Abstract

The invention relates to a paint composition taking physical property of the composition or effect generated by the composition as characteristics and a production method thereof, and in particular belongs to aqueous grease sealing paint and a production method thereof. The method adopts the technical proposal as follows: mixing and stirring water, polyurethane, acrylic modified latex, aqueous acrylic modified latex, an isocyanate firming agent, a lyophobic modified polyacrylate type dispersing agent, an alkyl polyoxyethylene ether rheological additive, an alkali-swelling latex type thickening agent, a non-ionic interface foam suppressor, an isothiazoles ketone mildew inhibitor and other materials; and filtering the mixture through a filter to obtain the paint composition. The paint has the advantages that the paint overcomes the defects of various aqueous paints in water resistance, oil resistance, adhesive force, hardness, scraping resistance and other aspects, and can save cost for raw materials and manpower, and is an excellent environment-friendly product.

Description

technical field [0001] The present invention relates to the coating composition characterized by its physical property or the effect produced and its manufacturing method, especially belongs to water-based sealant paint and its manufacturing method. Background technique [0002] Coatings are roughly divided into two categories: oil-based or water-based. Due to the excellent properties, mature technology and long-term use of oil-based coatings, they have been widely used and recognized. The continuous increase limits the use of oil-based paints, and people use water-based paints instead. In recent years, water-based paints have developed rapidly. In the prior art, water-based coatings are widely used in construction, furniture, etc. as primers, but water-based coatings have many shortcomings in terms of waterproof, oil-proof, adhesion, hardness, and scratch resistance, so they are difficult to be popularized and applied. Contents of the invention [0003] The object of the...
