Description

Reaction type seal primer with super-strong salt-efflorescence-resistant performance and preparation method thereof
Technical Field
The invention is suitable for indoor and outdoor building inner and outer walls, newly-made cement surfaces, newly-made putty layers, wall surfaces with efflorescence and coastal areas with heavier salt content, is a reaction type seal primer with super-strong efflorescence alkali resistance, has excellent adhesive force, can keep good adhesive force with various harsh substrates, simultaneously has excellent efflorescence alkali resistance, can meet the requirement of being applied to construction on newly-made cement and putty, has good seal performance on the alkalinity of the substrates, and is a reaction type seal primer capable of thoroughly solving the efflorescence of the wall surfaces and a preparation method thereof.
Background
Ordinary concrete is silicate, and when meeting air or water vapor in a wall body, hydrolysis reaction occurs, generated hydroxide radicals are combined with metal ions to form hydroxide with low solubility (the chemical property is alkaline), when the temperature rises, water vapor evaporates to separate the hydroxide out of the wall body, and the hydroxide is separated out on the surface of concrete cement along with the gradual evaporation of water, so that the hydroxide accumulates day by month, and the original decorative coating or paint and other objects are jacked up and do not adhere to the wall surface any more, so that whitening, peeling and falling occur, and the process is called as 'saltpetering'. The paint film of the whiskering local paint film is damaged, cannot play a role in protecting and decorating, is easy to mildew and fade, and can prevent the bearing capacity of the wall body from being reduced after a long time, so that the potential safety hazard of the structure is caused.
Meanwhile, in coastal areas, wall efflorescence often occurs due to large moisture and salt content, and the wall is difficult to prevent efflorescence by using common alkali-resistant primer. Therefore, in order to solve the problem of wall efflorescence, the used primer has the following characteristics: 1. the reinforced base layer plays a role in reinforcing and protecting the looser inner and outer wall putty; 2. the water absorption of the base layer is reduced and homogenized, and the problems of uneven finish paint film, color difference and the like caused by large and uneven water absorption of the inner wall putty are prevented; 3. the adhesive force of the coating on the putty is improved, the primer generally has lower viscosity, slightly lower surface tension, fine particles and good fluidity, and is easy to permeate into the surface of the putty to generate good adhesive force; 4. the sealing effect is that the primer can penetrate into the putty layer to fill capillary pores to react with alkali, and harmful substances such as salt, alkali and the like in the putty can be effectively prevented from migrating to the surface of the paint film along with water evaporation, so that the surface effect of the finish paint and the overall performance of the paint film are influenced.
