Dust-free chalk and manufacture method thereof

The present invention discloses a dust-free chalk and a manufacture method thereof. The dust-free chalk comprises a main ingredient and an auxiliary ingredient used as raw materials, wherein the main ingredient is composed of the following components in parts by mass: 10-16 parts of hardened oil, 12-18 parts of stearic acid, 3-6 parts of white beeswax, 1-3 parts of carnauba wax, 2-5 parts of propylene glycol, 1-2 parts of lecithin, 7-12 parts of fatty alcohol polyoxyethylene ether, 6-10 parts of epoxidized soybean oil and 0.1-0.5 part of paraben ester; and the auxiliary ingredient comprises the following components in parts by mass: 30-35 parts of titanium dioxide, 2-5 parts of nano calcium carbonate and 6-10 parts of mica powder. The manufacture method of the dust-free chalk comprises: firstly heating and stirring the main ingredient to obtain an emulsion, adding the auxiliary ingredient, stirring, then injecting the mixture into a mold for molding, condensing and demolding to obtain a finished product. The dust-free chalk has the advantages of good weathering resistance and moisture retention, writing lubricity, bright writing, moderate hardness, low possibility of breakage, no toxicity or odor and no dust generated during using and wiping processes. The selected materials are readily available soluble environmentally-friendly materials, and no pollutants are generated during the production process of the dust-free chalk.

Lightweight rubber material

The invention discloses a lightweight rubber material which is composed of the raw materials of, by weight, 3-4 parts of maleic anhydride, 0.2-0.6 parts of 8-10% sulfuric acid, 1-2 parts of an accelerator MZ, 26-30 parts of melamine, 5-8 parts of a 37% formaldehyde solution, 7-10 parts of urea, 6-10 parts of microcrystalline cellulose, 210-230 parts of chloroprene rubber S40V, 3-6 parts of white beeswax, 4-5 parts of magnesium enhancement powder, 0.7-1 parts of stannous octoate, 2-3 parts of polyurethane, 16-20 parts of Suzhou soil, 28-34 parts of light calcium carbonate, 4-7 parts of bitetradecenoic alcohol ester, 2-3 parts of wood creosote, 3-4 parts of an anti-aging agent DOD, 2-3 parts of sulfur, and 1-1.2 parts of isopropanol. According to the invention, with the crosslinking effect of maleic anhydride, microcrystalline cellulose forms a closer network structure in melamine resin formed by melamine, urea and formaldehyde, such that resin viscosity and tensile deformation resistance are well improved, and certain reinforcement and tackifying functions are performed in the rubber material. Therefore, flexure cracking resistance, hot-air aging resistance and stability are improved. The rubber finished product provided by the invention has the advantages of light weight, no toxic or harmful substance volatilization, easy transportation, and easy processing.

Environment-friendly viscosity reducer for printing ink and preparation method of environment-friendly viscosity reducer

The invention discloses an environment-friendly viscosity reducer for printing ink. The environment-friendly viscosity reducer is composed of the following raw materials in percentage by weight: 15-18% of Vaseline, 3-5% of white beeswax, 20-25% of resin oil, 15-18% of aluminum distearate, and 35-45% of linseed oil. The invention further discloses a preparation method of the environment-friendly viscosity reducer for the printing ink. The preparation method comprises the following steps: step 1, integrally adding linseed oil and resin oil into a reaction kettle according to formula data, and starting to stir when the temperature is increased to 88-95 DEG C; step 2, adding Vaseline and white beeswax into the reaction kettle, and continuously stirring; and step 3, uniformly mixing and stirring linseed oil and aluminum distearate to obtain a particle-free material, pumping the particle-free material into a high-level tank by a pump, slowly adding the particle-free material into the reaction kettle, continuously heating to 115-125 DEG C, carrying out heat preservation for 30-40 min, filtering, and taking out of the kettle. The prepared viscosity reducer can be added into ink to increasethe brightness of the ink, improve the wettability, improve the ink property, increase the printing speed and reduce the viscosity, and is environment-friendly and pollution-free.

Preservative-free moisturizing cream and preparation method thereof

The invention provides preservative-free moisturizing cream and a preparation method thereof. The preservative-free moisturizing cream is prepared from raw materials in percentage by weight as follows: 0.05%-5.0% of polyglyceryl-3 methylglucose distearate, 0.01%-1.0% of cetostearyl alcohol, 0.05%-6.0% of white beeswax, 1.0%-10.0% of shea butter, 1.0%-5.0% of squalane, 1.0%-5.0% of dimethicone, 1.0%-5.0% of caprylic or capric triglyceride, 0.01%-0.3% of sodium hyaluronate, 0.01%-0.3% low-molecular-weight sodium hyaluronate, 0.01%-1.0% of a thickening agent, 1.0%-5.0% of 1,2-pentanediol, 1.0%-8.0% of glycerin, 0.01%-5.0% of a herba portulacae extracting solution, 0.01%-1.0% of capryl glycol, 0.01%-1.0% of decanediol and the balance of water. According to the preservative-free moisturizing cream, the problem of water shortage and dryness of skin surface is solved, a breathable membrane is formed, rapid permeability can be realized better, moisturizing and moisture sustaining capabilitiesare improved from skin bottom, skin damage can be prevented and repaired, luster and elasticity are restored, and appropriate moisture required by skin can be intelligently adjusted according to humidity change of the external environment. Under the preservative-free condition, moisturizing activity of hyaluronic acid with two molecular weights can be kept better, and moisturizing effect of the moisturizing cream is improved.
