Abstract
The present invention provides the polyurethane elastomeric compositions of a kind of solvent-free, fast reaction, highly-acidproof, is a component by the prepolymer that polysulfide rubber and di-isocyanate reaction obtain；Epoxy-modified end hydroxy butadiene and amino chain extender, catalyst, mill base, acid resistance filler and other auxiliary agents form polymer polyol component.And by the way of fast spraying curing type, achievees the purpose that construction is simple, improves construction efficiency, obtained product has excellent acid resistance, while safety and environmental protection, and is able to maintain preferable physical mechanical property and service life.
Description
Technical field
The present invention relates to the fast spraying curing type modified polyurethane material used under a kind of acidic environment, it is suitable for changing
In the case of the contact high concentrated acid such as work, tank field, mine and pipeline, acid pond (concentration is greater than 30%) (sulfuric acid, hydrochloric acid, phosphoric acid etc.)
Container protection against acids coating, and there is construction is simple, high efficient construction.
Background technique
Spraying polyurethane technology is applied after low pollutions such as high solid coating, water paint, photocureable coating, powdery paints
After dress technology, a kind of novel free of contamination environmentally friendly construction technology.With solvent-free, rapid curing, construction efficiency it is high,
Thickness applies not sagging, the characteristics such as insensitive to temperature and humidity, physical property is superior, has extensively in the fields such as waterproof, anti-corrosion, wear-resisting
Using.
Spraying polyurethane combination material is divided into two kinds of components of A, B, separately includes isocyanate component and polymer polyatomic alcohol group
Point.High temperature and pressure impacting type mixed spraying equipment is generallyd use when construction.Rapid shaping, it is thick that primary construction can reach design
Degree, and can be formed in any curved surface spraying.Coating is continuous, fine and close, seamless.
Chemical industry, mine, the industries such as hydrometallurgy can be related to a large amount of acidic materials such as salt in process of production
Acid, sulfuric acid etc..For various reasons, these acidic materials leak and corrode the risks such as building, structures, it is therefore desirable to resistance to
Acid medium protects it.Commonly used at present has the materials such as acidproof brick, acid-resisting concrete, acid resistant adhesive mortar.The present invention
It has the advantage that compared with prior art
1, form of construction work: the prior art mainly uses manual brushing mode, and construction efficiency is low, and the material solidification time is long
(curing time is greater than 2 hours).The present invention uses two-component mechanically spraying, and construction efficiency greatly improves, and curing rate is fast
(solidifying within 10 seconds), production efficiency greatly improves.
2, the feature of environmental protection: prior art material contains solvent based on solvent type in material, has pollution to environment.The present invention
It is 100% solid content material, it is environmentally protective without any volatile material.
3, acid resistance: traditional technology, which mainly passes through, adds the corrosion resistance that various fillers improve material, and acid resistance
Difference cannot be resistant to the corrosion of acidic materials for a long time.The present invention mainly based on acid-proof resin, supplemented by acid resistance filler, passes through material
Modified, acid resistance is excellent, and acidproof service life greatly improves.
Summary of the invention
The present invention provides the spraying expediting setting type modified polyurethane material used under a kind of acidic environment and its preparation side
Method.The Material Manufacturing Process is simple, construction is simple, environmental protection, and obtained product strength is high, elasticity, good toughness and has excellent
Acid resistance and long-term service life.It can be used for the surfacecti proteon of the acidic environment of chemical industry acid pond, mine, pipeline etc.,
And other containers for containing high concentrated acid solution.
The present invention solves the used specific technical solution of its technical problem:
A kind of fast spraying curing type modified polyurethane acid resisting material and preparation method thereof, it is characterised in that change including (component A)
The synthesis and (B component) epoxy-modified end hydroxy butadiene polyether polyol, amino chain extender of property base polyurethane prepolymer for use as, color
The mixing of slurry, catalyst, acid resistance filler, auxiliary agent etc..
Using individually packaging, when site operation, uses professional flush coater with volume ratio 1:1's for component A and B component of the present invention
Ratio impingement mix curing molding.
Appellation A of the present invention, B component are intended merely to the convenience in statement.
Further:
The synthetic method of (component A) modified polyurethane prepolymer described in 1. are as follows: in parts by weight, isocyanate-monomer 10-
50 parts, liquid polysulfide rubber is 20-80 parts, 0.2-2.5 parts of catalyst.Liquid polysulfide rubber is added three mouthfuls according to the number of calculating
Flask, temperature are heated to 100 degree or so, and vacuum dehydration 2 hours, temperature was reduced to 40 degree or so, was slowly added to quantitative isocyanide
Acid esters adds for 30 minutes, and after reaction 30 minutes, catalyst is added, and temperature is increased to 65 degree, is stirred to react 4-6 hours, cools down cold
But it discharges.
The synthetic method of epoxy-modified end hydroxy butadiene polyether polyol described in 2.: end hydroxy butadiene is taken
40-90 parts, in three-necked flask, are heated to 100 degree or so, and then vacuum dehydration is cooled to room temperature, epoxy resin 20-60 is added
Part, it is stirred to react, is stirring evenly and then adding into 0.1-2 parts of catalyst, reaction heating continues to be warming up to 95 degree, instead after temperature is stablized
4-6 hours are answered, cooling discharging.
(B component) 3. described in the preparation method comprises the following steps: in parts by weight, the epoxy-modified terminal hydroxy group polybutadiene of above-mentioned synthesis
40-60 parts of alkene polyether polyol, 5-20 parts of amino chain extender, 2-8 parts of mill base, 0.2-1.5 parts of catalyst, acid resistance filler 5-30
