92 parts by mass of water, 1 part by mass of coupling agent, 1 part by mass of water repellent, 1 part by mass of dustproof oil and 5 parts by mass of bio-based resin are stirred for 20 minutes to obtain the rock wool binder of the embodiment.
The rock wool of the embodiment is mainly prepared from the following components in parts by mass:
50 parts by mass of basalt
20 parts by mass of dolomite
10 parts by mass of slag
10 parts by mass of coke
And 20 parts by mass of bio-based resin.
The preparation method of the rock wool provided by the embodiment comprises the following steps:
(1) melting 50 parts by mass of basalt, 10 parts by mass of dolomite, 20 parts by mass of slag and 10 parts by mass of coke into fluid at the temperature of about 1300 ℃; (in this example, the raw materials may be transported to a cupola or an electric furnace by a conveyor belt and melted)
(2) Then, 20 parts by mass of the binder and the fluid in the step (1) are input into a four-roller centrifuge and sprayed into fibers;
(3) the fibers prepared in the step (2) sequentially pass through a collector and a curing furnace, and are finally cured and molded, wherein the temperature of an air inlet in the curing furnace is 230 ℃, and the temperature of an air outlet in the curing furnace is 180 ℃;
(4) and cutting and packaging after curing.
The rock wool board hardness of this embodiment is softer, and the layering is severe, can not satisfy construction application demand. As shown in fig. 3.
Adopts Wanhua acrylic acid AA and a novel bio-based product 'bio-propylene glycol' which is prepared from starch corn by DuPont company. The resin for rock wool according to the invention cannot be produced.
In conclusion, the formaldehyde-free rock wool binder prepared by mixing the acrylic-based resin and the bio-based resin not only solves the problem that rock wool products contain formaldehyde, but also solves the problems that rock wool produced by using the acrylic-based resin is difficult to cure and the water absorption rate of rock wool products produced by using the bio-based resin is high.
