3results about How to "Both thermal insulation" patented technology

This invention relates to the field of fiber technology and discloses an antibacterial and heat-insulating fiber based on thermal insulation materials and its preparation method. By surface-modifying inorganic antibacterial and heat-insulating hollow titanium dioxide microspheres with polythiophene and polybutadiene, an antibacterial and heat-insulating material with good antibacterial and heat-insulating properties is prepared. This material is then introduced into polypropylene chips along with a reactive quaternary ammonium salt antibacterial agent, methacryloyloxyethyltrimethylammonium chloride, and extruded via a melt reaction. The resulting fiber possesses both excellent heat insulation and long-lasting antibacterial properties, while also improving the fiber's comfort.

The utility model relates to composite roof technical field discloses a kind of color steel sheet composite roof, including multiple wooden piles 1, multiple wooden piles 1 top is erected with same wood girder 2, multiple wood side beam 3 are extended in wood girder 2 two sides, steel beam 5 is erected above wood girder 2, steel beam 5 is connected with wood girder 2 top by steel prop 6, wherein multiple steel side beam assemblies are symmetrically arranged in steel beam 5 two sides, tile roof is laid on wood side beam 3, and color steel sheet is laid on steel side beam assembly.The utility model leaves gap between girder and steel beam, forms air layer, and further makes through the staggered lap joint design of tile roof and color steel sheet, cooperates the flow guiding effect of air layer, to form air convection between tile roof and color steel sheet space, forms certain ventilation condition, this unique design not only realizes double waterproof function, more effectively blocks heat conduction and sound propagation, and has the excellent performance of heat insulation and sound insulation.

The utility model discloses a multilayer reinforced protection type packing carton, including the box body, the top of box body is provided with the box cover, the box body and box cover all include white cardboard layer, the surface fixedly connected with corrugated paperboard layer of white cardboard layer, one side of corrugated paperboard layer is provided with first function layer, first function layer includes honeycomb paperboard layer and EVA bubble cotton layer, one side of first function layer is provided with second function layer. The utility model discloses through setting up corrugated paperboard layer, utilizes the mechanical characteristic of corrugated structure, promotes the compression strength and the bending resistance of packing, supports the stacking weight, disperses external pressure, reduces local stress deformation, especially suitable for heavy object packing or transportation scene, through setting up honeycomb paperboard layer, the honeycomb three -dimensional structure provides excellent compression resistance and impact resistance, effectively absorbs external impact force, light in weight but high in strength, can promote the protection effect under the premise of not increasing packing weight, is suitable for transportation scene.
