The invention relates to the technical field of barrier films, and particularly discloses an ultrahigh water and oxygen barrier film for a vehicle-mounted OLED display product. The thickness of the ultrahigh water and oxygen barrier film is 15-35 microns, and the ultrahigh water and oxygen barrier film sequentially comprises a first antistatic layer, a first barrier layer, an OLED working layer, a second barrier layer, a polyethylene glycol terephthalate layer and a second antistatic layer, the thickness ratio of the first antistatic layer to the first barrier layer to the OLED working layer to the second barrier layer to the polyethylene glycol terephthalate layer to the second antistatic layer is (2-4): (2-4): (8-16): (2-4): (4-8): (2-4). The first barrier layer and the second barrier layer are prepared from the following raw materials in parts by mass: 1-2 parts of cholesterol, 5-15 parts of phospholipid, 1-2 parts of N-acryloyl glycinamide, 1-2 parts of graphene oxide, 0.01-0.1 part of a photoinitiator, 1-2 parts of hydroxypropyl methyl cellulose, 1-5 parts of fluorinated ethylene propylene, 1-5 parts of tetra-n-butyl titanate and 1-2 parts of a surfactant.

The invention discloses a textile ultrasonic low liquid-carrying rate roller, comprising a first box body and a dust-absorbing and softening device. The invention realizes efficient spreading and ultrasonic dyeing of textile fabrics by arranging a first flattening roller, a water tank, an ultrasonic device, a guide roller, a second flattening roller, a third flattening roller, a first roller and a second roller, so as to realize uniform dyeing of the fabrics. The first roller and the second roller can realize intermediate force due to their internal hollow structures, so as to reduce the liquid-carrying rate of the fabrics. The dust-absorbing and softening device is arranged, that is, under the transmission of the first toothed disc and the second toothed disc, the convex plate arranged on the outside of the rotating roller can cooperate with the receiving roller to realize intermittent transmission of the fabric, so as to prolong the subsequent dyeing time of the fabric. The dust-absorbing structure and the heating structure arranged on the outside of the moving component can be cooperated to perform dust-absorbing and heating softening activities on the fabric, so as to assist in enhancing the dyeing uniformity of the fabric, so as to greatly enhance the dyeing quality and uniformity.

The invention belongs to the technical field of side slope drainage, and particularly relates to a road shoulder and side slope collaborative drainage system based on concrete precast blocks, which comprises a roadbed, a side slope positioned on the roadbed, a road shoulder positioned at the top of the side slope, and a drainage ditch positioned at the bottom of the side slope, net-shaped frame units and torrent groove units are arranged on the slope surface of the side slope at intervals, and the torrent groove units penetrate through the slope top to the slope bottom; the net-shaped frame unit is fixed on a slope surface through an anchoring part and is connected with the torrent groove unit; the drainage ditch is formed by connecting a plurality of groove units; compared with the prior art, the construction difficulty is reduced through modular components, the construction efficiency is improved, and meanwhile peak regulation and storage and ecological maintenance can be achieved.

The utility model provides a grease-proof corrugated board suitable for cold-chain logistics, which sequentially comprises a grease-proof coating, a low-temperature-resistant PLA (polylactic acid) lamination layer, a wavy buffer layer, a rebound filling layer, a degradable PE (polyethylene) preservative film layer, an oil-resistant coating, a honeycomb board layer, an oleophobic activated carbon non-woven fabric layer and a high-density corrugated paper inner layer from outside to inside, and the rebound filling layer is correspondingly arranged in a corrugated gap of the wavy buffer layer in a filling manner. High low temperature resistance and grease permeation resistance are realized.

The invention discloses bionic intestinal villus aerogel as well as a preparation method and application thereof. The aerogel comprises an aerogel skeleton with a layered structure, and a bionic villus structure is grafted on the layered structure; the invention relates to a carbon-based composite material which comprises the following components in parts by mass: 1-1.5 parts of a carbon source, 1.5-2.5 parts of a cross-linking agent, 0.2-0.5 part of a catalyst and 0.5-1 part of a phytic acid-polyethyleneimine ligand. The preparation method comprises the following steps: adjusting a polyethyleneimine ligand aqueous solution to be acidic, adding a phytic acid aqueous solution, stirring to generate white precipitate, washing and freeze-drying to obtain a ligand, and grinding to obtain powder; the preparation method comprises the following steps: dissolving a carbon source, sequentially adding a cross-linking agent and a catalyst, stirring to form a gel precursor, adding ligand powder, stirring, and directionally freeze-drying to obtain the composite material. The bio-based electrolyte ligand is grafted into an aerogel system with a layered structure through an in-situ polymerization method to construct the bionic intestinal villus type composite aerogel, so that the flame-retardant and heat-insulating properties are enhanced, and meanwhile, the antibacterial property is remarkably improved.

The present invention relates to a probiotic agent for slowing down blood coagulation and its application in preparing a sanitary napkin for preventing side leakage. The strain in the probiotic agent for slowing down blood coagulation is composed of Lactobacillus acidophilus. Lactobacillus acidophilus LA88 strain and Lactobacillus rhamnosus Lactobacillus rhamnosus LRa05 strain composition. The two strains can cooperate with each other, promote each other, and synergize in the effect of slowing down blood coagulation. They are further used to prepare blood absorption products such as sanitary napkin products, which can prolong the penetration and absorption time of the sanitary napkin absorption layer, promote the absorption effect, and prevent blood leakage. At the same time, the above two strains also have excellent inhibitory effects on common reproductive tract pathogens and can maintain a healthy colony environment of the reproductive tract. In addition, both bacteria are probiotics, the product is highly safe, and it is not easy to produce resistance.
