Embodiment

[0006] Embodiment: a kind of production process of roof waterproof paint, 1, take 5 parts of polyvinyl alcohol and add 95 parts of water, gradually heat up to 70-90 ℃, keep for 5-15 minutes, make the content after making polyvinyl alcohol fully dissolve and be 5% 2. Pass the waste rubber powder through a 40-60 mesh sieve, and get 20 parts for later use; 3. Add 0.4 part of surfactant and 0.6 part of diethylenetriamine to the prepared two spare raw materials and stir evenly for later use ; 4. Prepared polyvinyl alcohol solution, 20 parts of white latex, 0.6 parts of ethylenediamine and stirred evenly for later use; 5. 100 parts of polyether-terminated NCO prepolymer, 40 parts of dioctyl phthalate, PAPI 5 parts, shake evenly and set aside; 6. Fully mix 80 parts of raw materials prepared in 3 and 20 parts of raw materials prepared in 5 to make a base material; 7. Mix 80 parts of raw materials prepared in 4 with 20 parts of raw materials prepared in 5 Mix well to make a fabric; app...

specific Embodiment approach

[0008] Embodiment: 1, get polyvinyl alcohol 5kg, add water 95kg, heat up to 80 ℃, keep 13 minutes, polyvinyl alcohol is fully melted, make the polyenol solution that content is 5% standby; 2, get waste rubber powder 50 mesh sieve, take 20kg for later use; 3. Add 0.4kg of surfactant and 0.6kg of diethylenetriamine to the materials prepared in 1 and 2 and stir evenly for later use; 4. Mix the raw materials made in 1 with 20kg of white latex, ethylene diethylene triamine 0.6 kg of amine was stirred evenly for later use; 5. Take 100 kg of polyether-terminated NCO prepolymer, 40 kg of dioctyl phthalate, and 5 kg of PAPI, and stir it evenly for later use; 6. Prepare 50 kg of raw materials prepared in 3 and 5 20kg of raw materials are mixed uniformly to make base material; 7, 50kg of raw materials produced in 4 and 20kg of raw materials produced in 5 are mixed uniformly to make fabrics.

Abstract

The invention relates to a production process of a roof waterproof coating. 1. 5kg polyvinyl alcohol is taken, 95kg water is added, the temperature is raised to 80 DEG C to be continued to 13min, solution with 5 percent of polyvinyl alcohol is prepared untill the mixture is fully dissolved; 2. crumb rubber is taken to be sieved and about 20kg is reserved; 3. 0.4kg surfactant and 0.6kg diethylenetriamine are added in the material produced in 1 and 2 and evenly stirred to be reserved; 4. the material produced in 1 is evenly stirred with 20kg white emulsion and 0.6kg ethylenediamine to be reserved; 5. 100kg polyether type end NCO prepolymer, 40kg dioctyl phthalate and 5kg PAPI are evenly stirred to be reserved; 6. 50kg material produced in 3 and 20kg material produced in 5 are evenly stirred to produce bottom material; 7. 50kg material produced in 4 and 20kg material produced in 5 are evenly stirred to produce the coating. The invention has the advantages of strong adhesion, impact resistance and aging resistance.

Description

technical field [0001] The invention relates to a production process of roof waterproof paint. Background technique [0002] The architectural coatings currently used on building roofs contain harmful substances and pollute the environment; they have poor adhesion and are not firmly combined with buildings; Contents of the invention [0003] The purpose of the present invention is to overcome above-mentioned deficiency, a kind of roof waterproof coating production technology is provided. [0004] The technical scheme of the present invention is: a roof waterproof paint production process, characterized in that: polyvinyl alcohol, waste rubber powder, surfactant, polyether-terminated NCO prepolymer, dioctyl phthalate, white Latex, ethylenediamine raw materials, the prepared coating is divided into two kinds of primer and top coating, the primer is applied to the building surface, and the top coating is coated on the primer. [0005] The invention has the following advanta...
