Abstract

The invention relates to a surfactant composition and its application. The application contains polyoxyethylene nonyl phenyl ether and an anionic surfactant. The invention also relates to a method for evaluating the point load performance of a plastic tube by using the surfactant composition. The use of the surfactant composition in environmental stress crack resistance evaluating test and low speed crack increase resistance evaluating test substantially shortens the evaluating time.

Description

technical field [0001] The present invention relates to a surfactant composition, the application of the surfactant composition in the environmental stress cracking resistance performance evaluation test and the slow crack growth resistance performance evaluation test, and the point load performance using the surfactant composition evaluation method. Background technique [0002] Polyethylene is prone to cracking under the synergistic effect of various environmental factors and stress conditions, that is, environmental stress cracking. Polyethylene is a class of materials that is extremely sensitive to environmental stress cracking, which often determines the service life of polyethylene products. Therefore, it is particularly important to evaluate the stress cracking performance of polyethylene resin and its products, and it is also an important research topic to develop polyethylene resin with excellent environmental stress cracking resistance. Polyethylene resin is wide...
