Preparation method of pressure sensitive adhesive for polaroid protection film and protection film thereof

The invention discloses a preparation method of a pressure sensitive adhesive for a polaroid protection film and a protection film thereof. The pressure sensitive adhesive is prepared from the following raw materials in parts by weight: 10 to 40 weight parts of soft monomers, 5 to 15 weight parts of hard monomers, 2 to 6 weight parts of fluorine containing acrylate monomers, 0.8 to 3 weight partsof crosslinking monomers, 0.8 to 2 weight parts of vinylsilane, 0.5 to 2 weight parts of anti-static agents, 0.5 to 1.5 weight parts of initiators and 80 to 190 weight parts of solvents. The pressuresensitive adhesive can be directly covered on the surface of a polyester film; the additional addition of the curing agents and the anti-static agents is not needed; the adhesive layer resistance is 1010 ohm or less; the anti-static performance is realized. When the polaroid protection film adhesive layer is pasted on the surface of a polaroid, after the high-temperature and high-humidity tests for 500h, the protection film and the polaroid are tightly attached; no bubble bulges exist; no adhesive is remained when the protection film is torn away; defects such as hard shadow do not exist.

Polyester spandex super-quick-drying knitted fabric and processing method thereof

ActiveCN109056171AAchieve the effect of moisture absorption and quick dryingSoftSolvent-treatmentWeft knittingFiberPolyester
The invention discloses a polyester spandex super-quick-drying knitted fabric and a processing method thereof. The fabric is woven through a special weaving method with complete-extinction super-fine-denier polyester fibers with the filament number of 1.1-1.7 D and spandex fibers as the raw materials, and the close-fitting surface of the fabric is provided with dotted jacquard protrusions capableof guiding moisture in one direction. The processing method includes the steps of conducting weaving through a four-track single-side knitting machine, wherein four needles 1, 2, 3 and 4 are adopted;forming one loop through fourteen paths; conducting post-processing through polyester keratase. By means of the special weaving structure, the close-fitting surface has a small protrusion jacquard effect, the contact area of the close-fitting surface and a human body is reduced, and the movable friction coefficient is reduced; the dotted protrusion jacquard part making contact with skin has a one-way moisture guide function, and the water expanding capacity is improved. The complete-extinction super-fine-denier polyester fibers are selected as the raw material, the surface area of the fibers is increased, subsequent fibers have a certain anti-UV effect, and the knitted fabric has the advantages of being soft in color and luster, good in deep dyeing performance, high in textile drapability,strong in shielding performance and the like.

Halogen-free organic phosphorus-nitrogen expandable flame retardant and application thereof to flame-retardant paint

The invention provides a halogen-free organic phosphorus-nitrogen expandable flame retardant and an application thereof to flame-retardant paint. A preparation method of the halogen-free organic phosphorus-nitrogen expandable flame retardant comprises the following steps of: mixing 1 part by weight of phosphorus pentoxide with 1-3 parts by weight of phosphoric acid; under a stirring condition, adding 0.5-1 part by weight of a char forming agent and 2-4 parts by weight of a foaming agent in sequence into a mixture; adding an amine compound for neutralizing till the pH value is 5-7; and drying filter residues to obtain the halogen-free organic phosphorus-nitrogen expandable flame retardant. Anti-static flame-retardant paint is prepared by uniformly mixing 15-35 percent by weight of the halogen-free organic phosphorus-nitrogen expandable flame retardant into ordinary paint. The expandable flame retardant has a phosphorus-nitrogen synergistic effect. In the expandable flame retardant, phosphorus and nitrogen are taken as flame retardants of flame retardant elements. During burning of a high polymer containing the type of flame retardants, a uniform porous carbon foam layer can be formed on the surface; and the foam layer has the advantages of heat insulation, oxygen insulation, smoke inhibition, prevention of fused drops and good flame retarding and smoke inhibiting functions.

Antistatic wear-resistant non-woven fabric for manufacturing dust-free wiping paper and treatment method thereof

The invention discloses an antistatic wear-resistant non-woven fabric for manufacturing dust-free wiping paper and a treatment method thereof. The antistatic wear-resistant non-woven fabric is cellulose filament non-woven fabric of which the surface is coated with an antistatic coating, or spun-laced non-woven fabric formed by combining cellulose staple fibers and polyester staple fibers in different proportions, wherein the antistatic coating is a melamine resin coating combined with an antistatic agent with an active group. The treatment method comprises the following steps of: (1) preparing an antistatic coating solution; (2) coating the antistatic coating solution on non-woven fabric with a dip-coating process; (3) drying the non-woven fabric containing the antistatic coating solution; and (4) packaging the dried non-woven fabric in rolls to obtain the antistatic wear-resistant non-woven fabric. The antistatic wear-resistant non-woven fabric has the advantages of durable antistatic performance, high wear resistance, low probability of fiber breakage by hooking in use and fewer fallen fibers. The treatment process is simple; and the antistatic agent can be firmly combined on the surface of the non-woven fabric without polluting a product.
