It is an advantage of the invention that: the method for comprehensive utilization that glass fiber waste silk of the present invention makes fire-retardant heat-insulation material adopts new production technique, carry out waste silk short cutting, shredding, the mode such as combing again process, then produce the matrix material of all kinds of high added values such as insulation quilt, noise elimination felt, fire retardant felt pipe after deep processing. It is simple that the present invention reduces production cost, making method; The present invention can eliminate waste silk to the pollution of environment while producing, and thoroughly solves a difficult problem for this puzzlement matrix material, have good economic benefit and social benefit from source.
Embodiment
With specific embodiment, the invention will be further described below:
A kind of glass fiber waste silk makes the method for comprehensive utilization of fire-retardant heat-insulation material, comprising the following steps: a, be main raw material taking glass fiber waste silk, glass fiber waste silk is carried out short cutting, the short length cut is 20-40mm, when short to cut length be 20mm or 25mm time, be best result of use; B, the glass fiber waste silk after short cutting is carried out shredding, when short to cut length be 25mm time, the glass fibre scatter coefficient after shredding is best, and wetting property is good; C, the glass fiber waste silk after shredding is carried out combing; Obtain fire-retardant heat-insulation material.
In the present embodiment, the glass fiber waste silk after combing is added Feldspar Powder, calcium oxide mixing, makes admixtion; Feldspar Powder is 10-12 part be weight, and calcium oxide is 7-10 part be weight.
In the present embodiment, by described admixtion melting, then melting material is imported whizzer and obtain this product.
In the present embodiment, Feldspar Powder weight is preferably 10 deals.
In the present embodiment, calcium oxide weight is preferably 9 deals.
The invention has the beneficial effects as follows: glass fibre is reprocessed by the present invention, focus on waste glass fibre, not only prevent glass fiber waste silk to run off and cause environmental pollution, and it is low to have production cost, the advantages such as construction cost is few, it it is the technological transformation project of comprehensive utilization of resources, meet national industrial policies and environmental regulation, after this production line is gone into operation, not only production cost much slower, produce insulation, noise reduction, fire-proof felt, glass is cotton, the matrix material of all kinds of high added values such as glass insulation thimble, and belong to first production line adopting waste silk completely in China, for China's glass-fiber industry waste silk " turning waste into wealth " provides new thinking, there is higher promotional value, therefore this project has good Social benefit and economic benefit.
