The invention discloses an environment-friendly polyurethane adhesive which comprises a component A and a component B. The component A is prepared from the following raw materials in parts by weight: 10-50 parts of vegetable oil, 5-30 parts of polyether polyol, 0.1-0.5 part of a chain extender, 40-70 parts of solid filler, 0.1-1 part of an auxiliary agent and 5-20 parts of an adsorbent. And the component B comprises a curing agent. According to the environment-friendly adhesive, the polyether polyol with the hydroxyl value of 270-290 mgKOH / g, the viscosity of 40-140 mPa.s at the temperature of 25 DEG C and the K < + > value content smaller than or equal to 3 ppm is adopted, and the environment-friendly adhesive can have long-term tensile shear strength and peel strength. The epoxy group-containing silane coupling agent 3-glycidyl ether oxypropyl trimethoxy silane is adopted, so that the service life of the polyurethane adhesive can be prolonged, the influence of external environment humidity on the adhesive is avoided, and the long-term peel strength and tensile shear strength of the adhesive are maintained.

An adhesive film for metal terminal, which is to be interposed between a metal terminal electrically connected to an electrode of a power storage device element and a power storage device packaging material for sealing the power storage device element, wherein the adhesive film for metal terminal comprises a laminate comprising at least an acid-modified polyolefin layer for forming a metal terminal-facing surface and a polyolefin layer for forming a power storage device packaging material-facing surface, and a ratio of arithmetic surface roughness RaA (µm) of the metal terminal-facing surface of the acid-modified polyolefin layer to arithmetic surface roughness RaB (µm) of the power storage device packaging material-facing surface of the polyolefin layer satisfies the relationship: RaA / RaB > 1.2.

This invention relates to the field of multilayer curable base film technology, specifically to the online coating of polyester optically curable base films and its preparation method. This invention overcomes the problem in existing technologies where the adhesion and optical performance of the curable base film cannot be simultaneously achieved. First, this invention obtains core-shell structured functional particles by modifying in-situ polymethyl methacrylate with nano-silica; second, it obtains modified PET by melt blending optical-grade PET chips; finally, it melts the functional particles and modified PET to obtain an anti-adhesion masterbatch, prepares a composite base film through three-layer co-extrusion and biaxial stretching, coats it with a functional coating liquid, cures it stepwise to form a curing layer, and then heat-sets it to obtain the optically curable base film. Through base film modification, functional particle core-shell design, three-layer co-extrusion structure, and the synergistic effect of coating and process, this invention produces a polyester optically curable base film that combines high optical performance and good coating adhesion, applicable to release protection in the electronics field, decoration in the home appliance field, and other fields.

The invention discloses a gap reflecting film for a photovoltaic module and a preparation method thereof.The reflecting film comprises a base material layer, a bonding layer located below the base material layer and a reflecting layer located above the base material layer, a plurality of microstructures formed through imprinting are arranged on the reflecting layer in an array mode, and the microstructures are strip-shaped triangular prism structures which are continuously arranged in parallel; the bottom surfaces of the strip-shaped triangular prism structures are connected to the surface of the reflecting layer in parallel, and the top edges of the strip-shaped triangular prism structures protrude out of the surface of the reflecting layer. Different from an existing scheme which adopts a three-layer structure of a base material, a microstructure layer and a reflecting layer to realize reflection, the reflecting function is directly realized through the base material and the reflecting layer, and the strip-shaped triangular prism microstructure is directly prepared on the aluminum-plated or silver-plated reflecting layer by using an imprinting-wet etching process; the problem of low adhesive force between the ultraviolet glue and a base material can be effectively avoided; the strip-shaped triangular prism microstructure is obtained by directly etching the aluminum-plated reflecting layer, pinholes do not exist, and the reflecting efficiency is higher.
