Problems solved by technology

However, the construction process of surface coating is relatively cumbersome. It often has a four-layer structure of sealer paint, putty layer, intermediate paint and top paint, and its environmental protection is poor; It is difficult for the harmful impurities it carries to penetrate into concrete. Its construction is simple and relatively environmentally friendly, but its price is high and its weather resistance is poor, so there are few engineering applications

preparation example Construction

[0070] The preparation method of organic modified silicate of the present invention is:

[0071] 3) Add organosilane to water to form a stable suspension, and slowly raise the temperature to 55°C;

[0072] 2) Turn on the stirring, control the rotation speed to 500r / min, and add the acidified tetraethyl orthosilicate to the above suspended matter for constant temperature reaction for 24h;

[0073] 3) filtering the obtained sedimentation product, washing with water for several times, and vacuum drying;

[0074] 4) Sintering the dried product at 220° C. for 4 hours to obtain an organically modified silicate product.

[0075] A kind of preparation method of novel concrete protection floor material, it comprises the following steps:

[0076] (1) Inject water, pH adjusting agent in batching tank (A), open disperser (i.e. stirring equipment), (for example or preferably adjust the rotating speed of stirring equipment to be 800-2000r / min, such as 1200r / min), Add silicate, stirring c...

Embodiment 1

[0088] Embodiment 1 (preparation example):

[0089] 1) Add 240kg of TQ-4 organosilane (structure shown in the following formula) from Changsha Institute of Chemical Industry to 800kg of deionized water, and slowly raise the temperature to 55°C;

[0090]

[0091] 2) Turn on the stirring, control the rotational speed to 200r / min, and add 180kg of tetraethyl orthosilicate from Changsha Research Institute of Chemical Industry after acidification treatment (500ml concentration of 35% hydrochloric acid added), and react at constant temperature for 24h;

[0092] 3) Reduce to normal temperature, filter the reaction solution, take the sediment and wash it with water for 3 times;

[0093] 4) Transfer the sediment into a crucible, put it into a constant temperature oven at 220° C. for sintering for 4 hours, and obtain an organically modified silicate product.

Abstract

A concrete terrace protective material includes, by weight, 150-280 parts of an organic modified silicate, 80-160 parts of an alkali metal silicate, 0.1-50 parts of a catalyst, 1-30 parts of a chelating agent, 5-50 parts of a pH conditioning agent and 500-1200 parts of water. The organic modified silicate is prepared, through a sol-gel method, from an organic silane containing hydroxy and / or carboxyl, and tetra(C1-C4 alkyl) orthosilicate in a composite manner. The material can improve surface strength, hardness and wear resistance of concrete; meanwhile, the material can effectively enable a surface of the concrete to be compact and can inhibit intrusion of water, oil and other corrosive substances, thereby obtaining a dust-free and compact integral body. The material can fundamentally alleviate or prevent corrosion of concrete, improve usage performance of the concrete and prolong service life of the concrete.

Description

Technical field: [0001] The invention relates to the field of floor coatings, in particular to a novel concrete protective floor material and a preparation method thereof. Background technique: [0002] Concrete has become the building structure material with the largest amount of application and the widest range of use. According to statistics, my country's concrete output in 2012 was as high as 1.2-1.3 billion m 3 , accounting for about 40% of the world's total output. However, its ubiquitous defects such as easy weathering and cracking, sanding, and non-wear resistance have always been a problem that has plagued people and has attracted widespread attention. Although there are many reasons for this phenomenon, it actually affects and reduces the use effect and life of the concrete floor. [0003] At present, the protection methods of concrete floors mainly include surface coating and silane impregnation. The surface coating includes two types of water-based coatings and...
