugated diolefine;
(b) a kind of multipolymer that constitutes by following monomer
(ⅰ) contain the C of weight percentage 40 to 20
8-C
