Abstract

The invention discloses a composition for preparing a vapor barrier and a preparation method of the composition. The composition comprises the following components in parts by weight: 50-80 parts of polyurethane, 40-60 parts of modified epoxy resin, 10-20 parts of a flame retardant, 5-10 parts of a coupling agent and 20-30 parts of an additive. The method comprises the following steps: (1) mixingthe polyurethane and the modified epoxy resin according to the formula, and crushing the mixture into organic particles with a particle size of 600-800-mesh; (2) mixing the flame retardant and the additive, and crushing the mixture into mixed particles with a particle size of 100-140-mesh; and (3) mixing the product obtained in the step (1) and the product obtained in the step (2), then adding thecoupling agent, carrying out extruding and melting, and then carrying out mixing for 30-60 minutes. The composition prepared by the preparation method disclosed by the invention has excellent bondingperformance, frost resistance and the like, and has a wide application range.

Description

technical field [0001] The invention belongs to the technical field of vapor barrier preparation, and in particular relates to a composition for preparing a vapor barrier and a preparation method thereof. Background technique [0002] Since the reform and opening up, the construction scale of my country's cold storage has grown from small to large, from small to large, and has developed rapidly throughout the country, especially in coastal areas and fruit and vegetable production areas. It has occupied a very important role in the national economy. At present, in the design and construction of cold storage, the role of the vapor barrier is ignored, resulting in shortened service life of the cold storage and serious waste of energy, which greatly increases the operating cost of the cold storage and weakens the competitiveness of the enterprise. [0003] The vapor barrier is a layer of protective material with good air and water tightness to prevent indoor water vapor from pene...
