The invention relates to a nonwoven material, in particular to a diatomite-containing nonwoven material for sound absorbing cotton. The nonwoven material is made from, by weight, 100 parts of isotactic polypropylene, 12-15 parts of diatomite powder, 5-8 parts of texanol, 12-15 parts of dimethyl isophthalate, 7-9 parts of chlorcosane, 3-4 parts of dioctyl maleate, 1-2 parts of quartz powder, 10-12 parts of rice hulls, 5-7 parts of bamboo charcoal powder, 2-3 parts of dandelion, 1-2 parts of agrimonia pilosa, 1-2 parts of rheum officinale, 2-3 parts of seeds of Job's tears, 1-2 parts of honeysuckle stems and 4-5 parts of auxiliaries. The nonwoven material contains the diatomite powder, the quartz powder and the like, thereby being improved in mechanical properties and durable in use; due to the raw materials such as the rice hulls, the bamboo charcoal powder and Chinese medicinal herbs, the material is low in cost and has good sound absorption effect; flame retardation and water resistance of the material are improved due to the chlorcosane; after being subjected to multi-layer superposition, the nonwoven material can be made into the sound absorbing cotton, and the nonwoven material is simple in process and broad in application prospect.

The invention relates to a halogen-free flame-retardant nylon composite material, and belongs to the technical field of high polymer materials. The halogen-free flame-retardant nylon composite material is prepared from, by weight, 5-10 parts of caprolactam, 70-90 parts of PA66 resin, 5-15 parts of PA6 resin, 5-8 parts of silicon carbide, 6-11 parts of melamine pyrophosphate, 10-15 parts of acrylonitrile-butadiene-styrene copolymers, 5-10 parts of dioctyl maleate, 5-10 parts of di-n-hexyl azelate, 0.2-3 parts of modified nanometer rare earth oxides, 1-5 parts of microencapsulated halogen-free flame retardant, 0.1-0.6 part of accelerator, 0.1-0.5 part of activator, 0.1-0.5 part of stabilizer and 2-3 parts of lead fumarate. The halogen-free flame-retardant nylon composite material has the following performance indexes that the tensile strength is larger than 140 MPa, the bending strength is larger than 220 MPa, the impact strength of a cantilever beam notch is larger than 24 kj / m<2>, the melt flow index is larger than 16 g / 10 min, and the flame retardance reaches V-0(UL-94-1.6 mm). The high-temperature-resistant halogen-free flame-retardant nylon composite material not only has the barrier property, the dimensional stability, chemical resistance and high temperature resistance of high-temperature-resistant nylon, but also has the excellent impact resistance, flowability and flame retardant property.

The invention discloses an adhesive with strong adhering property. The adhesive with strong adhering property comprises the following raw materials: dioctyl maleate, nanometer smectite powder, styrene, hydroxyethyl methylacrylate, acrylate, crylic acid, sodium persulfate, allyloxy sodium, hydroxyalkyl sulphonate, pure benzene emulsion, sodium tripolyphosphate, sodium hypochlorite, argil, brown sugar, sodium laurate, starch, sodium hydroxide, borax, modified wood dust and water. The adhesive disclosed by the invention is stable in quality, strong in adhering property, excellent in connecting property, quick to dry and free from bubbling, and comprehensively improves various performances of corrugated cases; the modified wood dust is added, so that the damage of the water molecule to the adhesive can be reduced, and as a result, the water resistance of the adhesive is greatly improved; and the hydrophily is reduced, so that the adhesive has the characteristic of quick drying, and benefit is provided for using the adhesive in a high-speed tile line.
