Abstract

The invention relates to a preparation method of cooling core, especially a preparation technology of flame retardant type evaporative-cooling core. It adopts water soluble phenolic resin to solidify glass fiber materials. The soluble resins solidified on the glass fiber materials are propitious to improve their structure and later molding. The polymer structure of the resins has certain hydrophilicity, which can improve the stream distribution of the cooling core during its using, is benefits the formation of the water film and advance the humidifying efficiency. They also have features of flame retardant, weather resistant and heat resistant, which can meet the flame retardant function of the final production. The solidified weight percentage of the resins adsorbing to the glass fiber materials should be controlled between 5-25%. The solidification amount of the adsorbed soluble resins of the glass fiber materials affects the intensity and water absorption of the final productions.

Description

Technical field: [0001] The invention relates to a manufacturing method of a cooling core, in particular to a manufacturing process of a flame-retardant evaporative cooling core. Background technique: [0002] The evaporative cooling core is an integral part of the evaporative cooling fan cooling system, which is used in high-temperature workshops, textile mills, etc. in industry. In agriculture, it is often used in greenhouses and livestock houses. Its investment cost is only 10-15% of the general refrigeration and air-conditioning system. At present, the evaporative cooling core usually used for air humidification and cooling refers to a core formed by vertically stacking several cooling paper media. They are superimposed at a certain angle to form a number of interlaced channels, which are divided into water channels and air channels. The cooling core is mainly made of fiber paper, which has potential safety hazards in the production process and storage. Dry fiber pape...
