Problems solved by technology

First of all, the fire-resistant expansion (seal) strip is soft in texture and needs to be used in combination with steel lining and cutting strips, which will increase the cost; in addition, the use of pouring materials will cause the door and window frames of fire-resistant doors and windows to accumulate moisture for a long time, which will cause corrosion to the door and window frames ;Thirdly, the fire-proof inserts need to be close to the size of the door and window frame cavity, and then the mass production of fire-proof inserts cannot be realized for different sizes of door and window frames
In summary, the existing refractory materials increase the production and maintenance costs of refractory doors and windows to a certain extent

Embodiment 1

[0039] In view of this, if figure 1 As shown, the present invention provides a method for making inflatable fireproof inserts, comprising the following steps:

[0040] S01: Mix the raw materials of the intumescent fireproof cuttings according to the preset weight ratio to obtain the mixture;

[0041] The above-mentioned mixture forms the base material of the above-mentioned intumescent fireproof inserts through processes such as stirring, extruding, and cutting. It should be noted here that, according to the composition difference of the mixture, the above-mentioned base material can be set as intumescent type or non-intumescent type according to needs.

[0042] S02: adding brine into the mixture and stirring to obtain a paste;

[0043] Among them, brine is a mixture of magnesium chloride, magnesium sulfate and sodium chloride, which is usually used for protein coagulation. The above-mentioned brine is added to the above-mentioned mixture, followed by stirring to solidify. ...

Embodiment 2

[0053] On the basis of Example 1, in a preferred implementation manner, the above-mentioned intumescent fireproof inserts are made into a structure in which the base material intumescent trim does not inflate. Specifically, the intumescent fireproof cuttings consist of 101 parts of expansive material, 100 parts of magnesium oxide, 1 part of additive, 100 parts of sawdust, 50 parts of water, 0.2 part of fiber net and 15 parts of decorative cloth.

[0054] Wherein the above-mentioned expanded material includes vermiculite and / or expanded graphite, and the mass ratio of vermiculite to expanded graphite is 100:1. The above-mentioned decorative cloth adopts non-woven fabric. The preparation process of the above-mentioned intumescent fireproof cuttings is as in Example 1, and will not be repeated here.

Embodiment 3

[0056] On the basis of Example 1, in a preferred implementation manner, the above-mentioned intumescent fireproof insert is made into a structure in which the base material does not inflate the decorative cloth. Specifically, the intumescent fireproof cuttings consist of 100 parts of magnesium oxide, 1 part of additive, 100 parts of sawdust, 50 parts of water, 0.2 part of fiber net and 20 parts of decorative cloth.

[0057] Compared with the lack of expansion material in the above-mentioned base material in the second embodiment, the decoration cloth is preferably made of a material with a high expansion rate (high temperature expansion cloth). The above-mentioned high expansion ratio has a relatively high coefficient of thermal expansion, including but not limited to the use of polyethylene and the like. The preparation process of the above-mentioned intumescent fireproof cuttings is as in Example 1, and will not be repeated here.

Abstract

The invention provides an expansion type fireproof insertion strip, a manufacturing method thereof and a fireproof door and window. The manufacturing method comprises the following steps that raw materials of the expansion type fireproof insertion strip are mixed according to a preset weight ratio to obtain a mixture; brine is added into the mixture, and then is stirred to obtain paste; a fiber net and decorative cloth are added to the top and / or the bottom of the paste, and then are extruded to form a plate-shaped object; and the plate-shaped object is aired and cut to obtain the expansion type fireproof insertion strip. According to the expansion type fireproof insertion strip, the manufacturing method thereof and the fireproof door and window, the raw materials and the brine are mixed and stirred according to the preset proportion, the fiber net and the decorative cloth are added to provide structural strength, cutting and fixing are conducted according to the sizes of different cavities of the fireproof door and window, the expansion effect is generated in a fire disaster, the defect that mass production cannot be carried out according to different sizes of door and window frames is overcome, smoke and water vapor generated in the flame retardant process of the expansion type fireproof insertion strip are little, corrosion to the door and window frames is little, and the production and maintenance cost of the expansion type fireproof insertion strip is reduced.

Description

technical field [0001] The invention relates to the technical field of fire-resistant doors and windows, in particular to an intumescent fireproof insert, a manufacturing method thereof, and fire-resistant doors and windows. Background technique [0002] Fire-resistant doors and windows are a kind of fire-resistant doors and windows that can meet the performance requirements of building exterior windows, meet the testing requirements of non-insulated fire-proof windows of Class C of other materials, and have a fire-resistant integrity of not less than one hour. Usually fire-resistant door and window frames are filled with refractory materials to prevent heat conduction, flame retardancy and provide structural strength. The refractory materials used in the existing fire-resistant door and window frames mainly include fire-resistant expansion sealing strips, steel linings, pouring materials, and fire-resistant cutting strips. [0003] However, the above-mentioned refractory m...
