Abstract
The invention discloses a polyurethane heated composition board and a production method thereof, wherein, a heated board comprises a high-density high hard integral skin urethane foam plate on which a low-density urethane foam plate is compounded. The production method is as follows: the high-density high hard integral skin urethane foam plate is produced first, then the low-density urethane foam plate is compounded on the high-density high hard integral skin urethane foam plate through a cementing compound or direct foaming. The composition board is light in weight, safe and reliable, simple in process, can realize industrialized production and construction assembly manner.
Description
Technical field:
The present invention relates to a kind of constructional materials, is polyurethane thermal insulation board and production technology.
Background technology:
The method site operation that polyurethane heat-insulation technology in the past adopts spraying usually utilizes the polyurethane high adhesive property, is bonded in the surface of wall of insulation, to reach the effect of energy-saving heat preserving.Polyurethane is the good binding material of a kind of adhesive property, can carry out good bonding with a lot of object surfaces.But the resulting insulation layer of the method for such site operation is because not protection of surface suffers hard thing collision back cracky, thereby lost heat preservation effect.And site operation is difficult to guarantee construction quality for vertical wall construction difficulty.Simultaneously, site operation gained insulation layer surface is not attractive in appearance.
Another is the polyurethane heat-insulation decorative board material that batch production is produced, in order to adapt to the needs in market, reach attractive and durable requirement, this class polyurethane heat-insulation decorative board material usually will be at its surface adhesion or applying ceramic tile or cement board when producing, perhaps aluminium alloys etc.But this technique for manufacturing decorative boards or post-processed complex process.For example a kind of decorative panel is chosen in its external surface decoration ceramic tile, and its complex manufacturing is wanted present polyurethane sheet surface applied polymer mortar, and then added alkali-resistant glass fibre cloth, and then adds the one layer of polymeric mortar, and last surface could the applying ceramic tile.But the applying of ceramic tile and polyurethane realizes by adhesive like this, because the about 10mm of the thickness of ceramic tile itself, its weight is heavier, 1 square metre about about 20 kilograms, therefore causes easily to come off.In the future safety is impacted.
Summary of the invention:
The object of the present invention is to provide a kind of in light weight, safe and reliable, technology is simple, can realize suitability for industrialized production, construction assemblingization polyurethane heat-preserving composition board and production method.
Technical solution of the present invention is:
A kind of polyurethane heat-preserving composition board is characterized in that: comprise high density high rigidity polyurethane integral skin foam plastic plate, be compounded with the low density polyurethane foam plate on the high density high rigidity polyurethane integral skin foam plastic plate.
The hardness of high density high rigidity polyurethane integral skin foam plastic plate is more than the Shao Shi 60D, preferably more than the 70D.
Contain the strength-enhanced filler in the high density high rigidity polyurethane integral skin foam plastic plate.
The strength-enhanced filler is glass fiber or nano-calcium carbonate, and its consumption is 4～8% of a high density high rigidity polyurethane integral skin foam plastic plate raw material gross weight.
High density high rigidity polyurethane integral skin foam plastic plate is connected by polyurethane adhesive with the low density polyurethane foam plate.
High density high rigidity polyurethane integral skin foam plastic plate is connected by the foaming connected mode with the low density polyurethane foam plate.
A kind of production method of polyurethane heat-preserving composition board is characterized in that: comprise the following steps:
(1) raw material with production high density high rigidity polyurethane integral skin foam plastics configures, and close die is used the casting machine pouring foaming, obtains high density high rigidity polyurethane integral skin foam plastic plate;
(2) simultaneously be coated with polyurethane adhesive the non-of high density high rigidity polyurethane integral skin foam plastic plate from skinning, on then the low density polyurethane foam plate being fitted, treat adhesive solidification after, promptly obtain polyurethane heat-preserving composition board.
A kind of production method of polyurethane heat-preserving composition board is characterized in that: comprise the following steps:
(1) raw material with production high density high rigidity polyurethane integral skin foam plastics configures, and close die is used the casting machine pouring foaming, obtains high density high rigidity polyurethane integral skin foam plastic plate;
(2) with high density high rigidity polyurethane integral skin foam plastic plate as base plate, non-ly simultaneously carry out the foaming of low-density polyurethane sheet material at it from skinning, obtain polyurethane heat-preserving composition board.
When making high density high rigidity polyurethane integral skin foam plastic plate, also add the glass fiber or the nano-calcium carbonate of high density high rigidity polyurethane integral skin foam plastic plate raw material gross weight 4～8%.
The present invention compares with existing technology has following effect: the present invention combines low-density polyurethane rigid foam plate and high-density hard polyurethane integral skin foam plastics and has obtained polyurethane combined decoration plate.Adopt low-density polyurethane rigid foam plate to give this plate good heat preservation energy-saving function.Because be all polyurethane material, so the bonding force between two plates is strong, the danger that does not come off.Is finish coat with high density from skinning hard polyaminoester plastics, have the intensity height, in light weight, impact resistance good, and effect such as supporting capacity, anti-pressure and abrasion-proof is preferably arranged.Simultaneously can make various patterns or decorative pattern, have the excellent decoration effect, can be used for the decoration of vertical body of wall from skinning surfaces, easy for installation.
The invention will be further described below in conjunction with drawings and Examples.
