Abstract

The invention provides a foamed material with insulation and a preparation method thereof, and belongs to the technical field of foamed material preparation. The material comprises the following raw materials in percentages by weight: 40-50% of toluene diisocyanate, 15-20% of polyether polyol, 3-6% of expanded vermiculite, 1-3% of silica, 2-8% of dichlorodifluoromethane, 2-8% of an organic pigment, 2-8% of a catalyst, 1-3% of a foam stabilizer, and the balance being water. The preparation method has intelligible principle and simple processing method, and compared with foamed materials prepared by traditional methods, the product has more excellent compressive strength, tensile strength and impact strength; in addition, compared with the prior art, the polyurethane foam insulation materialhas high thermal insulation performance of common polyurethane foamed materials, and the problem of foam shrinkage caused by itself characteristics, production process, production worker operation ability and other aspects are is reduced, and the phenomenon of deformation, bulge, barring, even cracking of water tanks is avoided.

Description

technical field [0001] The invention belongs to the technical field of foam material preparation, and relates to a foam material, in particular to a thermal insulation foam material and a preparation method thereof. Background technique [0002] With the increasing shortage of energy and the increasing pressure on environmental protection, countries around the world have begun to promote the development of renewable energy, among which solar energy is the most widely used and developed renewable energy with the best development prospects, and has been widely used in various industries , the solar water heater industry is one of them. Our country is rich in solar energy resources and has broad prospects for solar energy utilization. At present, it is the first user and producer of solar water heaters in the world. [0003] As we all know, for solar water heaters, the selection of water tank insulation materials is very important. At present, the insulation materials that can...
