Problems solved by technology

However, traditional emergency materials, such as sponges, absorbent paper, and absorbent cotton, can only absorb about 20 times their own weight at most, and the absorbed water is easily squeezed out after being squeezed, which is not convenient for transportation.

Abstract

The invention discloses an environmental protection emergency material, a preparation method and a regeneration method thereof, and belongs to the technical field of domestic waste recycling. The method of the present invention is to collect and clean the waste diapers, peel off the outer fabric to take out the filling material and mechanically break it to obtain the filling material particles, then dry the filling material particles for standby; take the adsorption material; mechanically break it to obtain the auxiliary material Adsorptive powder, ready for use; take the dried filler particles and auxiliary material absorbent powder according to the formula ratio, mix them evenly in a dry place, and get the environmental protection emergency material. The environmental protection emergency material of the present invention can quickly and efficiently absorb organic pollution liquid leaked due to accidents in large quantities, and has low cost, wide sources of raw materials, and environmentally friendly treatment process, which can turn waste diapers into treasures and realize resource utilization. change.

Description

Technical field [0001] The present invention relates to an environmentally friendly material and preparation method and the emergency regeneration methods, resources belonging to the technical field garbage waste. Background technique [0002] Baby diapers commonly used daily, is diapers, diapers, collectively pulling pants. Dry diapers can keep the baby sleep all night because of the strong water absorption, is known as the * # * # * * diapers. Wherein the superabsorbent polymer is manufactured baby diapers excellent material, water absorption and prominent features surprisingly large. Physiological saline absorption of 40 to 60 times its own weight, the absorption of pure water is 50 to 100 times its own weight. Diapers user groups are mainly infants and adults into two categories. Where the Chinese market is mainly baby diapers, China has nearly 20 million babies are born each year, using diapers aged 0 to 2 years old infants reach 40 million. According to the National Bureau ...
