Abstract
The present invention relates to thixotropic furan resin for winter construction in anticorrosion engineering. A certain number of solidifying agents and fillers are added into the existing furan resin. The solidifying agent is prepared by mixing 50 to 70% of organic acid and 30 to 50% of thixotropic agent. The present invention has favorable anticorrosion performance and can be normally solidified under the condition of temperature below 10DEGC. The present invention can be rapidly solidified under the normal temperature condition, mortar can not flow during masonry construction, and the present invention can be widely used for the anticorrosion engineering of the fields of metallurgy, chemical industry, pharmacy, etc.
Description
The present invention relates to chemical field, is a kind of ideal impregnating material.
Furane resin are meant the thermosetting polymer of furan nucleus polymkeric substance on the main chain, be that main raw material forms through condensation generally with alditol, chaff ketone or furfuryl alcohol, having performances such as alkaline-resisting, acidproof, organic solvent-resistant, anti-comparatively high temps, is a kind of comparatively ideal impregnating material.
YH type, the FS-90 type furane resin of domestic production at present, be a kind of furfuryl alcohol furfural type furane resin of the HB of adding solidifying agent, its finished product ultimate compression strength is 70MPa, and tensile strength is 6MPa, with the ceramic tile cohesive strength be 1MPa, maximum operation (service) temperature is not more than 140 ℃.
XLZ-2 type furane resin are the developments by existing furane resin, resin curing agent, X admixture, the furfuryl alcohol of the X admixture of succeeding in developing-furfural type furane resin, its finished product are completely solidified at normal temperatures, its ultimate compression strength is not less than 80MPa, tensile strength is not less than 8MPa, with the ceramic tile cohesive force greater than 2.5MPa, maximum operation (service) temperature is 180 ℃.
More than several furane resin all have corrosion resistance nature preferably, but when 10 ℃ of following conditions, can not normally solidify, can not fast setting in normal temperature condition, clay easily trickles when building construction.
The objective of the invention is the problem that exists at existing furane resin, providing a kind of can normally solidify when 10 ℃ of following conditions, and can quick-setting winter construction under normal temperature condition, thixotropic furan resin.
Concrete scheme of the present invention is to add filler and solidifying agent, particularly this solidifying agent are to be mixed by the carboxylic acid R-COOH of 50-70% or polyvinyl alcohol or the polyacrylic acid of thionothiolic acid R-COSH and 30-50% in furane resin.
Experiment showed, that the present invention is not more than 12 hours-5 ℃ of conditions following set time, and be not more than 2 hours the set time under 20 ℃ of conditions.The present invention can make resin normal construction and curing under cold condition, does not trickle when building construction, can not be subjected to seasonal effect, saves a large amount of insulation measure costs, reduces the loss of stopping work, stop production.
The invention will be further described below in conjunction with embodiment:
Embodiment 1: get carboxylic acid R-COOH5 kilogram, polyvinyl alcohol carries out mixed solidifying agent, drying, the grinding again of getting for 5 kilograms; Get 200 kilograms of furane resin, 600 kilograms of quartz fillers and above-mentioned solidifying agent are mixed thoroughly and are promptly got winter construction, thixotropic furan resin.
Embodiment 2: get thionothiolic acid R-COSH70 kilogram, polyacrylic acid carries out mixed solidifying agent, drying, the grinding again of getting for 30 kilograms; Get 500 kilograms of furane resin, get 1500 kilograms of graphite packings, mix thoroughly with above-mentioned solidifying agent and get final product.
Claims (1)
1. a kind of winter construction, the thixotropic furan resin that are used for antiseptic project, be to add filler and solidifying agent in furane resin, it is characterized in that: solidifying agent is mixed by the carboxylic acid R-COOH of 50-70% or polyvinyl alcohol or the polyacrylic acid of thionothiolic acid R-COSH and 30-50%.
