Abstract
The invention discloses a double-component polyurethane water-proof paint for a ship. The double-component polyurethane water-proof paint is formed by mixing a material A and a material B, wherein the material A is prepolymer which is synthesized from polyalcohol and excess polyisocyanate; and the material B consists of the following materials in percentage by weight: 50 percent of curing agent, 20 percent of chain extender, 20 percent of auxiliary agent and 10 percent of filler. The double-component polyurethane water-proof paint has the advantages of high tensile strength, high adaptability to deformation of a base layer, superior low-temperature performance and the like.
Description
Technical field
The invention belongs to the boats and ships construction field, relate in particular to a kind of waterproof paint peculiar to vessel.
Background technology
At present, in the boats and ships construction, be crucial link for the regional WATER REPELLENT of boats and ships cabin life; Because the structure and the functional performance in boats and ships cabin life zone self, it is poor that existing waterproof paint exists in construction the distortion adaptive faculty of basic unit, a little less than the low-temperature performance; The little deficiency that waits of tensile strength, in addition, the waterproof effect of existing waterproof paint is undesirable; Leave seam easily, repair very inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of not only tensile strength big, strong to basic unit's distortion adaptive faculty, low temperature performance excellent, and also water resistance is strong, and seam is not stayed in easy construction, repairs to be easy to double-composition polyurethane waterproof paint peculiar to vessel.
A kind of double-composition polyurethane waterproof paint peculiar to vessel; It is mixed by first material and second material; Wherein the first material is that the second material is made up of polyamines or polyhydric solidifying agent, chainextender, auxiliary agent and filler with polyvalent alcohol and excessive POLYMETHYLENE POLYPHENYLISOCYANATE synthetic performed polymer.
Wherein the raw material weight component of first material is 50% polyvalent alcohol and 50% excessive POLYMETHYLENE POLYPHENYLISOCYANATE; Wherein polyvalent alcohol is that 40% polyglycerol ether, 40% W 166 and 20% glyceryl ester are formed; POLYMETHYLENE POLYPHENYLISOCYANATE be 50% 2; The 4-tolylene diisocyanate and 50% 2, the mixture of 6-tolylene diisocyanate.
The preparation of first material: in 1 liter of flask of whisking appliance, reflux exchanger, tap funnel and TM is housed, add polyglycerol ether, W 166, glyceryl ester and softening agent in proportion, logical nitrogen, agitator; About heat temperature raising to 40～45 ℃, begin to drip a certain proportion of 2,4 toluene diisocyanate and 2; The 6-tolylene diisocyanate slowly is warming up to about 80～85 ℃, in 1 hour, dropwises; Under this temperature, continue to keep reaction about 2 hours, i.e. discharging.
The raw material weight component of above-mentioned second material is 50% solidifying agent, 20% chainextender, 20% auxiliary agent and 10% filler; Solidifying agent be by 60% 3; 3'-two chloro-4; 4'-diaminodiphenyl-methane and 40% W 166 are prepared from, and chainextender is that diethylammonium toluene methylamine, auxiliary agent are mixed by 30% skimmer, 20% promotor, 30% flow agent and 20% anti-settling agent; Filler is to be mixed by the lime carbonate of 30% talcum powder, 30% perlite 30% and 10% carbon black.
The preparation of second material: earlier in proportion 3,3'-two chloro-4 add W 166 in the 4'-diaminodiphenyl-methane, are heated to 120 ℃, and cool to room temperature obtains solidifying agent, in solidifying agent, adds chainextender, auxiliary agent and filler, and stirring gets final product discharging.
The scope of application of the present invention: the life zone of boats and ships cabin, toilet etc.
Consumption: 2～3kg/ ㎡.
Method of use:
(1) base treatment is cleaned out mortar, dust, the foreign material of substrate surface, and basic unit must be smooth, solid and dry;
(2) priming; First material of the present invention, second material and thinner are pressed 1: (1.5～2): 1 weight ratio is mixed; Utilize whisking appliance that mixture is stirred after the mixing; Utilize round brush that mixture is evenly spread upon on the substrate surface, needed dry 4～24 hours can carry out the construction of subsequent processing behind the priming paint;
(3) be coated with the waterproof material; First material of the present invention and second material are pressed 1: the weight ratio of (1.5～2) is mixed; Utilize whisking appliance that mixture is stirred after the mixing, utilize round brush that mixture is evenly spread upon on the bottom surface, treat that the first layer waterproof material on foot after; Can continue to be coated with more waterproof layer as stated above, until reaching specific thickness.
The present invention compared with prior art has following advantage:
1, tensile strength is big, and is strong to basic unit's distortion adaptive faculty;
2, low-temperature performance is strong, does not receive humidity and Influence of Temperature during construction;
3, good water-proof effect, seam is not stayed in easy construction, repairs easily.
Description of drawingsThe present invention does not have accompanying drawing.
