Description
Castor-oil hydraulic adhesive of the present invention and manufacture method belong to the polyurethanes technical field, are specifically related to the water conservancy project series tackiness agent and the manufacture method that adopt natural pure Viscotrol C to make.
Hydraulic binder is used for hydraulic engineering construction in a large number.Such as dam, aqueduct, water reservoir, hydro projects such as culvert, channel, pipeline, expansion joint filling in the construction, the joint of various pipelines is bonding, the erosion control of flow surface, the antiseepage of water delivery engineering, leakproof, hydraulic steel gate is anticorrosion etc., studying for a second time courses one has flunked of the various cracks in hydro project maintenance, leak particularly presses for a kind of excellent property, cheap jointing material, to satisfy the hydro project big area, to promote the use of on a large scale.About the water conservancy project jointing material, that uses for many years has petroleum pitch and a modified product thereof, coal-tar pitch and modified product thereof, and Resins, epoxy and modified product thereof also have various waterproofing unctions and some inorganic bonding materials.But these products, the poor performance that has, not enough as bond strength, high low temperature lower variation, embrittlement, aging or the like.Of non-ideal use, what have costs an arm and a leg, and big area is promoted and had any problem in hydro project.In sum, up at present, the high inexpensive comparatively ideal water conservancy project jointing material of matter that a kind of suitable hydro project is used also do not occurred, about the polyurethane adhesive class, 1940's just occurs in Germany.The U.S. and Japan are competitively studied afterwards, and even each advanced country of the world is all paid attention to.China's polyurethane adhesive material that began one's study from 1956.At present the polyurethane adhesive material is mainly used in the bonding of article under metal and the dry state conditions such as metal, metal and rubber-like, and the genus still of widely-used polyurethane adhesive jointing material is rare in water conservancy construction.Its reason mainly is this kind material feedstock costliness, cost height, be used in the hydro project expensive big, uneconomical, can not big area use and promote, domestic existing hexanodioic acid Viscotrol C polyester is made the product that raw material is made the polyurethane adhesive class, but the difference of this product and the present invention's castor-oil hydraulic adhesive is: the former hexanodioic acid Viscotrol C polyester is that hexanodioic acid and Viscotrol C synthetic modified castor oil are made raw material.The present invention then is directly as raw material system polyurethane adhesive with natural pure Viscotrol C.This important difference, make hydraulic binder manufacturing process of the present invention simple, cost than the former at double or several times ground reduce, hydraulic binder of the present invention so just can use in hydraulic engineering construction widely, having formed is a series of adhesive products of instigator's usefulness with the hydro project.Water conservancy project series tackiness agent pilot sample of the present invention is through strictness test and on probation in multiple hydro project, and performance is good, and price is low, and purposes is wide.Experimental result shows, is suitable for various hydraulic engineering construction needs fully.Coming as popularization will be to water conservancy, agricultural, building, water power, chemical industry, machinery, light industry, water transport, traffic, and remarkable economic efficiency and social benefit are widely brought in aspects such as life.We have carried out the relevant computer search of technical information both at home and abroad at technology contents of the present invention, and result for retrieval shows that the present invention is unique, and result for retrieval is referring to the appended search report of specification sheets of the present invention.
