Description
Technical Field
The invention relates to the field of defoamers, in particular to a novel polymer defoamer for waterproof paint and a preparation method thereof.
Background
The waterproof coating is widely applied in building decoration industry, such as house building, outer wall, indoor, urban road, tunnel, subway reservoir and the like. The waterproof coating material forms a coating film capable of preventing rainwater and underground infiltration, but the appearance of foam also has an effect on the performance of the waterproof coating material.
If the waterproof coating is foamed in the production process, the volume expansion of the surfactant is caused in the process of compatible stirring, and the utilization rate of blending equipment is reduced; the foam limits the stirring speed, so that the blending time of the waterproof paint is prolonged, and the filler and the dye cannot be fully wetted; if the foam is durable, the construction process can be influenced, so that the fluidity of the construction process is poor, and the conditions of surface defects, roughness, rupture during film formation and the like appear.
The waterproof paint defoamers used at present are various, but the defoamers have poor defoaming and foam inhibition and dilute and drift oil, when in use, after the emulsifier is separated from the surface of the defoamer due to certain reasons (such as water is added for dilution before coating), the water-insoluble defoamer is easy to cause shrinkage cavity and fish eye phenomena on the surface of a coating film.
Disclosure of Invention
The invention aims to provide a novel polymer defoamer for waterproof paint and a preparation method thereof, which are used for solving the problem of poor defoaming and foam inhibiting capability of the defoamer for the waterproof paint in the prior art.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
the novel polymer defoamer for the waterproof paint comprises the following components in parts by weight:
5-20 parts of oleic acid polyoxyethylene ether,
5-15 Parts of amino carbon nano tube,
10-40 Parts of heptamethyltrisiloxane,
0.5-1 Part of bimetallic catalyst DMC.
Further, the components in parts by weight are as follows:
10 parts of oleic acid polyoxyethylene ether,
15 Parts of amino carbon nano-tube,
20 Parts of heptamethyltrisiloxane,
0.5 Part of bimetallic catalyst DMC.
A method for preparing a novel polymer defoamer, comprising the following steps:
and step 1, weighing and mixing the oleic acid polyvinyl ether and the amino carbon nanotubes according to parts by weight, and stirring and reacting the mixture of the oleic acid polyvinyl ether and the amino carbon nanotubes for 1.8-3.5 hours at the temperature of 70-90 ℃ to obtain an intermediate reactant. In this step 1, the carboxyl end group of the oleic acid polyvinyl ether and the amino group of the amino carbon nanotube can be allowed to sufficiently contact and react, thereby introducing the carbon nanotube into the oleic acid polyvinyl ether.
And 2, weighing the bimetallic catalyst DMC and the heptamethyltrisiloxane according to parts by weight, adding the weighed bimetallic catalyst into the intermediate reactant obtained in the step 1, adding the heptamethyltrisiloxane in batches, and stirring and reacting for 1.7-2.2 hours at the temperature of 60-80 ℃ to obtain the novel polymer defoamer.
In the step 1, the stirring speed is 800-1000 r/min.
Further, in the step 1, the mixture of the two is stirred and reacted for 3 hours at the temperature of 80 ℃ to obtain an intermediate reactant.
In the step 2, the stirring speed is 1200-1500 r/min.
Further, in the step 2, the addition is completed by adopting a mode of dropwise adding heptamethyltrisiloxane and controlling for 30 minutes,
Further, in the step 2, stirring and reacting for 2 hours at the temperature of 70 ℃ to obtain the novel polymer defoamer.
The principle of the invention is as follows:
The invention adopts oleic acid polyoxyethylene ether as one of the raw materials, and the oleic acid polyoxyethylene ether is carboxyl end capped polyether. Polyether itself has good defoaming property as a defoaming agent, but is greatly affected by temperature, and when the temperature is increased or changed greatly, the defoaming effect is greatly impaired. The oleic acid polyoxyethylene ether selected by the invention has carboxyl groups with higher activity, and is easier to react with other groups for modification, so that the defect is overcome; and the emulsion has good emulsifying property, does not need to additionally add an emulsifying agent, and reduces the production cost.
The invention adopts amino carbon nano tube as one of the raw materials. The amino carbon nanotube is a substance with extremely high length-diameter ratio, molecules are rod-shaped, formed foam can be broken, and good foam breaking effect is achieved.
The invention adopts heptamethyltrisiloxane as one of the raw materials. The molecular structure of heptamethyltrisiloxane is as follows:
The heptamethyltrisiloxane has a series of advantages of low surface tension, small viscosity-temperature coefficient, high and low temperature resistance, oxidation resistance stability, weather resistance, corrosion resistance and the like, and the use of the heptamethyltrisiloxane modified polyether can obviously improve the defoaming capability and stability of the system; the methyl has extremely low surface tension, and the quantity of the methyl heptamethyltrisiloxane selected by the invention is large, so that the surface tension of a defoaming system can be obviously reduced, and the defoaming effect is achieved.
Therefore, compared with the prior art, the novel polymer defoamer prepared by the invention can obviously improve defoaming and foam inhibiting capability and has the advantages of low cost, good tolerance and stability.
