Embodiment 1

[0057] This example is used to illustrate the emulsified wax composition provided by the present invention and its preparation method.

[0058] Raw materials are weighed according to parts by weight, and the specific formula of raw materials is as follows: No. 56 semi-refined paraffin wax (Yanshan Petrochemical production) 25% by weight, No. 70 microcrystalline wax 3.0% by weight (Jingmen Petrochemical Company production), emulsifier (Henan Provincial Road Pure Chemical Technology Co., Ltd., AG-105 cationic paraffin emulsifier, mainly containing lauryltrimethylammonium chloride) 2.0% by weight, calcium stearate 0.1% by weight, water 69.9% by weight.

[0059] Select paraffin wax, microcrystalline wax, emulsifier and stabilizer according to the above proportions, put them into a melting tank for heating, heat to 110°C and keep warm until they are completely melted to form a uniform mixture, and transport the resulting mixture to an emulsification tank , add hot water heated to 8...

Embodiment 2

[0064] This example is used to illustrate the reference emulsified wax composition and its preparation method.

[0065] Prepare the emulsified wax composition according to the method of Example 1, the difference is that the specific formula of the raw materials is as follows: No. 56 semi-refined paraffin wax (produced by Yanshan Petrochemical) 25% by weight, No. 70 microcrystalline wax 3.0% by weight (produced by Jingmen Petrochemical Company) , Emulsifier (Jiangsu Haian Petrochemical Plant, A-105 nonionic paraffin emulsifier, main component is fatty acid polyoxyethylene ester) 2.0% by weight, calcium stearate 0.1% by weight, water 69.9% by weight. An emulsified wax composition product is obtained. The obtained emulsified wax product is analyzed, and the obtained results are shown in Table 1.

Abstract

The present invention relates to an emulsifying wax composition, a preparation method and applications thereof, wherein the emulsifying wax composition comprises 15-50 wt% of paraffin, 0.1-5 wt% of microcrystalline wax, 1-6 wt% of a paraffin emulsifying agent, and 40-80 wt% of water. According to the present invention, the emulsifying wax composition has advantages of small average particle size, and good storage stability, and the water absorbing thickness swelling rate of the product obtained by adopting the emulsifying wax composition as the water repellent agent is low.

Description

technical field [0001] The invention relates to an emulsified wax composition, a preparation method thereof and the application of the emulsified wax composition as a waterproofing agent. Background technique [0002] Emulsified wax is a kind of homogeneous fluid containing wax and water made by paraffin wax under the action of external mechanical force by means of directional adsorption of emulsifier. According to the type of surfactant used, it can be divided into cationic emulsifying wax, anionic emulsifying wax, nonionic emulsifying wax and zwitterionic emulsifying wax. [0003] The preparation process of emulsified paraffin wax is relatively simple, and can be divided into four types according to the adding method of emulsifier (generally surfactant): (1) agent in water method, that is, the emulsifier is directly dissolved in water, and the wax is added under vigorous stirring. (2) The agent in oil method, that is, the emulsifier is dissolved in wax, and then water is ...
