Abstract
The invention discloses a formula and a preparation process of vinyl epoxy phosphate polyurethane which is simple in process and good in use effect. The vinyl epoxy phosphate polyurethane is prepared from the raw materials in parts by weight: 74 parts of acrylic acid, 400 parts of epoxy E44, 98 parts of phosphoric acid and 50 parts of hexamethylene diisocyanate. The preparation process comprises the following steps of enabling epoxy E44 and hexamethylene diisocyanate to react for 8 hours in a reactor with the constant temperature of 50 DEG C, then, heating to the temperature of 110 DEG C, adding acrylic acid (containing a polymerization inhibitor), carrying out heat preservation until the acid value is decreased to about 30mg/KOH, cooling to the temperature of 100 DEG C, adding phosphoric acid, and carrying out heat preservation for 3 hours, thereby preparing a vinyl epoxy phosphate polyurethane monomer. The vinyl epoxy phosphate polyurethane has the advantages of simple process, good high- and low-temperature resisting effects and the like and is beneficial to large-scale popularized use.
Description
Technical field
The present invention relates to a kind of formula of vinyl epoxy phosphoric acid urethane, especially a kind of technique be simple, the formula of vinyl epoxy phosphoric acid urethane that result of use is good and preparation technology thereof.
Background technology
Require that temperature is higher than 5 DEG C at present during vinyl epoxy phosphoric acid urethane construction both at home and abroad, humidity, not higher than 85, uses limitation comparatively strong, affects result of use.
Summary of the invention
For solving the problem, based on above-mentioned background, the invention provides formula and the preparation technology thereof of a kind of vinyl epoxy phosphoric acid urethane that a kind of technique is simple, result of use is good, its raw material form and ratio as follows: 74 parts, vinylformic acid, epoxy E44 400 parts, phosphatase 79 8 parts, hexamethylene diisocyanate 50 parts.
Its preparation technology is as follows: by epoxy E44 and hexamethylene diisocyanate in the reaction kettle for reaction of 50 DEG C of constant temperature after 8 hours, be warming up to 110 DEG C to add vinylformic acid (containing stopper) insulation and be down to about 30mg/KOH to acid number, be cooled to 100 DEG C and add phosphoric acid be incubated 3 hours i.e. vinyl epoxy phosphoric acid urethane monomer processed.
It is simple that this patent has technique, the advantages such as high-low temperature resistant is effective, is conducive to large-scale promotion and uses.
