Problems solved by technology

Cement-based waterproof materials have good durability and are fully compatible with the base surface, but they are not suitable for deformation, and the waterproof effect is not ideal; polymer waterproof materials are adaptable to deformation, but have poor compatibility with the base surface, and have aging problems, and their durability is insufficient
The polymer cement-based waterproof coating prepared by combining the two has made up for the defects of the two materials to a certain extent, but there are still some defects such as insufficient tensile strength, cold and heat resistance, poor aging resistance, and partial shear strength and bonding strength. Low level defects

Abstract

The invention relates to a bi-component waterproof paint for roads and bridges and a preparation method thereof. The waterproof paint comprises 10-70% of emulsion and auxiliary agents as component A and 30-90% of cement, quartz sand as well as wood powder as component B. By weight, the component A comprises 5-50% of emulsion, 0.1-10% of plasticizing agent, 0.1-4% of defoaming agent, 0.1-3% of softening agent, 0.1-4% of antifreeze agent, 0.1-3.5% of thickening agent, 0.1-2% of preservative and the balance of water; and the component B comprises 10-50% of cement, 8-40% of quartz sand and 0.5-5% of wood powder. The invention has the following advantages that the bi-component waterproof paint for roads and bridges is prepared through the synergistic effect of compounding and superposing various materials; and the waterproof paint has great tension strength and excellent ageing resistance, water resistance, heat resistance and cold resistance, and has superior bonding strength and shear strength.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to a two-component waterproof coating for roads and bridges and a preparation method thereof. Background technique [0002] In traditional waterproofing technology, cement is used for rigid waterproofing, and polymer materials are used for flexible waterproofing. Cement-based waterproof materials have good durability and are fully compatible with the base surface, but are not suitable for deformation, and the waterproof effect is not ideal; polymer waterproof materials are adaptable to deformation, but have poor compatibility with the base surface, and have aging problems, and their durability is insufficient. The polymer cement-based waterproof coating prepared by combining the two has made up for the defects of the two materials to a certain extent, but there are still some defects such as insufficient tensile strength, cold and heat resistance, poor aging resistance, and partial shear stre...
