Description

High-temperature-resistant and aging-resistant polyurethane material and preparation method thereof TECHNICAL FIELD

[0001] The present application belongs to the technical field of polyurethane materials, and particularly relates to a high-temperature-resistant and aging-resistant polyurethane material and a preparation method thereof. BACKGROUND

[0002] Polyurethane coatings are a high-performance coating system, which is known for its unique chemical structure and excellent physical properties. It is composed of polyurethane resin as the main film-forming material, supplemented by pigments, fillers, additives and organic solvents (or water) and the like. Modern polyurethane coatings increasingly use low VOC (volatile organic compounds) or solvent-free technology, which reduces environmental pollution and harm to the human body, and thus are widely used in many fields.

[0003] The coating protection and decoration of glass and glass products have wide demand and application in industry and daily life. The coating protection and decoration of glass and glass products refers to the process of coating a specific glass coating on the surface of a glass substrate to form a film layer after curing. In industrial environments, such as kiln, high-temperature equipment window and other fields, the glass surface needs to withstand high temperature. High-temperature-resistant coatings can protect the glass from deformation or rupture due to high-temperature baking.

[0004] The existing polyurethane material has the following problems when coated on the surface of glass: (1) insufficient interfacial bonding force: the chemical bonding or physical adsorption between the polyurethane and the glass surface may not be strong enough, resulting in poor adhesion between the coating and the glass substrate, especially in the case where the glass surface is not properly pretreated (such as cleaning, roughening), which may cause peeling and peeling of the coating during use; (2) hygrothermal aging and environmental stress cracking: in an environment with high humidity or large temperature changes, the polyurethane coating may expand due to moisture absorption and the coefficient of thermal expansion between the glass substrate does not match, resulting in stress concentration and thus cracking of the coating; (3) ultraviolet aging: the polyurethane material exposed to sunlight, especially ultraviolet radiation, may undergo photodegradation, resulting in discoloration, chalking and cracking of the coating, reducing its protective performance and aesthetics, and the existing technology generally adds ultraviolet stabilizers to improve.

[0005] Based on the technical defects in the prior art, it is of great application prospect and market value to develop a polyurethane material that can simultaneously solve the above problems.

[0006] SUMMARY

[0011] Further, the hydroxyl-terminated polybutadiene has a hydroxyl value of 0.71-0.80 mmol / g. Tianyuan Aviation Material (Yingkou) Technology Co., Ltd.

[0012] Further, the polyether polyol is a compound of polyether polyol A, polyether polyol B and polyether polyol C in a mass ratio of 1.6-1.8:1:0.3-0.6; wherein the polyether polyol A is a polyether triol with a hydroxyl number of 535 mgKOH / g; the polyether polyol B is a polyether diol with a hydroxyl number of 36-39 mgKOH / g; and the polyether polyol C is a polyether diol with a hydroxyl number of 153-188 mgKOH / g.

[0013] Further, the phenolic resin has a free phenol mass percentage content of 10-14%. Hebei Zetian Chemical Co., Ltd., model 2127-1.

[0014] Further, the epoxy resin has an epoxy equivalent weight of 210-230 g / mol. Shandong Pinshang New Material Co., Ltd., Phoenix brand WSR6101 epoxy resin.

[0015] The polyurethane material is modified by polyurethane, and supplemented with phenolic resin and epoxy resin, so that the temperature resistance and moisture resistance of the polyurethane material are improved. The polyurethane is prepared by using polyether polyols with different hydroxyl numbers, polyether diols and polyether triols, and polybutadiene with terminal hydroxyl groups, forming a more complex three-dimensional crosslinked network structure, adjusting the microphase separation state of the hard segment and the soft segment of the polyurethane, and optimizing the microphase structure; supplemented with epoxy resin and phenolic resin, a highly crosslinked three-dimensional network structure is formed through curing reaction, and an interpenetrating network structure is formed between them, which can improve the interface properties, and under the synergistic effect, the temperature resistance and moisture resistance of the polyurethane material are improved. The inventors accidentally found that under this condition, the aging resistance of the polyurethane material is also improved.

[0016] Further, the preparation method of the modified solid filler is:

[0017] (1) mixing hollow ceramic microbeads, silicon dioxide and mica stone powder with a mass ratio of 1:1.4-1.8:0.3-0.7 to obtain a mixed filler;

[0018] (2) dispersing the mixed filler in 50-60wt% ethanol aqueous solution, adding 2-4wt% silane coupling agent KH550, and reacting at 60-70℃ for 3-5h, centrifugal separation, drying to obtain the modified solid filler.

[0022] The glass surface is relatively smooth, resulting in that the adhesion of the polyurethane material on the glass surface is not ideal. The inventors attempt to add silica to improve the mechanical bonding force of the polyurethane material and the glass, but the effect is not ideal. The inventors select three fillers for compounding and modification, and the obtained modified solid filler can improve the adhesion of the polyurethane material on the glass surface. The analysis is that the three fillers are mixed to improve the compactness of the coating, and a better mechanical engagement with the glass surface is formed, and a porous structure can be formed after the coating is dried, thereby increasing the actual contact area of the coating and the glass surface; the modified composite filler can adjust the rheological property of the coating, and can react with the silicate network on the glass surface to form a chemical bond, thereby greatly enhancing the adhesion. The inventors accidentally found that the hardness of the polyurethane material is improved under this condition.
