Environment-friendly exothermic material for floor and preparation method of environment-friendly exothermic material

Abstract

The invention discloses an environment-friendly exothermic material for a floor and a preparation method of the environment-friendly exothermic material. The environment-friendly exothermic material is prepared from the following raw materials in parts by weight: 20-30 parts of an exothermic dry powder material, 1-10 parts of a binder and 80-120 parts of polyurethane, wherein the exothermic dry powder material is prepared by the following steps: weighing raw materials of components of the exothermic dry powder material, then adding the raw materials into a stirrer, and uniformly carrying out mixing by stirring to obtain the exothermic dry powder. According to the invention, various auxiliaries are added into waste polyester bottles, so that the prepared polyurethane heat-preservation material is more friendly to environment; the heat-preservation material is low in heat conductivity coefficient, good in flame retardancy, low in water absorption rate, and high in compression strength; and a mixture A is added into the polyurethane material as a filler, so that the prepared environment-friendly exothermic material has good mechanical property and electrical property, temperature rising is rapid, and exothermicity is uniform.

Description

Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide an environmentally friendly heating material for flooring and its preparation method. The polyurethane thermal insulation material prepared by adding various additives to discarded polyester bottles is more environmentally friendly. , and the insulation material has low thermal conductivity, good flame retardancy, low water absorption and high compressive strength; by adding the mixture A as a filler to the polyurethane material, the prepared environmentally friendly heating material has good mechanical properties and electrical properties, Fast heating, uniform heating, can avoid local overheating, and low cost of production raw materials, low power consumption, energy saving and environmental protection, safety and low carbon, the production process has zero pollution to the environment; at the same time, the process is simple, suitable for production, and reduces costs ;Mixture A is simple in design, fast in temperature rise, uniform in heat generation, can avoid local overheating, and has low raw material cost, low power consumption, energy saving and environmental protection, safety and low carbon, and zero pollution to the environment during the production process; phenolic resin and dextrin The mixture is a binder, which will slowly decompose during combustion to produce hydrogen, hydrocarbons, water vapor and carbon oxides. It is non-toxic and harmless, and does not hinder the contact of reactants.
