Detailed Description
The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
An embodiment of the present invention provides: a production process and a formula of a liquid suspending agent comprise the following steps:
step one, adding water into a reaction kettle, then adding microcrystalline cellulose and stirring;
step two, adding silicone-acrylic resin emulsion into the stirred solution and stirring;
thirdly, adding 1000-2000 meshes of bentonite into the uniformly mixed emulsion and stirring;
step four, adding a PH value regulator, and continuously stirring the paste to adjust the PH value to 8;
step five, adding a dispersing agent and a preservative, and uniformly stirring;
step six, visual viscosity 1000+200 is qualified, the viscosity is regulated by adding water to be lower or the viscosity is regulated by adding microcrystalline cellulose solution to be lower, packaging and shipment are carried out after the viscosity is qualified, and an NDJ-1 rotary viscometer can be used for measuring the viscosity resistance of liquid and the absolute viscosity of liquid, wherein the NDJ-1 rotary viscometer is a novel instrument for measuring the viscosity resistance of liquid. The NDJ-1 rotary viscometer is widely applied to measuring the viscosity of various fluids such as grease, paint, food, medicine, adhesive and the like, and the selected rotor is screwed into a shaft connecting rod (screwed left for loading and screwed right for unloading). The lifting knob is rotated to enable the instrument to slowly descend, the rotor is gradually immersed into the measured liquid until the rotor liquid level mark and the liquid level are flat, and then the level is finely adjusted. The power is turned on, the pointer control rod is pressed down, the motor is turned on, the speed change knob is turned, the pointer control rod is loosened on the selected rotating speed gear, and the pointer can be read when stable, and generally about 30 seconds is needed. When the rotating speed runs in the 6 or 12 gear, the pointer can directly read after being stable; when the rotating speed is in the gear of 30 or 60, the pointer control rod is pressed down after the pointer is stable, the pointer rotates into the display window, the power supply is turned off to read, and when the numerical value pointed by the pointer is too high or too low, the rotor and the rotating speed can be changed, so that the reading is preferably about 30-90 grids.
The production formula of the liquid suspending agent comprises water, microcrystalline cellulose, silicone-acrylic resin emulsion, bentonite of 1000-2000 meshes, a PH value regulator, a dispersing agent and a preservative.
In the first step, the ratio of water to microcrystalline cellulose is 100: 1-3, water and microcrystalline cellulose need to be mixed, dissolved and stirred for 60 minutes, the microcrystalline cellulose is a linear polysaccharide substance combined by beta-1, 4-glucosidic bonds, and is a white, odorless and tasteless crystalline powder which is formed by hydrolyzing natural cellulose to extremely fine short rod-shaped or powder-shaped porous particles with limited polymerization degree (LODP) through dilute acid and can be free flowing, and the microcrystalline cellulose has special properties of low polymerization degree, large specific surface area and the like, and can stabilize foam and emulsion particularly in the high-temperature processing process; forming an ointment-like texture gel; improving the heat resistance of pectin and starch gel; improving the adhesion; replacing fats and oils and controlling ice crystal growth. Microcrystalline cellulose stabilizes emulsions and foams because microcrystalline cellulose adsorbs at the interface and reinforces the interfacial film.
The ratio of the stirred solution to the silicone-acrylic emulsion in the second step is 100: 5-10, mixing and stirring the stirred solution and the silicone-acrylic resin emulsion for about 30 minutes to uniformly mix, wherein the silicone-acrylic resin is copolymer emulsion of organic siloxane and acrylic ester. The environment-friendly coating base resin can be compounded with various organic resins according to a certain proportion, and has the advantages of weather resistance, environment friendliness, glossiness, small emulsion particle size, easy cleaning of the surface of the coating and stability.
The proportion of the emulsion and 1000-2000 mesh bentonite which are uniformly mixed in the step three is 100: 1-3, uniformly mixed emulsion and 1000-2000 mesh bentonite are mixed and stirred for about 60 minutes and homogenized, the main mineral component of the bentonite is montmorillonite, the content is 85-90%, and some properties of the bentonite are determined by the montmorillonite. Montmorillonite can be in various colors such as yellow green, yellow white, gray, white, etc. The water-saving type water-saving machine can be in compact block shape or loose soil shape, has a slippery feel when rubbed with fingers, and the small blocks are swelled for several times to 20-30 times after being added with water, are in suspension in water, and are in paste state when the water is small. The nature of montmorillonite and its chemical composition and internal structure are related, and the activated clay is an adsorbent which is made up by using clay (mainly bentonite) as raw material, making it undergo the processes of inorganic acidification treatment, water rinsing and drying, and its external appearance is milky white powder, and it is odorless, non-toxic, strong in adsorption property, and can adsorb coloured substances and organic substances. The adsorption performance can be reduced after the air is easy to absorb moisture and is placed for a long time. When the temperature is higher than 300 ℃, the crystallization water is lost, so that the structure is changed, and the fading effect is affected. The activated clay is insoluble in water, organic solvent and various oils, is almost completely soluble in hot caustic soda and hydrochloric acid, has a relative density of 2.3-2.5, and has very little swelling in water and oil.
The pH regulator in the fourth step can be organic acid or inorganic acid, alkali, neutralizer or buffer, and the pH regulator is also called pH regulator, acidity regulator or pH control agent, etc., and is used as chemical agent for regulating or maintaining pH. The acidity regulator may be an organic or inorganic acid, a base, a neutralizing agent or a buffer.
And step five, adding a dispersing agent and a preservative which are 0.3% of the total amount, wherein the dispersing agent is a surfactant which has two opposite properties of lipophilicity and hydrophilicity in molecules. The solid and liquid particles of inorganic and organic pigments which are difficult to dissolve in liquid can be uniformly dispersed, meanwhile, sedimentation and agglomeration of the particles can be prevented, amphiphilic reagents required for forming stable suspension can be formed, various substitutes of phenol such as biphenol, cresol and xylenol, cationic surface active substances, halogen and oxidants such as hydrogen peroxide and permanganate, aniline dye and acridine dye, heavy metal salts, alcohols and aldehydes are commonly used as medicines of preservative and disinfectant, and the preservative can inhibit microbial activity, prevent microbial infection and propagation and prolong the service life of the suspending agent.
