Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of road engineering, and relates to a fog seal material, in particular to a high-permeability and high-adhesion fog seal material and a preparation method thereof. BACKGROUND

[0002] The application of the fog seal technology can effectively improve the waterproof performance of the asphalt pavement, thereby effectively improving the anti-skid performance of the pavement, delaying the aging speed of the pavement, and improving the appearance of the asphalt pavement. The fog seal technology, namely the fog seal technology, mainly sprays emulsified asphalt, asphalt maintenance agent and other materials onto the pavement to seal the pores on the pavement, and at the same time, fixes the loose aggregate in construction, which has a positive significance in preventing pavement aging. As a preventive construction and maintenance technology, the improved pavement needs to have strong rigidity and stability without changing the original structure and strength of the pavement and increasing the bearing capacity. The fog seal technology is generally applied to the asphalt pavement with slight cracks and early water damage.

[0003] The fog seal used in China mainly includes sand-containing fog seal and sand-free fog seal. The sand-containing fog seal is generally widely used because it can improve the anti-skid performance. The cementing material used in the sand-containing fog seal is emulsified asphalt. However, the permeability of the emulsified asphalt is relatively poor, and it is difficult to penetrate into the original pavement, resulting in poor maintenance effect of the asphalt pavement. Therefore, a fog seal material with high permeability and high adhesion is needed. SUMMARY

[0004] In view of the deficiencies in the prior art, the purpose of the present application is to provide a high-permeability and high-adhesion fog seal material and a preparation method thereof, which solves the technical problem that the fog seal material in the prior art is difficult to have high permeability and high adhesion while ensuring basic performance.

[0020] Step three, preparation of modified sodium carboxymethyl cellulose:

[0021] First, add sodium carboxymethyl cellulose into anhydrous ethanol, and ultrasonic dispersion for 15-20 min to obtain a suspension. Then, mix γ-glycidyl ether oxypropyl trimethoxysilane and water, and stir until it is cooled to room temperature. Stop stirring and then add it to the suspension, and ultrasonic dispersion for 15-20 min. In a constant temperature magnetic stirrer, condense and reflux the reaction at 70°C for 3 h. After the reaction is completed, repeatedly wash and suction filter with anhydrous ethanol until the filtrate is clear and transparent. Place the filter cake in a vacuum drying oven and dry at 70°C to obtain sodium carboxymethyl cellulose particles. Put them into a ball mill and grind for 2-3 h to obtain modified sodium carboxymethyl cellulose.

[0022] Step four, preparation of tackifier:

[0023] Add polyoxyethylene sorbitan fatty acid ester and the modified sodium carboxymethyl cellulose prepared in step three into water respectively, heat to 80-85°C and stir until completely dissolved. Then, add the two solutions respectively into the modified cyanate ester prepared in step two, and ultrasonic dispersion for 20 min to obtain a mixed solution, which is the tackifier and is recorded as component A.

[0024] Step five, preparation of permeability enhancer:

[0025] Mix bis-ethylhexyloxyphenol methoxyphenyl triazine and methylene bis-benzotriazolyl tetramethyl butyl phenol with water, and ultrasonic dispersion for 30 min to obtain a mixed solution, which is the permeability enhancer and is recorded as component B.

[0026] Step six, preparation of additive:

[0028] Step seven, preparation of semi-finished product:

[0029] Uniformly introduce emulsified asphalt at 130-150°C into the funnel of a high-speed shearing instrument, open the switch of the high-speed shearing instrument, and simultaneously uniformly pour component A prepared in step four into the high-speed shearing instrument. The shearing time is controlled at 40-60 s. Then, uniformly pour component C prepared in step six into the funnel of the high-speed shearing instrument, and the shearing time is controlled at 60-120 s.

[0034] Compared with the prior art, the present invention has the following technical effects:

[0035] (I) In the fog seal material of the present invention, the addition of bis-ethylhexyloxyphenol methoxyphenyl triazine and methylene bis-benzotriazolyl tetramethylbutylphenol alone will not improve the permeability of the fog seal material. When the two are added simultaneously, the permeability of the fog seal material is significantly enhanced. In addition to exerting the high temperature resistance of the material itself, bis-ethylhexyloxyphenol methoxyphenyl triazine and methylene bis-benzotriazolyl tetramethylbutylphenol also produce a synergistic effect. The composite material can significantly improve the permeability of the fog seal material.

[0036] (II) In the mist seal material of the present invention, it can be found that polyoxyethylene sorbitan fatty acid ester and modified sodium carboxymethyl cellulose have a mutually promoting effect, which enhances the bonding strength of the mist seal material. When polysiloxane-modified polyphenyl polymethylene polyisocyanate is added, polyoxyethylene sorbitan fatty acid ester and modified sodium carboxymethyl cellulose have a significant mutually promoting effect, which greatly enhances the bonding strength of the mist seal material.

[0037] (III) The mechanism of action of the present invention's fog seal material: When sprayed onto the existing asphalt pavement surface, the fog seal material can penetrate into the existing asphalt pavement to a depth of 3mm to 6mm. After curing, it can repair cracks and other defects in the existing pavement, providing a waterproofing effect. While penetrating, it can also firmly adhere to the original asphalt pavement. This effectively repairs old asphalt pavement, thereby extending the pavement's service life.

[0038] (IV) The fog seal material of the present invention is simple to prepare, easy to construct, and has significant penetration and bonding effects, and is highly valuable for promotion.

[0235] Table 1 Performance test table of high-penetration high-tack fog seal material

[0236]

[0237] From Table 1, it can be seen that:

[0238] First, by analyzing the various indexes of Example 2 and Comparative Examples 1-4, it can be found that polyoxyethylene sorbitan fatty acid ester and modified sodium carboxymethyl cellulose can promote each other, so that the adhesion strength of the fog seal material is enhanced. In the case of adding polysiloxane modified polyphenyl polymethylene polyisocyanate, polyoxyethylene sorbitan fatty acid ester and modified sodium carboxymethyl cellulose can promote each other significantly, which can well enhance the adhesion strength of the fog seal material.

[0239] Second, by analyzing the various indexes of Example 2 and Comparative Examples 5-7, it can be found that neither bis-ethylhexyloxyphenol methoxyphenyl triazine nor methylene bis-benzotriazolyl tetramethyl butyl phenol can improve the permeability of the fog seal material when added alone. However, when both are added, the permeability of the fog seal material is significantly enhanced. Bis-ethylhexyloxyphenol methoxyphenyl triazine and methylene bis-benzotriazolyl tetramethyl butyl phenol can not only exert the high-temperature resistance of the material itself, but also have a synergistic effect, and the composite material can significantly improve the permeability of the fog seal material.

[0240] Third, by analyzing the various indexes of Comparative Examples 1-9 and Comparative Examples 1-7, it can be found that the performance of Example 2 is the best and the best raw material composition is: the tackifier is polyoxyethylene sorbitan fatty acid ester 25 parts, sodium carboxymethyl cellulose 25 parts, diphenyl dimethoxy silane 25 parts, dimethyl diethoxy silane 25 parts, γ-glycidyl ether oxypropyl trimethoxy silane 10 parts, and polyphenyl polymethylene polyisocyanate 230 parts by weight; the permeability enhancer is bis-ethylhexyloxyphenol methoxyphenyl triazine 6 parts and methylene bis-benzotriazolyl tetramethyl butyl phenol 6 parts by weight; and the additive is n-butyl dimethyl chlorosilane 5 parts and 2-amino-5-bromo-4-isopropyl benzoic acid methyl ester 5 parts by weight.
