Embodiment 1

[0050] Take 16kg of clean water, add 1.8kg of slow-cracking and fast-setting cationic emulsifier (RC-SMRHJ804 Jiangyin Rongcheng Road and Bridge Company) in the water, add modifier polymer SBR latex 20kg, dispersant naphthalenesulfonic acid formaldehyde mixed sodium salt 2.5kg gram, polyethylene glycol fatty acid 1.5kg after stirring evenly, when the temperature reaches 65°C, continue to stir evenly and keep the temperature. Take 60kg of Sinopec aromatic hydrocarbon base AH-704# heavy traffic asphalt A, 5kg of carbonate cement and heat it to 165°C, stir them together and put them into a colloid mill for grinding at a speed of 6000 rpm. High-strength cold asphalt joint waterproofing glue. The test results show (see Table 2) that the various indicators are ideal, the amount left on the sieve is small, the storage stability is good, the softening point is high, the viscosity is good, and the aging performance is good.

Embodiment 2

[0059] Get 15kg clean water, add 1.5kg polyoxyethylene alkyl quaternary ammonium hydrochloric acid emulsifier, 1.8kg methyl bis-naphthalene sodium sulfonate (NNO), 1.0kg graft copolymerization of polyorganosiloxane and polyhydric alcohol in water stabilizer, stir evenly and heat to 65°C, then add 15kg (acrylonitrile-butadiene-styrene resin ABS) copolymer latex, mix well, keep warm for later use, and take 62kg heavy asphalt B, diatom 6kg of soil is heated to 160°C. After being heated evenly, it enters the colloid mill for grinding together with the prepared solution at the speed of 7000 rpm. After grinding for two minutes, a qualified high-strength cold asphalt joint waterproofing glue can be obtained. The analysis results show (see table 3), the viscosity of colloid, the residual amount on the sieve, and the evaporation residue content reach the specified standard, and the stability of the quasi village is only 0.06 in 24 hours, and the low temperature storage stability has no...

Embodiment 3

[0062] Get 15kg of clean water, add 2kg of RH-C05 amide cationic emulsifier successively, 2.6kg of sodium methylene bis-naphthalene sulfonate MF dispersant, 1.8kg of SaSobit (SaSobit) stabilizer, after stirring evenly, heat up to 65°C, then add 25kg, SBS latex polymer, continue to stir and mix evenly, keep the temperature for later use, and take 55kg of heavy traffic asphalt AH-70#c and heat it to 168°C. After being evenly heated, 10kg of light calcium carbonate is slowly added to the prepared solution and stirred evenly, and then ground in a colloid mill for 2 minutes at a speed of 8000 rpm to obtain a qualified high-strength cold-state asphalt joint waterproofing glue (its properties See Table 3). The colloid has high viscosity, good stability, no coarse particles and agglomerates in low temperature storage, high softening point, strong viscosity and toughness, which is beneficial to the maintenance of the joint glue cover. The original roadbed of Qianrong line in Wuxi urban...

Abstract

The invention relates to high-strength cold asphalt crack-pouring waterproof adhesive and a preparation method thereof. The waterproof adhesive comprises the following components in portion by weight: 15 to 20 portions of modifier polymer, 2.0 to 3 portions of dispersant, 0.5 to 2.0 portions of stabilizing agent, 50 to 60 portions of heavy rubber asphalt, 1.5 to 2.0 portions of emulsifying agent, 15 to 18 portions of purified water, and 4 to 16 portions of curing agent. The waterproof adhesive has the advantages of simple preparation, reliability and excellent properties, can be widely applied to crack pouring for large traffics in cities and countryside, heavy loading high-grade roads, stress absorbing structural layers, waterproof and mist sealing layers or layer sealing mat coats and the like, and remarkably improves water proofing, skid resistance, flatness and abrasion resistances of the roads.

Description

technical field [0001] The invention relates to the field of asphalt glue for road construction, in particular to a high-strength cold-state asphalt joint filling waterproof glue and a preparation method thereof. technical background [0002] Repairing and maintaining road cracking and damage is a worldwide problem in the road industry. In the late 1990s, one of the two important topics in the US Highway Research Program (SHRP) was the construction of crack grouting technology and repair and maintenance operations, which was proposed as a national strategic plan. my country has used the technology of filling joints for more than 40 years. Usually, the joint glue that is solid at room temperature is heated into a liquid state, and then poured into the crack. This process is still used today. The method of hot melting has many disadvantages, wastes a lot of energy, pollutes the environment and endangers the human body. It is a solid filling at room temperature. The joint col...
