Abstract

The article deals with the issues of obtaining anti-corrosion compositions for corrosion protection of oil pipelines. The purpose of this study was to develop effective compositions of anti-corrosion coatings based on recycled polypropylene (PPrc), cotton soap stock, vegetable filler - guzapay; mineral filler wollastonite and montmorillonite (MMT). The proposed process of chemical interaction of the initial compounds in the prescription modification of the soap stock, in the extruder. The authors obtained a new composite of the following composition (wt. %: vegetable filler - guzapaya - 35; mineral filler - wollastonite: MMT (1: 1) - 5; sevilen - 8; soap stock - 30; PPrc - the rest. The composite composition has high performance indicators on the following positions: breaking stress in bending increased by 15-17%; shear strength increased by 10-12%; tensile strength increased by 6-8%; indentation hardness under a given load of the ball increased by 15- 20% impact strength increased by 15-17%, shrinkage during casting decreased by 30-35%. It to protect against corrosion of the main oil pipeline. This composition of the composite is selected on the basis of available and relatively inexpensive components, polyethylene rich, vegetable and mineral fillers.

基于再生聚丙烯和填料的防腐涂料

本文论述了输油管道防腐成分的制备问题。本研究的目的是开发基于再生聚丙烯(PPrc)、棉皂原液、植物填料guzapay的有效防腐涂料组合物;矿物填料硅灰石和蒙脱土(MMT)。提出了配方改性肥皂原液中初始化合物在挤出机中化学相互作用的过程。作者得到了一种新的复合材料，其成分为:蔬菜填料- guzapaya - 35;矿物填料硅灰石:MMT (1:1) - 5;塞维利亚- 8;皂液- 30;PPrc -其余的。该复合材料在以下位置具有较高的性能指标:弯曲断裂应力提高15-17%;抗剪强度提高10-12%;抗拉强度提高6-8%;压痕硬度在一定载荷下提高15- 20%，冲击强度提高15-17%，铸造时收缩率降低30-35%。它可以防止主输油管道的腐蚀。这种复合材料的组成是在可用且相对便宜的成分、富含聚乙烯、植物和矿物填料的基础上选择的。
