The present invention relates to the field of fabricated exterior walls, in particular to a fabricated steel structure exterior wall, comprising a support assembly, a connection assembly, an exterior assembly of a steel structure exterior wall panel and an interior assembly of a steel structure exterior wall panel, the connection assembly , the outer component of the steel structure exterior wall panel and the inner component of the steel structure exterior wall panel are all arranged inside the support component. Through the provided connection components, insert the limit slide bar into the slot, press the steel structure wall panel to the inside of the groove, and slide the limit slide bar to the inside of the limit chute, so that the steel structure wall panel and The connection between the support components is completed, and the set dividing protrusions are located at the four corners of the wall panel, which can make the alignment of the wall panel more accurate and convenient during installation. During installation, the bolts can be used to align the wall panel with the wall panel. The board is fixed, which greatly improves the work efficiency.

The invention belongs to the technical field of fine chemicals, and specifically relates to a method for preparing alkyd resin based on trimellitic anhydride rectification heavy raffinate, the reaction of trimellitic anhydride rectification heavy raffinate, monohydric alcohol and catalyst in a molten state, through a water separator Separate the water phase to obtain the monohydric alcohol esterification product of trimellitic anhydride rectification heavy raffinate. After the acid value meets the requirements, lower the temperature, add organic solvent and water, stir and mix evenly, then stand still, drain the water phase, and recover the reaction product through the rectification separation column. Solvent and monohydric alcohol, start the vacuum pump, distill out the reacted polyhydric alcohol in the reaction liquid, add organic solvent, stir and mix evenly to obtain the alkyd resin product. The preparation process of the present invention is simple and has high productivity, which is conducive to the batch preparation of high-performance alkyd resins. The polybasic acid in the heavy residual liquid of trimellitic anhydride rectification is used as a raw material to reduce the production cost of the product alkyd resin, improve economic benefits, and make the product have a strong price advantage.

The invention is environmentally friendly, non-toxic, harmless to human body, non-polluting to the environment, and bright in color.

The invention relates to an ecological wall film board and a thermal transfer printing preparation method, which is characterized in that: it is made of a high-curing sub-transfer coating and a curing agent through thermal transfer curing, and the high-curing sub-transfer coating and the curing agent The mass percentage is 3-5:1; the high-curing sub-transfer coating is composed of silicon micropowder, kaolin, muscovite powder, magnesium aluminum silicate, polymer cellulose, dispersant, wetting agent, defoamer, anti-corrosion Composed of agent and clean water, the weight percentage of each material component is: silicon micropowder 25-30%, kaolin 15-25%, muscovite powder 15-25%, magnesium aluminum silicate 0.2-0.3%, polymer fiber Primer 0.1-0.2%, preservative 0.15-0.25%, dispersant 0.4-0.6%, wetting agent 0.15-0.25%, defoamer 0.6-0.8%, and the balance is clean water; the mass percentage of each material component The sum of the contents is 100%. It has outstanding substantive features and significant progress such as low film forming temperature and adapting to the fast-paced transfer printing needs of mechanical equipment.

The present invention relates to a water-base fast-drying high gloss ambient crosslinking nail paint resin and a preparation method thereof. The composition components comprise n-butyl acrylate, n-butyl methacrylate, methyl methacrylate, styrene, methacrylic acid, diacetone acrylamide, adipic dihydrazide, ammonium persulfate, emulsifier OP-10, emulsifier sodium dodecyl sulfate, ammonia and deionized water. After the resin is prepared into water-base nail paint (also called nail polish), the content of volatile organic compounds is less than 20 gram per liter, the nail paint does not contain harmful substances, such as triphenyl, formaldehyde and the like, has no poison and no smell, is harmless to human bodies and has no pollution to the environment, short drying time, strong adhesion and water resistance, high brightness of the paint film, bright color and strong color retention, as the solid content of the resin is high, the paint film thickness of thin painting is guaranteed, the surface is full and smooth, and the resin is an environmental-friendly product which can protect human health and is a substitute of nitro-nail paint which is commonly used in market currently.

The invention discloses a method for preparing alkyd resin by taking TMP rectified heavy residual liquid as a raw material. The method is characterized by being conducted according to the following steps that the raw material-TMP rectified heavy residual liquid raw material, polybasic organic acid, an acid catalyst and a water carrying agent are added into a reactor or added with an antioxidant, wherein an acid antioxidant or a phosphite antioxidant is adopted as the antioxidant; the temperature of the reactor is slowly increased, stirring starts after the raw material is fused, a constant-temperature reaction is conducted for 4-6 h after the temperature reaches a set reaction temperature of 200 DEG C to 240 DEG C; sampling is conducted every 55-65 min, the acid value of a reaction system is measured, and an alkyd resin prepolymer is obtained; the acid value of the reaction system needs to be controlled to be smaller than 5 mgKOH / g, and after the acid value meets the requirement, heating stops at once; after the temperature is lowered to the set 100+ / -5 DEG C, an organic solvent is added, after the liquid is stirred and mixed to be uniform, discharging is conducted, and then the alkyd resin product is obtained. The method is beneficial for protecting the environment and preparing the alkyd resin which has the cost performance advantage and the high performance in a batched mode.
