The invention discloses a method fro preparing a novel all-natural anticorrosive mildew-proof preservative for foods. The method comprises the following steps: uniformly mixing the following components in parts by weight: 10-20 parts of mixed extract of raw materials such as garlic, shaddock ped and cinnamon bark, 1-3 parts of nisin, 1-3 parts of D-sodium erythorbate, 1-3 parts of sodium lactate, 10-20 parts of ethanol and water, and obtaining a natural anticorrosive mildew-proof preservative of pickled foods. The anticorrosive preservative is safe, non-toxic, good in broad-spectrum bacteriostatic and bactericidal performance and excellent in anticorrosive mildew-proof effects; the preservative has an effect of expelling insects, is readily available in raw materials and simple in production process and is widely applied to corrosion prevention of vegetables pickled in soy sauce, pickled vegetables, pickled Chinese cabbage, pickles, recipe, thick broad-bean sauce and other foods.

The invention discloses a mildew-proof soaking device for a sofa wooden board. The mildew-proof soaking device comprises a motor, a speed reducer, a rotary shaft, a solution placing slot and a plurality of wooden board placing slots, wherein a hole is formed in the solution placing slot; a bearing is arranged in the hole; the rotary shaft passes through the bearing and is connected with the speed reducer outside the solution placing slot; the speed reducer is connected with the motor; the wooden board placing slots are uniformly and symmetrically mounted in the axial direction of the rotary shaft arranged in the solution placing slot; openings are formed in the bottoms of the wooden board placing slots; slot bottom plates are hinged on side walls on the bottom of the wooden board placing slots; and a plurality of water inlets are formed in the side walls of the wooden board placing slots. The mildew-proof soaking device is simple in structure, a mildew-proof solution is placed into the solution placing slot, the mildew-proof solution soaks the rotary shaft, and the motor rotates to slowly rotate the rotary shaft through the speed reducer, so that the wooden board placing slots in the rotary shaft can be alternatively soaked into the mildew-proof solution, and the soaked wooden board is taken out of the mildew-proof solution and is dried in air by blowing via an air blower in an accelerated mode repeatedly by many times, and therefore, the soaked wooden board has better corrosion and mildew resistance.

The invention provides a kind of antisepsis and antifungal agent for bamboo wood materials, which is mainly obtained by adding zinc-containing compounds, copper-containing compounds and cationic surfactants to the substrate; the present invention uses bamboo vinegar, wood vinegar and grass vinegar as main components, Biological (chemical) wood preservatives are prepared by compounding water-insoluble inorganic compounds, and nitrogen-containing compounds of ammonia, ammonium salts or amines can also be added to increase its solubility. The beneficial effects of the invention are mainly reflected in: strong loss resistance (loss rate less than 2%), low hygroscopicity, no blooming phenomenon, low toxicity, good anti-corrosion and anti-mildew effect, and can also be used for discoloration treatment of wood and bamboo.

The invention relates to a high-performance sand wall paint and a preparation method thereof, which is characterized in that it comprises the following raw materials in parts by weight: 15-30 parts of base material, 60-80 parts of natural colored sand, and 3-6 parts of film-forming aid , 0.1-0.5 parts of wetting agent, 0.5-2 parts of titanium dioxide, 0.1-0.3 parts of dispersant, 0.1-0.5 parts of anti-corrosion and anti-mold agent, 0.1-0.5 parts of multi-functional additives, 0.05-0.2 parts of defoaming agent, 0.01-0.2 parts of thickener, 10-15 parts of deionized water, the base material includes a mixture of pure acrylic emulsion and styrene-acrylic emulsion, and the weight ratio of pure acrylic emulsion and styrene-acrylic emulsion is 1-2:1. The components of the sand wall-shaped paint of the present invention are scientifically compatible, and the prepared paint has good comprehensive performance, less dosage, low use cost, high strength, compact surface, convenient construction, good stain resistance, high mechanical construction efficiency, and coating decoration The effect is good, the texture is strong, the color is rich, and the imitation stone effect is good.

The invention relates to a preservative for concrete admixture and a preparation method thereof. The raw materials include the following components in parts by weight: 10-23 parts of bactericidal components, 10-20 parts of antibacterial components, and 5-20 parts of intermediate active components. 15 parts, 8 to 13 parts of anti-precipitation components. The present invention has a small amount in the concrete admixture, and when mixed into liquid admixtures such as water reducer, slump retaining agent, and wet-mixed mortar additive, it will not separate out, has good compatibility with the concrete admixture, and is anti-corrosion and mildew-proof. Good effect, can effectively inhibit the growth and reproduction of microorganisms such as yeast, bacteria and mold. When the pH value of the concrete admixture is 2-7, the bactericidal effect of the preservative of the present invention is the best, and the preservative of the present invention will degrade naturally in concrete and has no adverse effect on the environment.
