The invention relates to a non-solvent type high-temperature resistant strippable protection ink and a preparation method of the ink. The ink comprises the following raw materials by weight parts: 55 to 65 parts of vinyl chloride-acetate copolymer, 35 to 45 parts of plasticizer, 0.2 to 0.5 parts of epoxy resin, 0.5 to 1 part of heat stabilizer, 1 to 2 parts of fumed silica, 0.3 to 0.5 part of toner, 0.6 to 1 part of flatting agent, 0.6 to 1 part of de-foaming agent, and 0.6 to 1 part of surfactant. The ink prepared by the invention uses the non-solvent formula, has no volatile substances in the printing and film-forming processes, and is of non-reaction type; and in addition, the film forming condition is simple and the property of the film is excellent.

The invention discloses an environment-friendly vegetable oil type ink and a preparation process thereof. The environment-friendly vegetable oil type ink mainly comprises the following raw materials by weight: 20-35 parts of a coloring agent, 3-5 parts of auxiliary agents, 30-48 parts of rosin-modified phenolic resin and 20-30 parts of a solvent, wherein the auxiliary agents are mainly composed of1-5 parts of an anti-friction agent, 0.5-2 parts of a drying agent, 0.5-3 parts of an anti-drying agent and 3.5-4.5 parts of other auxiliary agents, and the solvent is mainly composed of soybean oil,linseed oil and tung oil. According to the ink in the invention, resin with low solubility and medium and low viscosity is selected and used, and vegetable oil esters having performance similar to the performance of mineral oil are elected and used, so the ink of the invention overcomes the problem of slow fixation speed, poor printability, too hard ink properties, great colloidality and too large yield value of conventional ink, has rich color and good effect, and accords with the development trend and the green development concept advocated at present.

The invention discloses a formaldehyde-resistance odor-removing total-effect environmental-friendly waterborne wood white paint and a preparation technology thereof. The wood white paint comprises the following components in percentage: 25 to 30 percent of formaldehyde removing emulsion, 10 to 15 percent of core-shell pure acrylic acid emulsion and polyurethane modified acrylic acid emulsion, 3 to 5 percent of bamboo carbon powder, 1 to 3 percent of nano TiO2 photocatalyst, 15 to 25 percent of calcium carbonate and pigment and filler, 0.1 to 0.3 percent of delustering powder, 0.1 to 0.2 percent of antifoaming agent, 0.5 to 1.5 percent of dispersing agent, 0.2 to 0.5 percent of anti-sedimentation agent and 18 to 38 percent of water and auxiliaries. The preparation technology comprises the following steps of: firstly adding the core-shell pure acrylic acid emulsion and the polyurethane modified acrylic acid emulsion into a dispersing cylinder and dispersing at an intermediate speed; then uniformly adding micron active bamboo carbon powder; after dispersing for 15 to 30 minutes at a high speed, adding the formaldehyde removing emulsion, scratch resistance wax additive, the water, thedispersing agent, the delustering agent, the antifoaming agent, the anti-sedimentation agent and other components; after dispersing for 40 minutes at an intermediate speed, sampling and detecting thefineness and the viscosity of a finished product; and carrying out filtering, canning and packaging on the finished product.

The invention provides a microbial deodorant. The microbial deodorant comprises the raw materials of bacillus subtilis, enterococcus faecalis, photosynthetic bacteria, nitrifying bacteria and lactic acid bacteria. After the microbial deodorant is sprayed in wastewater or filth, microorganisms grow and multiply by exponential multiples, antioxidants such as NH3, H2S and NO2 are produced within a short period of time to resist the survival and reproduction of rot fungi, and a biodegradation layer is formed on the surface of the filth, so that gaseous NH3 is not escaped, furthermore, the microorganisms can also decompose harmful components such as NH3, H2S and methyl mercaptan to achieve the effect of quick deodorization, no pungent odors are produced during the use process, the microbial deodorant can be in contact with human bodies or animal skin and is non-toxic and harmless, and specially cleaning is not required; the microorganisms are decomposed into carbon dioxide, water and non-toxic cell residues after pollutants are eaten, so that secondary pollution is avoided. The deodorant forms microbial cell membranes on the pollutants such as bottom surfaces, objects and waterway equipments after being used for a long term to achieve a sustained and stable deodorization effect.

The invention discloses a polylactic acid composition used for 3D printing, and a preparation method thereof, and belongs to the technical field of 3D printing material. The polylactic acid composition used for 3D printing comprises, by weight, 40 to 50 parts of PLA, 40 to 50 parts of a hydrophilic material, 5 to 10 parts of a polyurethane material, and 5 to 10 parts of nanometer grade active carbon; the polyurethane material is prepared through polymerization of dihydroxy terminated PLA, a dihydroxy terminated hydrophilic material, and a cyanate ester compound, or is prepared through polymerization of dihydroxy terminated PLA and a diisocyanate group terminated hydrophilic material. The raw materials of the polylactic acid composition are mixed at the above ratio, and are subjected to granulation so as to obtain the 3D printing material product. The 3D printing material is capable of realizing full color printing wherein aqueous dye is adopted for spray dyeing, is high in mechanical strength, and no pungent smell is generated in printing process.

The invention provides a transparent electrical bushing which is characterized by being prepared from the following components in parts by weight: 100 parts of polyvinyl chloride, 1.0-2.0 parts of anorganic tin stabilizer, 0.6-1.6 parts of an internal lubricant, 0.2-2.0 parts of an external lubricant, 1.0-2.0 parts of a processing aid, 3.0-6.0 parts of a modifier, 1.0-1.5 parts of DOP, 0.2-1 partof a pigment and 0.002-0.006 part of a whitening agent. The pipe has a relative density of 1.35 to 1.55 and is high in corrosion resistance, which is 1.5 to 2 times that of conventional pipes, and good in transparency; the surface and the inner wall of the PVC wire pipe are smooth and have no concavo-convex sense, and the smooth inner wall greatly reduces the resistance when a wire is pulled; theperformance is 2 to 2.5 times that of the conventional pipes. The transparent electrical bushing emits green smoke when burned, has a high flame retardant coefficient and does not produce a pungent odor.
