【摘要】：近年來,我國水泥混凝土路面發(fā)展很快,其在我國道路建設(shè)中占據(jù)著主導(dǎo)地位。水泥混凝土路面壽命的長(zhǎng)短與水泥混凝土路面填縫材料性能的優(yōu)劣有直接關(guān)系,如何得到性能優(yōu)良兼顧成本低廉的高性價(jià)比填縫材料,是困擾眾多研究者多年的技術(shù)難題。目前,國內(nèi)應(yīng)用較多的是聚氨酯型填縫材料,當(dāng)有水存在時(shí)異氰酸酯基會(huì)與水反應(yīng)并釋放CO2氣體,使接縫材料膠層起泡而影響性能,雨霧天氣限制了聚氨酯型填縫材料的正常施工。本研究旨在研究出一種可以帶水施工的復(fù)合型水泥混凝土路面填縫材料。制備了一種水性膠粘劑復(fù)合橡膠條作為接縫材料。同時(shí)制備了一種水溶性超支化聚酰胺-酯改性水性膠粘劑,水溶性超支化聚合物末端大量的極性基團(tuán)會(huì)增加接縫界面與橡膠嵌縫條的粘結(jié)強(qiáng)度。還制備了一種界面劑預(yù)先涂刷于接縫基層,降低了接縫表面結(jié)構(gòu)缺陷對(duì)填縫材料粘結(jié)強(qiáng)度造成的不良影響。該填縫材料綠色環(huán)保,施工操作簡(jiǎn)單,成本低廉。本研究主要由以下幾部分組成:1.復(fù)合型填縫材料的制備首先用聚合物乳液與助劑制備出水性膠粘劑,然后復(fù)合9種不同種類橡膠嵌縫條作為填縫材料。對(duì)復(fù)合型填縫材料進(jìn)行粘結(jié)強(qiáng)度、耐高溫、負(fù)溫抗裂性、熱壓冷拉、耐老化性能測(cè)試。通過性能測(cè)試,優(yōu)選出了聚氨酯橡膠嵌縫條-填縫材料和天然橡膠嵌縫條-填縫材料。2.水溶性超支化聚酰胺-酯合成及表征(WHPAE)首先用丁二酸酐與二異丙醇胺反應(yīng)合成AB2型增長(zhǎng)單體,再以三羥甲基丙烷為核分子制備出超支化聚合物,通過控制核分子與AB2型增長(zhǎng)單體的比例得到第一代、第二代、第三代超支化聚合物。再用丁二酸酐對(duì)上述超支化聚合物進(jìn)行改性,得到末端為羧基的超支化聚合物,最后用二乙醇胺與端羧基超支化聚合物反應(yīng)得到第一代、第二代、第三代水溶性超支化聚酰胺-酯溶液(WHPAE)。用紅外譜圖、羥值測(cè)定、元素分析測(cè)試手段對(duì)WHPAE進(jìn)行表征,通過對(duì)測(cè)試結(jié)果分析得出合成的產(chǎn)物是結(jié)構(gòu)比較完整。3.對(duì)水性膠粘劑改性后填縫材料的性能測(cè)試把合成的WHPAE添加到水性膠粘劑中,在復(fù)合橡膠嵌縫條作為填縫材料進(jìn)行粘結(jié)強(qiáng)度性能測(cè)試。結(jié)果表明膠粘劑改性后,填縫材料粘結(jié)強(qiáng)度得到了提高。WHPAE G1的最佳添加量為8%,WHPAE G2和WHPAE G3的最佳添加量為6%。4.路面接縫界面劑的制備及性能測(cè)試用合成的不同代數(shù)的水溶性超支化聚酰胺-酯溶液、水性膠粘劑和水按1:2:4的配比制備出路面接縫界面劑。在填入填縫材料前將界面劑涂刷于接縫界面基層,晾干后再填入填縫材料。實(shí)驗(yàn)結(jié)果表明用界面劑處理接縫后,填縫材料與接縫的粘結(jié)強(qiáng)度得到了提高。
[Abstract]:In recent years, cement concrete pavement has developed rapidly in China, which occupies a leading position in road construction in China. The length of life of cement concrete pavement is directly related to the performance of cement concrete pavement jointing material. How to obtain high performance and low cost ratio filling material with good performance and low cost is a technical problem that has been puzzling many researchers for many years. At present, polyurethane filling materials are widely used in our country. When there is water, isocyanate group will react with water and release CO _ 2 gas, which will make the joint material foam and affect its performance. Rain and fog weather restricted the normal construction of polyurethane type joint filling materials. The purpose of this study is to develop a composite cement concrete pavement jointing material which can be constructed with water. A kind of waterborne adhesive compound rubber strip was prepared as joint material. A water-soluble hyperbranched polyamide-ester modified waterborne adhesive was also prepared. A large number of polar groups at the end of the water-soluble hyperbranched polymer increased the bond strength between the joint interface and the rubber seam strips. An interfacial agent was also prepared to prebrush the joint base to reduce the negative effect of the surface structure defects on the bonding strength of the filler. The joint filling material is green and environmental friendly, easy to operate and low in cost. This research mainly consists of the following parts: 1. The preparation of composite seams was made by using polymer emulsion and additives to prepare waterborne adhesives, and then 9 different kinds of rubber stitching strips were used as filling materials. The bonding strength, high temperature resistance, negative temperature crack resistance, hot pressing and cold drawing, aging resistance of the composite filler were tested. Through the performance test, the polyurethane rubber joint material and the natural rubber intercalation material. 2. 2 were selected. Synthesis and characterization of water-soluble hyperbranched polyamide-ester (WHPAE) A _ 2 growth monomer was synthesized by the reaction of succinic anhydride with diisopropanolamine, and then the hyperbranched polymer was prepared by using trihydroxymethyl propane as nuclear molecule. The first generation, second generation and third generation of hyperbranched polymers were obtained by controlling the ratio of nuclear molecules to AB2 growth monomers. The hyperbranched polymers were modified with succinic anhydride to obtain hyperbranched polymers with carboxyl end groups. Finally, the first and second generation of hyperbranched polymers were obtained by the reaction of diethanolamine with carboxyl terminal hyperbranched polymers. Third generation water-soluble hyperbranched polyamide-ester solution (WHPAE). WHPAE was characterized by IR spectrum, hydroxyl value determination and elemental analysis. The result showed that the synthesized product was relatively complete. The properties of the water-based adhesive were tested by adding the WHPAE to the waterborne adhesive. The adhesive strength was tested by using the composite rubber intercalation strip as the filling material. The results showed that the bond strength of the filler was improved by the adhesive modification. The optimum addition amount of 8WHPAE G2 and WHPAE G3 was 6. 4. Preparation and performance testing of pavement joints Interfacial agents were prepared with different algebraic water-soluble hyperbranched polyamide-ester solutions, water-borne adhesives and water at 1:2:4 ratio for the preparation of pavement joint interfacial agents. Apply the interface agent to the interface base before filling in the seam filling material, then dry and fill in the seam filling material. The experimental results show that the bond strength between the filler material and the joint is improved after the interface agent is used to treat the joint.
