Description
Technical Field
The utility model relates to a polyurethane foam board.
Background
The rigid polyurethane foam is a high molecular polymer prepared by mixing isocyanate and polyether serving as main raw materials through special equipment under the action of various auxiliary agents such as a foaming agent, a catalyst, a flame retardant and the like and performing high-pressure spraying and on-site foaming. Polyurethane has both soft and hard foams. The soft bubbles are in an open pore structure, and the hard bubbles are in a closed pore structure; soft foams are classified into skinned and non-skinned.
The primary function of the polyurethane soft foam is cushioning. Polyurethane flexible foams are commonly used in sofa furniture, pillows, cushions, toys, apparel and sound insulation liners.
The polyurethane rigid foam is a novel synthetic material with heat preservation and waterproof functions, has low thermal conductivity coefficient, is only 0.022-0.033W/(m x k), is equivalent to half of an extruded sheet, and is the lowest thermal conductivity coefficient in all the heat preservation materials at present. The hard polyurethane foam plastic is mainly applied to heat preservation of building outer walls, integration of roof waterproof and heat preservation, heat preservation and heat insulation of refrigerators, pipeline heat preservation materials, building boards, refrigerated trucks, cold storage heat insulation materials and the like.
Because the properties of the hard polyurethane foam and the soft polyurethane foam are different, the polyurethane foam is often independently suitable for different products. Nowadays, the functional requirements of polyurethane products are higher and higher, so that if the rigid polyurethane foam and the flexible polyurethane foam can be combined together, all the functions of the two polyurethane foams can be obtained. The most existing method adopts glue for compounding, but has the defects that the glue consumption is large, a large amount of glue influences the function of polyurethane foam, and meanwhile, a large amount of toxic substances which are difficult to decompose and easy to volatilize exist in the glue.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a polyurethane foam board aims at solving above-mentioned problem.
In order to achieve the purpose, the technical scheme of the utility model is to design a polyurethane foam board, which comprises a polyurethane hard foam body outer layer and a polyurethane soft foam body inner layer; the outer layer of the rigid polyurethane foam body is provided with two pieces, the section of the outer layer of the rigid polyurethane foam body is in an L shape, a slot is arranged in the direction of the vertical end of the rigid polyurethane foam body towards the horizontal end, and a plurality of strips are arranged on the surface of one side of the horizontal end of the rigid polyurethane foam body towards the vertical end; the end part of the horizontal end of the outer layer of the polyurethane hard foam body is provided with an inserting block; the plug block can be embedded into the slot; two sides of the outer layer horizontal end of the rigid polyurethane foam body are provided with baffles; the upper surface and the lower surface of the inner layer of the polyurethane soft foam body are provided with a plurality of strip grooves; two hard bubble body outer mirror images of polyurethane set up, and the soft bubble body inlayer of polyurethane is put into two hard bubble body skin middles, and two hard bubble body outer rectangular pieces of polyurethane imbed the rectangular inslot of the soft bubble body inlayer of polyurethane respectively, and two hard bubble body outer inserted blocks of polyurethane are pegged graft with the slot each other, with the soft bubble body inlayer parcel of polyurethane in two hard bubble body skin.
And glue is uniformly coated on the parts (including the contact surfaces of the insert block and the slot and the contact surfaces of the baffle plate and the baffle plate) connected with the outer layers of the two rigid polyurethane foams.
The utility model has the advantages and the beneficial effects that: the utility model discloses a polyurethane foam board can realize the purpose together with the hard bubble body of polyurethane and the soft bubble body complex of polyurethane, and simultaneously furthest's reduction or do not use glue. The utility model discloses a polyurethane foam plate simple structure, and the environmental protection.
