Embodiment 1

[0017] Embodiment 1: A kind of preparation method of flexible epoxy resin oil-water separation sponge, epoxy resin and polyether amine D400 prepare sponge, the steps are as follows:

[0018] 1) Preparation of precursor solution: Prepare 2g of epoxy resin and polyetheramine D400 at a mass ratio of 1:0.5, then add 0.5g of isopropanol, mix with a vortex mixer for 2min, and vacuum with a 2Pa vacuum pump for 5min;

[0019] 2) The template is used to shape the precursor solution: put the glass slide in acetone and ultrasonically clean it for 5 minutes, take it out and dry it, and place the sugar cube on the glass slide. Pour the precursor solution evenly on the sugar cube plane to make it wet inside the sugar cube and spread evenly. After standing for 10 minutes, use a 2 Pa vacuum pump to pump out the air bubbles inside the sugar cube;

[0020] 3) Preparation of flexible epoxy resin sponge: put the modified sugar cube in a constant temperature oven at 80°C for 3 h to cure, remove th...

Abstract

The invention belongs to the technical field of preparation of environment-friendly functional materials and aims to overcome the defects in the preparation of existing oil-absorbing sponges, such as complicated process technology, easy falling off of modified substances, poor durability and high price. Provided is a preparation method of a flexible epoxy resin oil-water separation sponge. Epoxy resin and polyether amine cross-linking agent are prepared in proportion, mixed evenly with diluent, and vacuumized to obtain a precursor solution; the substrate is ultrasonically cleaned in acetone, and sugar is placed on the substrate after drying. The precursor solution is evenly poured on the sugar cube plane, and the vacuum pump is left to draw out the air bubbles in the sugar cube, and then solidified in a constant temperature oven. The sugar cube is washed with ultrasonic water, and the water is changed several times. sponge. The method is simple and easy, the price of raw materials is low, the template is easy to remove, the cycle is short, and it does not rely on special equipment; the prepared flexible epoxy resin sponge not only has the high elasticity of commercial sponges, but also has super lipophilic properties. Has broad development prospects.

Description

technical field [0001] The invention belongs to the technical field of preparation of novel environmental protection functional materials, and in particular relates to a preparation method of a flexible epoxy resin oil-water separation sponge. Background technique [0002] With the rapid development of social economy, a large amount of wastewater containing organic matter is produced. In particular, marine pollution incidents such as oil spills are prone to occur in the process of oil extraction, transportation, and storage (such as oil spills in the Gulf of Mexico, direct leakage accidents from oil wells in the Bohai Bay). These oil-polluted water sources have caused great damage to the ecological environment and human beings. In order to solve the problem of oily wastewater, a large number of adsorbent materials have been developed. This method is widely used because of its simplicity, fast oil absorption rate, and no secondary pollution. In particular, artificially syn...
