Abstract
The utility model relates to a wheat straw light heat-insulating thick plate with a surface covered by a polyurethane foaming material, which is composed of an inner lining 2 and an outer layer 1. The inner liner 2 is made of a wheat straw heat-insulating material, the outer layer is made of a polyurethane foaming material, and the inner liner 2 is of a rectangular thick plate shape. The utility model has similar performance with a polyurethane foaming material with the same density, but the cost is reduced greatly, the range of application is widened, and the utility model is an ideal heat-insulating material.
Description
The utility model relates to a kind of wheat straw light thermal-insulation slab, belong to non-wooden compound insulating material technical field with the polyurethane foam material coverlay.
Insulation material of the prior art has and single makes of polyurethane foam material, shape each one, and be individual layer.Though its purposes enlarges day by day, because cost is higher, make its use be subjected to certain placing restrictions in some occasion,
The purpose of this utility model is the problem at above-mentioned existence, proposes the new insulation material that a kind of cost is low, purposes is wide---with the wheat straw light thermal-insulation slab of polyurethane coverlay.
Technical solution of the present utility model:
It is made up of liner 2 and outer 1, and liner 2 is to make with the wheat straw insulation material, and skin is to make with polyurethane foam material, liner 2 rectangular thick plate-like.
Advantage of the present utility model:
1, be base material with lightweight wheat straw insulation material, outer surface polyurethane foam material coverlay, its performance is similar to the polyurethane foam material of same density, but cost can descend significantly.
2, thermal and insulating performance is good.
3, applied widely.
Accompanying drawing is a structural representation of the present utility model.
Further describe technical solution of the present utility model below in conjunction with accompanying drawing:
Remove rotten, the rotten part in the wheat straw, be processed into shaft-like unit about long 50MM with chaffcutter then, in special-purpose glue mixer, wheat straw is carried out applying glue and stirring, mat formation into the slab of certain specification size after evenly, after hot pressing, saw limit, finished product.One special framed in, add earlier a certain amount of two component polyurethane expanded material, put into above-mentioned finished product then, pour remaining polyurethane foam material again into, and will seal by predetermined size, make the density that reaches regulation behind the polyurethane foam, just become double thickness sheet material material after the demoulding.It is made up of liner 2 and outer 1, and liner 2 is to be made by the wheat straw insulation material, and outer 1 is to be made by polyurethane foam material, the rectangular thick plate-like of the shape of liner 2.
Claims (1)
1,, it is characterized in that it forms the rectangular thick plate-like of liner (2) by liner made from the wheat straw light heat insulation material (2) and the skin (1) made with polyurethane foam material with the wheat straw light thermal-insulation slab of polyurethane coverlay.
