Abstract

The invention relates to a special coating for a modified cold primer oil pipeline. The special coating comprises 20-30wt% of modified resin, 50-60wt% of an asphalt liquid, 10-12wt% of 52# paraffin, 8-10wt% of talcum powder and 1-5wt% of an assistant. The special coating can be directly sprayed to reduce bubbles brought by brush coating and roll coating; and chlorinated rubber is used as a binder, so the mass fraction of Cl in the coating is 62-65%, and the coating has a good heat resistance. The chlorinated rubber has the advantages of excellent adhesion, chemical corrosion resistance, wear resistance, easy drying, water permeation resistance, flame retardation and the like; and a long term anticorrosion effect is realized, the selection of 52# paraffin makes the coating have toughness, and the chlorinated rubber is used as the binder, and also has a drying prompting effect due to the easy drying property in order to obviously improve the dryness of the asphalt liquid.

Description

Technical field [0001] The present invention involves a pipeline coatings and its preparation methods. Specifically, it is a special coating and preparation method for modified cold base oil pipelines, which belongs to the field of coating technology. Background technique [0002] Cold base oil viscosity is small and has good liquidity.The brushing is brushed on the base surfaces such as concrete, mortar, or wood, which can quickly penetrate into the pores of the grassroots. After the solvent is volatile, it is firmly combined with the base surface.The coating film formed by cold base oil is relatively thin. Generally, it is not used for waterproof materials alone. It is only used for some waterproof materials.Before paving the waterproof oil felt, coated on the grassroots levels such as concrete, mortar, and wood, which can quickly penetrate into the grassroots pores. After the solvent is volatilized, it is firmly combined with the base surface. [0003] Cold base oil can be clo...
