Abstract

The utility model relates to a vermiculite fire-proof thermal-insulating yarn, comprising a plurality of fibres of the asbestos. The vermiculite fire-proof thermal-insulating yarn is characterized in that the vermiculite and the bond are contained in the yarn, the vermiculite is in the scaled shape, and the asbestos is mingled together with the vermiculite and the bond. The weight ratio of the asbestos and the vermiculite is 1; 1. 5-2. The weight ratio of the bond and the total weight is 1-2; 100 The vermiculite fire-proof thermal-insulating yarn has the advantages that the fire resistance is high, the effect of the thermal insulation is good, the flexible fireproof material which is made of the vermiculite fire-proof thermal-insulating yarn is conveniently to coil, fold, and cut, and the application field of the vermiculite fire-proof thermal-insulating yarn is wide.

Description

Vermiculite fire-proof and thermal-insulation yarn

Technical field

The utility model belongs to the fire-proof and thermal-insulation insulation material, is a kind of vermiculite fire-proof and thermal-insulation yarn specifically, can be used for stopping, isolating of flame region, heat conduction, thermal-radiatingly stops and isolates.

Background technology

Vermiculite is a kind of moisture aluminium mineral material, and external form is flakey, and that general color has is golden yellow, two kinds of silvery whites.Nontoxic, tasteless, radiationless, heat resisting temperature is generally at 1000～1100 ℃, and acoustic absorptivity 0.06～0.6 burns vector less than 10%, 1350～1600 ℃ of fusing points.Have fire prevention, heat insulation, sound insulation, antidetonation, without putrefaction, good characteristic such as never degenerate.But because the natural appearance structure of vermiculite, can not use in a large amount of fire prevention, occasion such as heat insulation.Existing vermiculite is in fire prevention, application technology aspect heat insulation, generally be to adopt the method for filling, in needs fire prevention or heat insulation occasion, adopt other material earlier, as: iron plate, aluminium sheet etc. makes an interlayer body, then vermiculite is packed in the interlayer, allow it play fire prevention, heat-blocking action, but the limitation of this method is very big, expense is higher, it is also big to take a lot of work, and has limited application.Another method is: puddle fortifying fibre and adhesive in vermiculite, then, be pressed into the vermiculite board material under the state of uniform temperature.Need on request shape to tailor during use, also there is very big limitation in this method, as batch at needs, fold, this vermiculite sheet material just can not be used under the mobile situation.Therefore, in existing two class methods that vermiculite is used, both took a lot of work, expense is high again, and is difficult to use in a lot of occasions.In the prior art, the production of wet method asbestos yarn is that asbestos fibre is passed through to add bleeding agent, soaks, and stirring pulping then, draws serous coat, allows serous coat solidify in color-fixing agent again, again the film after solidifying is twisted into line.Do not have vermiculite in its yarn texture, asbestos fibre is only arranged, fire protecting performance is not too high, and effect of heat insulation is also not so good.

Summary of the invention

The purpose of this utility model is the deficiency that exists at prior art, and a kind of vermiculite fire-proof and thermal-insulation yarn is provided, the fire protecting performance height, and good heat-insulation effect is convenient to batch, folds, is cut out by its fire resistant flexible material of making, and Application Areas is extensive.

The purpose of this utility model is achieved by the following technical solution: a kind of vermiculite fire-proof and thermal-insulation yarn, comprise asbestos fibre, and it is characterized in that also comprising vermiculite and adhesive in the yarn, vermiculite is flakey, and asbestos fibre is mixed in therebetween.

Described asbestos fibre and vermiculite weight ratio are 1: 1.5～2,1%～2% of binder constitutes gross weight.

The utility model compared with prior art has the following advantages and good effect:

1, the utility model adds the vermiculite yarn that part asbestos fibre and adhesive are made with the vermiculite for the main body composition, do not change the vermiculite characteristic, by slurrying, film forming, the method for solidifying, twisting, make vermiculite can form yarn, and brute force is bigger, and can be woven into vermiculite cloth, band, be compiled into the vermiculite rope, these cloth, band, rope can be cut into difformity according to different needs again, it is folding to curl, and the filled chamber of design separately that also do not need to pack into can directly use, easy to use, Application Areas is very wide.Overcome vermiculite because of sclay texture should not be made flexible fire, heat-barrier material causes the narrow shortcoming of application surface, for this novel fire prevention of vermiculite, heat-barrier material have been expanded bigger application space.

2, simplify production technology, reduced manufacturing cost, easy to use.

3, the heat-insulating, fire-preventing product thermal conductivity factor of the utility model yarn making is minimum, and heatproof Du Keda is used for heat insulation occasion more than 900 ℃, can cut down the consumption of energy greatly, be used under the fireproof occasions, can effectively stop spreading of flame, have good economic benefit and social benefit.

Description of drawings

Fig. 1 is the local amplification assumption diagram of the utility model vermiculite fire-proof and thermal-insulation yarn.

The specific embodiment

Referring to Fig. 1, comprise vermiculite 1, asbestos fibre 2 and adhesive in the vermiculite fire-proof and thermal-insulation yarn of the present utility model, vermiculite 1 is flakey, and asbestos fibre 2 is mixed in therebetween, bonds mutually by adhesive.Asbestos fibre 2 is 1: 1.5～2 with the weight ratio of vermiculite 1,1%～2% of binder constitutes gross weight.

Because of having added part asbestos fibre 2, improved the undercapacity that vermiculite 1 produces because of the shape reason greatly, because about 700 ℃ of asbestos fibre 2 heatproof Du Keda own, when with after vermiculite 1 combines, made vermiculite yarn heatproof Du Keda is more than 900 ℃, and the short time can be born 1100 ℃ of high temperature.Because this yarn is softer, thermal conductivity factor is extremely low, and its shape can change arbitrarily, therefore, cloth, band, the rope that can be processed into all size with vermiculite fire-proof and thermal-insulation yarn of the present utility model are used for heat insulation, fireproof occasions, can effectively stop spreading of flame, and have good effect of heat insulation.

And the preparation method of the utility model vermiculite fire-proof and thermal-insulation yarn product is: the production method of pressing the wet method asbestos yarn earlier, asbestos fibre 2 is passed through to add bleeding agent, soak, then, be the production characteristics of the utility model vermiculite fire-proof and thermal-insulation yarn product, promptly when asbestos stir pulping, the vermiculite that adds asbestos weight 150%～200% again, and the adhesive of adding gross weight 1%～2%, participate in stirring pulping jointly, afterwards, draw serous coat by existing production routine again, serous coat is solidified in coagulating agent, again the film after solidifying is twisted into line.So just having produced a kind of is the vermiculite yarn of main body composition with the vermiculite.The performance of this yarn has mainly showed the performance of vermiculite, and the adding of its asbestos fibre has replenished intensity for lepidiod vermiculite, and does not change the chemical property and the apparent condition of vermiculite 1.So just can give full play to the intrinsic property of vermiculite 1, expand the application of vermiculite 1 in fire prevention, heat insulation field.

Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present utility model, the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
