Abstract
The present invention relates to an environmental protection type water-base asphalt polyurethane water-proofing paint formed component A and component B, in which the component A contains (by weight portion) 50-95 portions of polyurethane prepolymer, 5-50 portions of modifying agent and 0.5-30 portions of adjuvant, and the component B contains 10-80 portions of asphalt emulsion and 5-50 portions of modifying material. Its preparation method includes the following steps: uniformly mixing modifying agent, adjuvant and polyurethane prepolymer, and packaging them to form component A; uniformly mixing asphalt emulsion and modifying material and packaging them to form component B; then mixing component A and component B according to the ratio of 1 : 0.1-1.2 so as to obtain the invented product.
Description
Environmental protection type soluble asphalt polyurethane water-proof paint belongs to building material field.
At present polyurethane water-proof paint mainly contains tar oil type, solvent pitch type, asphalt free water cure color-type three major types, and tar polyurethane waterproofing paint quality instability, ageing resistance are poor, seriously polluted, in being eliminated by pottery; Solvent pitch type polyurethane waterproof paint is because of containing a large amount of solvents, makes storage, transportation, construction safety poor reliability; Asphalt free water cure color waterproof polyurethane paint excellent property, pollution-free, construction safety convenience, but cost an arm and a leg, be difficult to be accepted by market.So the direction of current urethane development and research is energy-saving and environmental protection, easy construction, low, the aqueous product of price.
Purpose of the present invention is exactly that a kind of water-based, energy-saving and environmental protection, excellent property, the low desirable environmental protection type soluble asphalt polyurethane water-proof paint that is easy to apply of price will be provided.
Purpose of the present invention can realize by following measure:
A kind of environmental protection type soluble asphalt polyurethane water-proof paint, it is made up of A component and B component, and the A component is to be contained-base polyurethane prepolymer for use as of NH-C-O-key by intramolecularly, properties-correcting agent, auxiliary agent is formed; The B component is made up of bitumen emulsion and material modified institute; The weight content of A component is Polyurethane performed polymer 50-95 part, properties-correcting agent 5-50 part, and auxiliary agent 0.5-30 part, the weight content of B component is bitumen emulsion 10-80 part, material modified 5-50 part; Base polyurethane prepolymer for use as-NCO content is 1-20%, viscosity is 2000-8000CP; Properties-correcting agent is that lime, gypsum, cement, Wingdale, flyash, particle diameter are less than 0.05mm; Auxiliary agent is the tensio-active agent of HLB value at 8-18; Bitumen emulsion is stable greater than 6 months, and solids content is 20-70%; Material modified is polychloroprene latex, binary ethylene propylene rubber latex, Ethylene Propylene Terpolymer latex, chlorosulfonated polyethylene latex, chlorinated butyl latex and latex that can be miscible with bitumen emulsion; The ratio of A component and B component is 1: 0.1-1.2.
The preparation method of described environmental protection type soluble asphalt polyurethane water-proof paint is by following steps:
1. properties-correcting agent is ground to the fine powder of particle diameter less than 0.05mm in shredder, oven dry;
2. with properties-correcting agent, auxiliary agent and-NCO content is 1-20%, viscosity is that the base polyurethane prepolymer for use as of 2000-8000CP mixes, and is packaged into the A component;
3. be bitumen emulsion and material modified the mixing of 20-70% with solids content, be packaged into the B component.
4. with A component and B component by 1: the 0.1-1.2 mixed stirs and is the present invention.
The present invention compared with prior art has the following advantages:
1, the present invention has overcome existing tar polyurethane waterproofing paint quality instability, and ageing resistance is poor, with serious pollution deficiency;
2, the present invention has overcome solvent pitch type polyurethane waterproof paint because of containing a large amount of solvents, makes the deficiency of storage, transportation, construction safety poor reliability.
3, the present invention be water resistance is good, price is low, the wide pitch of originating combines with the color waterproof polyurethane paint of water cure, the premium properties that had both kept the water cure color waterproof polyurethane paint, reduced cost again, performance reaches (JC500) " polyurethane water-proof paint " acceptable end product, and production cost is lower than 1.4 ten thousand yuan/ton;
4, the present invention may be used on roofing, hypogee, surface structures, antiseptic project etc. and locates construction under the normal temperature.
Embodiment:

Polychloroprene latex 20
A∶B＝80∶20
The preparation method:
(1) lime is ground to particle diameter＜0.05mm, and oven dry and HLB value are that 12 tensio-active agent adds performed polymer together and stirs and be the A component.
(2) polychloroprene latex is added stir in the emulsified bitumen and be the B component.
(3) component A and B are stirred into environmental protection type soluble asphalt polyurethane water-proof paint by 80: 20 mixed.
Performance test reaches (JC500) " polyurethane water-proof paint " acceptable end product.
