Description

A kind of production method of TZ-MPA spray polyurea waterproofing coating

Technical field

The present invention relates to a kind of architectural waterproof material.

Background technology

A kind of elastomer substances that at present traditional spraying polyurethane is generated by isocyanate component (A component) and resin Composition (R or B component) reaction.Isocyanic ester both can be aromatic, also can be aliphatic.B component wherein must be made up of oil terminal hydroxy group resin (for example dibasic alcohol, trivalent alcohol, polyhydroxylated polymer polyvalent alcohol etc.) and terminal hydroxy group (aromatic series or aliphatics) chainextender, in the terminal hydroxy group resin, must contain the catalyzer that is useful on the raising reactive behavior.And shortcomings such as ubiquity solvent contamination in the conventional spray paint technology, thin thickness, sagging, set time are long.

Summary of the invention

The objective of the invention is to be, a kind of production method of TZ-MPA spray polyurea waterproofing coating is provided.

The technical solution used in the present invention is: a kind of production method of TZ-MPA spray polyurea waterproofing coating, with A component: PPG-2000, MDI, NCO; The B component: Amino Terminated polyether(ATPE) JEFFAMINE@T-5000, DETDA-diethyl toluene diamine, pigment, kaolin (1250 order), potter's clay are that 1: 2 ratio is manufactured according to weight ratio:

The A component:

The isocyanic ester input is equipped with in the reactor of agitator, thermometer, charging opening, nitrogen inlet, be heated to 50-60 ℃, after treating its complete fusion, add the polyether glycol after complete drying is purified, at 80 ± 5 ℃ of insulation reaction 3-4 hours, electricity consumption was the stable back discharging of volumetry test NCO%, filtration, airtight package storage.

The B component:

An amount of amino-polyether of exsiccant color stuffing adapted is ground on three-roll grinder, then ground slurry is dropped in the reactor, add remaining Amino Terminated polyether(ATPE), amino chainextender and other auxiliary agents again, 100-110 ℃ of following vacuum hydro-extraction, when moisture content was lower than 500ppm, cooling was filtered the back packed for standby use with 200 mesh sieves.

The invention has the beneficial effects as follows:

(1) do not contain catalyzer, fast setting can spray mo(u)lding on arbitrary surface, inclined-plane and vertical surface, does not produce the sagging phenomenon, the 5s gel, and 1min can reach walking intensity.

(2) insensitive to moisture, moisture, be not subjected to the influence of envrionment temperature, moisture during construction.

(3) 100% solid contents do not contain any volatile organic matter (VOC), and are environmentally friendly.

(4) can spray or pour into a mould by 1: 1 volume ratio, once Shi Gong thickness range can overcome in the past the repeatedly disadvantage of construction from hundreds of microns to several centimetres.

(5) use suite of equipment, easy construction, efficient is high.
