Description
技术领域technical field
本发明涉及涂料底涂剂技术领域，更具体的说是涉及一种隧道衬砌结构防护涂料配套用环氧封闭底层材料。The invention relates to the technical field of paint primers, and more particularly relates to an epoxy sealing primer material for supporting coatings for tunnel lining structures.
背景技术Background technique
隧道在运营后衬砌混凝土结构因地质灾害、运营年限、气候条件等多种原因产生各种缺陷或病害，有的在隧道建成后短时间内，甚至隧道建设过程中就出现了衬砌开裂掉块、衬砌背后空洞、蜂窝麻面、衬砌施工缝错位等缺陷。隧道衬砌质量缺陷易导致材料裂化、衬砌掉块、渗漏水等病害，严重威胁线路运营安全。在隧道衬砌表面增加一层具有一定延伸率、强度较高聚氨酯体系涂层能够很好解决衬砌掉块问题。常规环氧底涂剂硬度较大，与高强度聚氨酯配套性差，附着力及剥离强度低，柔性环氧强度低，难以满足高强度聚氨酯防护体系。After the tunnel is in operation, the lining concrete structure has various defects or diseases due to various reasons such as geological disasters, operating years, and climatic conditions. Defects such as voids behind the lining, honeycomb pitted surface, and dislocation of lining construction joints. Defects in the quality of tunnel lining can easily lead to material cracking, lining drop, water leakage and other diseases, which seriously threaten the safety of line operation. Adding a layer of polyurethane system coating with a certain elongation and high strength on the surface of the tunnel lining can solve the problem of lining block loss. Conventional epoxy primers have high hardness, poor compatibility with high-strength polyurethane, low adhesion and peel strength, and low flexible epoxy strength, making it difficult to meet high-strength polyurethane protection systems.
现有环氧底涂剂产品大多存在韧性与强度难以同时满足，封闭底强度高及韧性较好的底涂剂在国内有关该类的改进方法鲜有报道。Most of the existing epoxy primer products have toughness and strength that are difficult to satisfy at the same time, and primers with high sealing bottom strength and good toughness are rarely reported in China on such improvement methods.
因此，如何提供一种强度高、韧性好且在混凝土基材上具有较高的附着力的隧道衬砌结构防护涂料配套用环氧封闭底层材料是本领域技术人员亟需解决的问题。Therefore, it is an urgent problem for those skilled in the art to provide an epoxy sealing bottom material for tunnel lining structure protective coatings with high strength, good toughness and high adhesion on concrete substrates.
发明内容SUMMARY OF THE INVENTION

优选地，所述组分A包括以下重量份数的原料：Preferably, the component A includes the following raw materials in parts by weight:
环氧树脂：50份Epoxy resin: 50 parts
触变剂：1.2份Thixotropic agent: 1.2 parts
润湿分散剂：0.3份Wetting and dispersing agent: 0.3 part
150#溶剂油：15份150# solvent oil: 15 parts

KH550：6份KH550: 6 servings
流平剂：0.8份Leveling agent: 0.8 parts
消泡剂：0.8份。Defoamer: 0.8 part.
优选地，所述改性聚酰胺为环氧固化剂Ancamide2766。Preferably, the modified polyamide is Ancamide2766, an epoxy curing agent.
优选地，所述触变剂为气相二氧化硅和/或聚脲触变剂。所述聚脲触变剂为BYK410。Preferably, the thixotropic agent is fumed silica and/or polyurea thixotropic agent. The polyurea thixotropic agent is BYK410.
更加优选地，所述触变剂为气相二氧化硅和聚脲触变剂的混合物；所述气相二氧化硅的重量份数为0.5-1份，所述聚脲触变剂的重量份数为0.5-1份。More preferably, the thixotropic agent is a mixture of fumed silica and polyurea thixotropic agent; the weight part of the fumed silica is 0.5-1 part, and the weight part of the polyurea thixotropic agent 0.5-1 serving.

