Abstract

The invention discloses a rat-proof termite-proof condensation-proof foam material and a preparation method and application thereof. The preparation method comprises the following steps: preparing anorganic / inorganic polymer composite emulsion; mixing a silane coupling agent with a rat repellent, and adding polyisocyanate, aliphatic carboxylic acid and hydroxymethyl melamine to obtain a first mixture; adding polyisocyanate and a catalyst into polymer polyol, then adding the first mixture, finally adding an organic matter foaming agent and a foam stabilizer, and carrying out uniform mixing toprepare a polyurethane prepolymer; and mixing the organic / inorganic polymer composite emulsion and the polyurethane prepolymer to prepare a component A, mixing cement, styrene resin, paraffin and water to prepare a component B, mixing the component A and the component B, carrying out quick stirring, and performing curing at room temperature to obtain the rat-proof termite-proof condensation-prooffoam material. The rat-proof termite-proof condensation-proof foam material prepared by using the method has excellent condensation-proof, rat-proof and termite-proof effects.

Description

technical field [0001] The invention belongs to the technical field of composite material preparation, and in particular relates to a rodent-proof and condensation-proof foam material, a preparation method and an application. Background technique [0002] With the rapid development of science and technology, industrial production is gradually developing in the direction of mechanization and automation, and the demand for electricity has also reached a new height. Electrical equipment is a powerful guarantee for power supply. However, during the use of electrical equipment, when the temperature of the inner wall surface of the electrical equipment cabinet drops below the dew point temperature, water droplets will be formed on the inner wall surface, and this phenomenon is very common, making electrical equipment operate safely. be greatly affected. [0003] During the use of electrical equipment, when the temperature of the inner wall surface of the electrical equipment cabi...
