AI Technical Summary

Benefits of technology

This new type of fire-fighting boards made from plastic can be lighter than traditional wood or metal ones while still maintain their effectiveness for preventing fires. It also includes an anti-static layer that helps it resist static electricity without losing functionality over time. Additionally, there are other feature improvements like adding nanoparticles to enhance flame retarding properties. Overall these technical benefits help save money by making them more durable and efficient at fighting fires quickly.

Problems solved by technology

The technical problem addressed in this patented text relates to improving the efficiency at which crops can be stored during winter months by reducing their temperature from below zero Celsius (C) towards 0° C or above while also ensuring proper functioning of these crop containers when warming up again after harvesting them outdoors without losing any moisture content due to frost damage caused by rainwater on top.

Abstract

The invention provides a formula of a thermal insulation board special for a refrigeration house. The formula comprises polystyrene foam particles, dispersible latex powder, natural latex, a flame retardant, a foaming agent, a foam stabilizer, nano silicon dioxide, calcium hydroxide, a plasticizer, mica powder, a film-forming agent and color masterbatch. The formula is prepared from the followingraw materials in parts by weight: 1000kg of the polystyrene foam particles, 8-12 kg of the dispersible latex powder, 8-12 kg of the natural latex, 18-22 kg of the flame retardant, 6-8 kg of the foaming agent, 16-20 kg of the foam stabilizer, 10-22 kg of the nano silicon dioxide, 20 kg of the calcium hydroxide, 4-6 kg of the plasticizer, 45-55 kg of the mica powder, 60-70 kg of the film-forming agent and 3 kg of the color masterbatch. The nano silicon dioxide is added in the foaming process, so that the micropore amount is increased, foam holes are closely formed in the surface, the heat conductivity coefficient is reduced, and the fireproof function of the insulation board is improved.