本发明采用了聚脲和气相二氧化硅的复配体系来控制产品的一次成膜厚度和成膜的流平性。聚脲属于有机类流变改性剂，通过分子间氢键的相互作用形成网状结构而具有一定触变性，受到物理剪切力时，分子间氢键受到破坏，粘度降低，当停止剪切后，聚脲分子间氢键又重新相互作用，从而粘度增减，由于粘度回复的速度较慢使得环氧底漆具有流动性和流平性，不会导致立面流挂失控；气相二氧化硅属于无机类流变改性剂，主要依靠氢键结构产生触变性，在剪切力下氢键被破坏，粘度降低，剪切力消除后又重新形成氢键结构，粘度恢复，提供良好的抗流挂性能，温度升高也能使气相二氧化硅中的氢键作用减弱，粘度降低。两种材料的复配使用能够提供良好的抗流挂性能的同时，施工性加好。因此，气相二氧化硅的重量份数为0.7份，所述聚脲的重量份数为0.7份时效果最好，最终本产品能够达到一次性涂装膜厚100-300微米。The present invention adopts the compound system of polyurea and fumed silica to control the thickness of the first film formation and the leveling property of the film formation. Polyurea is an organic rheology modifier, which forms a network structure through the interaction of intermolecular hydrogen bonds and has a certain thixotropy. When subjected to physical shearing force, the intermolecular hydrogen bonds are destroyed and the viscosity is reduced. When the shearing stops After that, the hydrogen bonds between the polyurea molecules interact again, so that the viscosity increases or decreases. Due to the slow recovery of the viscosity, the epoxy primer has fluidity and leveling, and will not cause the facade to sag and run out of control; gas-phase dioxide Silicon is an inorganic rheology modifier, which mainly relies on the hydrogen bond structure to generate thixotropy. Under the shear force, the hydrogen bond is destroyed and the viscosity is reduced. Anti-sag properties, and increasing temperature can also weaken hydrogen bonding in fumed silica and reduce viscosity. The compound use of the two materials can provide good sag resistance and improve workability at the same time. Therefore, the weight part of fumed silica is 0.7 part, and the effect is the best when the weight part of the polyurea is 0.7 part, and finally this product can achieve a one-time coating film thickness of 100-300 microns.
优选地，所述环氧树脂为E-44环氧树脂。Preferably, the epoxy resin is E-44 epoxy resin.
优选地，所述的润湿分散剂为TEGO Dispers 710。Preferably, the wetting and dispersing agent is TEGO Dispers 710.
本发明经过大量的分散剂筛选试验，最终确定采用润湿分散剂为TEGO Dispers710作为分散助剂使用，此助剂的应用一方面提高了产品的分散效率，一方面有效的降低了产品的粘度，增加了产品的流动性。After a large number of dispersant screening tests in the present invention, it is finally determined that the wetting and dispersing agent is TEGO Dispers710 as a dispersing auxiliary. The application of this auxiliary improves the dispersion efficiency of the product on the one hand, and effectively reduces the viscosity of the product on the one hand. Increased product liquidity.
优选地，所述滑石粉为1250目与800目的混合物，且所述滑石粉1250目与800目质量比为(0.8:1)-(1.2:1)。Preferably, the talc powder is a mixture of 1250 mesh and 800 mesh, and the mass ratio of the 1250 mesh to 800 mesh of the talc powder is (0.8:1)-(1.2:1).
更加优选地，所述滑石粉1250目的重量份数为8.3份，滑石粉800目的重量份数为7.2份。More preferably, the 1250 mesh talc powder is 8.3 parts by weight, and the 800 mesh talc powder is 7.2 parts by weight.
本发明采用了滑石粉为1250目与800目复配体系来提高环氧底涂剂的强度从而达到高拉拔强度及剥离强度的要求。1250目滑石粉比表面积大，与环氧树脂接触面积大，相容性好，在树脂中形成海岛结构增加了体系力学性能，800目滑石粉也可有增加一定强度，采用1250目滑石粉与800目滑石粉复配满足了提高底涂剂力学强度的要求又满足了施工性要求。The invention adopts the compound system of 1250 mesh and 800 mesh of talc to improve the strength of the epoxy primer so as to meet the requirements of high pulling strength and peeling strength. 1250 mesh talc powder has a large specific surface area, a large contact area with epoxy resin, and good compatibility. The formation of sea-island structure in the resin increases the mechanical properties of the system. 800 mesh talc powder can also increase a certain strength. The compounding of 800 mesh talc powder meets the requirements of improving the mechanical strength of the primer and the requirements of construction.
