Problems solved by technology

[0005] The invention provides an acid-resistant non-curing waterproof coating and its preparation process. One of the purposes is to have acid-resistant performance, so as to solve the problem that the waterproof coating is prone to chemical reaction and deterioration in an acidic environment, resulting in attenuation of material properties and damage to the waterproof function. Another purpose is to solve the problem that some materials in the coating will freeze when the waterproof coating is used in a cold environment, resulting in the loss of the function of the waterproof coating, so as to achieve the effect of making the coating antifreeze

Embodiment 1

[0037] First aspect, such as Figure 2-5 As shown, the present invention provides an acid-resistant non-curing waterproof coating, and the raw material components are as follows in parts by weight: 40 parts of asphalt, 30 parts of sodium silicate filler, 10 parts of tackifying resin, 3 parts of aromatic hydrocarbon oil, polymerized chlorine 5 parts of aluminum iron, 5 parts of quartz powder, 1-5 parts of acid resistant agent, 1-3 parts of antifreeze agent, 1-2 parts of coating agent, and 1-2 parts of mold inhibitor.

[0038] In this embodiment, through the design of sodium silicate filler, the characteristics of strong cohesive force, high strength, acid resistance, heat resistance and alkali resistance of the sodium silicate filler make the cohesive force and strength of the waterproof coating , Acid resistance, heat resistance and alkali resistance are greatly improved, and the practical performance of waterproof coatings is increased. By setting aromatic oil, because aromat...

Embodiment 2

[0040] Such as Figure 2-5 As shown, on the basis of Example 1, the present invention provides a kind of technical scheme: preferably, after the acid-resistant agent is uniformly mixed and stirred by 70wt% of acid-resistant aggregate, 20wt% of powder and 10wt% of water glass solution, add an appropriate amount of The coagulant is mixed and made, the antifreeze agent is made by uniformly mixing 40wt% of slag powder, 6wt% of zeolite powder, 50wt% of cement, 4wt% of aluminum slag powder and an appropriate amount of water, and the coating agent is made of petroleum resin 60wt%, reducing 20wt% of second-line distillate oil, 10wt% of lubricating oil and 10wt% of low molecular weight polyethylene wax were mixed for 5 minutes under the environment of 120 degrees centigrade.

[0041]In this embodiment, by providing a coating agent, it is beneficial to the mixing between the various ingredients of the waterproof material, and the effect and speed of mixing are improved. By providing an ...

Embodiment 3

[0043] Such as Figure 2-5 Shown, on the basis of embodiment 1, the present invention provides a kind of technical scheme: preferably, fungicide is made of phenol 90wt%, copper sulfate 3wt%, sodium fluoride 3wt% and aluminosilicate mineral carrier 4wt% uniform Made by mixing, aromatic oil can be replaced with mineral oil or rubber oil according to the environment of use.

[0044] In this embodiment, the main filler of the antifungal agent is designed to be phenol, which has the functions of inhibiting mold growth and killing mold, and can prevent polymer materials from being corroded by fungi, maintaining good appearance and physical and mechanical properties. There is an antifungal agent in the coating to avoid the growth of mold in the waterproof coating, which will affect the appearance of the wall, making the waterproof coating suitable for applications in environments with strong mold growth, and can keep the surface of the coating film free from mold for a long time. In...

Abstract

The invention discloses an acid-resistant non-curing waterproof coating and a preparation process thereof, and relates to the technical field of waterproof materials, and the preparation process comprises the following steps: sequentially adding 40 parts of asphalt and 30 parts of a sodium silicate filler into a mixing machine, adjusting the temperature of an inner cavity of the mixing machine to 120-130 DEG C, and mixing for 3-5 minutes to obtain a first mixture; adding 5 parts of polyaluminum ferric chloride and 5 parts of quartz powder into a stirring barrel at the same time, controlling the stirring barrel to operate at the speed of 500-550 rpm for 10-12 minutes, and obtaining a second mixture. According to the invention, an acid-resistant agent is added, and the acid-resistant agent is mixed into the waterproof coating, so that the waterproof coating has relatively strong resistance to moisture and acidic substances, the problem that the coating is corroded by the acidic substances is avoided, and the problems that the material performance is degraded and the waterproof function is damaged due to the fact that the waterproof coating is extremely easy to generate chemical reaction in an acidic environment to be deteriorated are solved; and the applicability of the waterproof coating in an acid environment is improved.

Description

technical field [0001] The invention relates to a waterproof coating, relates to the technical field of waterproof materials, in particular to an acid-resistant non-curing waterproof coating and a preparation process thereof. Background technique [0002] Architectural waterproof coating is a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, it can form a tough waterproof coating film on the surface of the base layer after the volatilization of solvent or water evaporation or reaction curing. the general term for. Common types of waterproof coatings are polyurethane waterproof coatings, two-component polyurethane waterproof coatings, hydroxybutyl polyurethane waterproof coatings, one-component polyurethane waterproof coatings, polymer cement waterproof coatings, polymer emulsion waterproof coatings, asphalt waterproof coatings and modified Bituminous waterproof coatings, solvent-based bitumen waterproof coatings, water-based m...
