Provided herein are multi-layer composite construction materials which are suitable as an external insulating layer on a dwelling, which includes homes, office buildings and other installations. The composite constructions of the invention comprise an insulating layer which is typically abutted or adhered to an outside surface of a dwelling, often to the exterior of a foundation or basement wall near the ground line. A composite according to the invention resists damage and abrasion from normal activities, which may include landscaping activity and normal wear and tear experienced by external building surfaces.

Gas-permeable 100% reinforced thermosetting polyester film material for the manufacture of pest control applicators, comprising a grid including a base of polyester yarn overlain with top and bottom layers of polyester fibers, and an aqueous-based paste of the same polyester filling the spaces between the grid yarn and fibers and having a melting point lower than the grid yarn and fibers polyester. A pest control applicator is formed of such film material, filled with pest control agent reactive with water to release a fumigating gas, and after reaction of the pest control agent with air humidity, the applicator is immersed in water to deactivate residial pest control agent.
摘要:
A method wherein a thin card web which contains meltable synthetic fibers as well as natural fibers is processed into a thicker web of fleece. The synthetic fibers are initially melted to prestrengthen the web. Then the web is saturated with the appropriate fluid finishing agent for making the web flame-resistant and the like and this web can then be readily dried on a screen drum dryer. It is at this point that the web layers are accumulated into a proper fleece in a cross layer unit which transfer the end product to a heat treatment assembly for heating to effect vulcanization, curing or setting of the synthetic fibers.
摘要:
A blend of high-molecular and a low-molecular organic material contains the high-molecular organic material in a proportion smaller than that of the low-molecular organic material, and has a three-dimensionally continuous network skeleton structure formed by the high-molecular organic material. The structure preferably has an average cell or mesh diameter not exceeding 500 microns. The removal of the low-molecular organic material from the blend gives a functional porous material consisting of the high-molecular organic material. The replacement of the low-molecular organic material in the blend with a solid or liquid, or a mixture thereof, gives a functional composite material containing the solid or liquid, or their mixture in the network skeleton structure.

A leather-like foam sheet for vacuum forming, which comprises:(1) a transparent of semitransparent colored polyurethane elastomer film layer,(2) a colored polyurethane elastomer film layer,(3) a polyurethane adhesive layer,(4) a thermoplastic resin foam layer (optional),(5) a thermoplastic resin sheet layer, and(6) a thermoplastic resin foam layer.The foam sheet of the present invention has excellent resistance and forming properties and a high-grade leather-like appearance and a soft feeling to the touch similar to those of natural leather and is useful for a trim material of a car and for furniture and other miscellaneous goods having leather-like appearance, touch, and other properties.
摘要:
An apparatus and method for coating a substrate with plastisol and depositing pebbles into the ungelled coated plastisol is presented. A powder containing fusible particles compatible with the coated substrate and the pebbles is then deposited by at least one rotary silk-screen printing frame and thereafter a heat treatment is carried out in an oven or with infrared lamps at a temperature below the distortion temperature of the substrate in order to set the deposited materials.
摘要:
A stiffening material composed of 30 to 80 weight percent filler particles and 70 to 20 weight percent binder which is thermoplastically deformable and has melt-adhesive properties in the temperature range of 50.degree. to 80.degree. C., wherein the filler particles are plastic particles or particles having plastic surfaces with a particle size distribution of 50 to 500 microns.
摘要:
The invention relates to a waterproof, weather-resistant and substantially non-stretching textile, which is a substantially non-stretching, tension-resistant cloth coated with a weather-resistant synthetic substance. According to the invention, a glass-fiber cloth is first impregnated with polyurethane or polyacrylate in order to form a continuous coating-base for a weather-resistant synthetic substance, which is polyimide or fluorinated or chlorinated polyurethane, polyacrylate or polyethylene such as PVC.
