Abstract

The invention provides special adhesive resin for a polyvinyl chloride corrosion-resistant steel tube with a barrier property. The resin comprises the following components in parts by weight: 20-30 parts of an ethylene-vinyl acetate copolymer, 15-20 parts of maleic anhydride-grafted polyvinyl chloride, 15-20 parts of maleic anhydride-modified polypropylene, 10-15 parts of polyurethane-modified epoxy resin, 10-15 parts of tripolyphosphoric acid-modified polyvinyl alcohol resin, 10-15 parts of terpene resin, 5-10 parts of filler and 0.1-0.5 part of an antioxidant. The invention also provides a preparation method of the special adhesive resin for the polyvinyl chloride corrosion-resistant steel tube with the barrier property. The adhesive resin for the polyvinyl chloride corrosion-resistant steel tube with the barrier property has a good adhesive property on a polar material, has relatively high shear strength and relatively good low-temperature resistance, has relatively high peeling strength in a relatively wide temperature range, and is wide in application range.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a special adhesive resin for polyvinyl chloride anticorrosion steel pipes with barrier performance and a preparation method thereof. Background technique [0002] The anti-corrosion steel pipe is mainly used for the transportation of oil, gas and water. It will greatly improve the barrier property of the adhesive resin in the middle layer of the anti-corrosion steel pipe and the sealing of the anti-corrosion pipe, and improve its safety while transporting oil, gas and water. However, the PVC anti-corrosion steel pipes on the market generally have cracks and other phenomena after a period of use, which increases the risk of use. This is mainly because: 1. The shear strength and peel strength of the bonding resin are not good, and when the temperature changes, peeling or slipping occurs; 2. The bonding strength of the bonding resin is not enough, especially for difficult F...
