Abstract
The invention provides a method for manufacturing one-component polyurethane waterproof coating. 44.4 percent of polyether 220 is added into a reaction kettle and stirred, and then 8.9 percent of polyether 330N is added, heated to 50 DEG C and stirred for 30 minutes. 97 percent of 9.1 percent TDI incorporation amount and 0.1 percent benzoyl chloride are added, and the mixture in the reaction kettle is heated to 80 DEG C and reacted for 150 minutes. 3.5 percent of talcum powder, 2.1 percent of light calcium carbonate, 0.4 percent of pigment and 3 percent of 9.1 percent TDI incorporation amount are added and stirred and reacted for 40 minutes, and the temperature is decreased below 50 DEG C. 4 percent of dibutyl phthalate, 0.25 percent of polyurethane defoamer and 0.25 percent of dibutyl tin dilaurate are added, stirred for 30 minutes and discharged. The invention has the following advantages of non-toxic to environment and human body, increased material performance, increased tensile strength and breaking elongation and improved waterproof effect.
Description
Technical field
The present invention relates to a kind of method of producing mono-composition poyurethane water-proof paint.
Background technology
At present, mono-composition poyurethane water-proof paint contains organic solution, contaminate environment, and be detrimental to health; Production unit requires harsh, has sudden and violent poly-possibility in process of production; Poor stability, viscosity increases when storing, and the influence construction is used; The need scene is added the waterproof paint of water, add entry water quality, the water yield all can the performance after the coating film forming be impacted, increase the waterproof effect labile factor.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective, a kind of method of producing mono-composition poyurethane water-proof paint is provided.
Technical scheme of the present invention is: a kind of method of producing mono-composition poyurethane water-proof paint is characterized in that: raw material weight %: polyethers 220 42-57; Polyethers 330N 7-10; Tolylene diisocyanate 8.5-11; Dibutyl tin laurate 0.2-0.45; Talcum powder 26-40; Light calcium carbonate 0-10; Pigment 0-5; Dibutyl phthalate 0-5.0; Polyurethanes defoamer 0.1-0.3; Benzoyl chloride 0.05-0.2, at first polyethers 220 is joined in the reactor, start stirring, add polyethers 330N, be warming up to 40-55 ℃ then, continue to stir 95-98% and the Benzoyl chloride that adds the TDI incorporation after 15-30 minute, compound in the reactor is continued to be warming up to 70-80 ℃ of reaction 120-180 minute, add talcum powder, light calcium carbonate, the 2-5% of pigment and TDI incorporation stirs and reacted 30-60 minute, be cooled to then and add dibutyl phthalate below 50 ℃ again, polyurethanes defoamer and dibutyl tin laurate, stirred 20-40 minute, and got final product discharging.
The present invention has the following advantages: to environment and body harmless, improve material property.Tensile strength and elongation at break improve, and improve waterproof effect.
Embodiment
Embodiment: 44.4% polyethers 220 is joined in the reactor, start stirring, add polyethers 8.9%330N, be warming up to 50 ℃ then, continue to stir 30 minutes, 97% and the Benzoyl chloride 0.1% that adds the 9.1%TDI incorporation, compound in the reactor is continued to be warming up to 80 ℃, reacted 150 minutes, and added talcum powder 3.5%, light calcium carbonate 2.1%, 3% of pigment 0.4% and 9.1%TDI incorporation stirs, and reacts 40 minutes, be cooled to then below 50 ℃, add dibutyl phthalate 4% again, polyurethanes defoamer 0.25% and dibutyl tin laurate 0.25% stirred discharging 30 minutes.
