Abstract
The invention provides a HDPE flame-retardant pipe for building drainage, which is prepared from the following components in parts by weight: 100 parts of high-density polyethylene resin; 8-13.5 parts of a flame retardant; 0.5-1.5 parts of a stabilizer; 0.5-1.0 part of a lubricant; 2.5 to 3.0 parts of filler. The HDPE flame-retardant pipe for building drainage meets the mechanical property for building drainage and has good flame-retardant effect.
Description
Technical Field
The invention relates to the technical field of pipes, in particular to a HDPE flame-retardant pipe for building drainage.
Background
Along with the continuous improvement of living standard of people, the requirement on the use materials in the building is higher and higher, and the requirement of safe people on fire prevention of the drainage pipe in the building is higher and higher. At present, the PE drainage pipe material for building drainage is produced from single polyethylene resin, does not have a flame retardant function, is not an ideal material in the aspect of use safety, and has certain potential safety hazard.
Disclosure of Invention
The present invention has been made to solve the above problems, and an object of the present invention is to provide a HDPE flame retardant pipe for building drainage, which can enhance the flame retardant property of the pipe and increase the safety in use.
In order to achieve the purpose, the invention adopts the following technical scheme:
the invention provides a HDPE flame-retardant pipe for building drainage, which is characterized in that: the pipe is prepared from the following components in parts by mass:
further, the HDPE flame-retardant pipe for building drainage provided by the invention can also have the following characteristics: the flame retardant comprises decabromodiphenyl ether, red phosphorus flame retardant, antimony trioxide and aluminum hydroxide.
Further, the HDPE flame-retardant pipe for building drainage provided by the invention can also have the following characteristics: the flame retardant comprises the following components in parts by mass:
further, the HDPE flame retardant pipe for building drainage provided by the invention can also have the following characteristics: wherein the stabilizer is one or more of calcium salt, zinc salt, magnesium salt and compound containing alkanoyl.
Further, the HDPE flame-retardant pipe for building drainage provided by the invention can also have the following characteristics: wherein the lubricant is any one or more of fatty acid, fatty acid ester, and solid higher aliphatic hydrocarbon.
Further, the HDPE flame-retardant pipe for building drainage provided by the invention can also have the following characteristics: wherein the filler is carbon black.
The invention has the beneficial effects that:
the HDPE flame-retardant pipe for building drainage has a good flame-retardant effect by adding the flame retardant, the stabilizer, the lubricant and the carbon black in specific components and proportions. Compared with the common HDPE pipe without the flame retardant, the flame retardant effect of the HDPE flame retardant pipe is improved qualitatively, furthermore, the flame retardant in the HDPE flame retardant pipe is combined by decabromodiphenyl ether, a red phosphorus flame retardant, antimony trioxide and aluminum hydroxide in a specific ratio, and the synergistic effect of the decabromodiphenyl ether, the red phosphorus flame retardant, the antimony trioxide and the aluminum hydroxide enables the flame retardant effect of the pipe to be obvious compared with the pipe only added with one or two flame retardants.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the technical scheme of the invention is specifically described in the following embodiments.
< example 1>
The raw materials are weighed according to the following formula, blended and granulated, and extruded and molded by a single-screw extruder to obtain the pipe.
The formula is measured according to the parts by mass:
< comparative example 1>
The raw materials are weighed according to the following formula, blended and granulated, and extruded and molded by a single-screw extruder to obtain the pipe.
The formula is measured according to the mass parts:
< comparative example 2>
The raw materials are weighed according to the following formula, blended and granulated, and extruded and molded by a single-screw extruder to obtain the pipe.
The formula is measured according to the mass parts:
< comparative example 3>
The raw materials are weighed according to the following formula, blended and granulated, and extruded and molded by a single-screw extruder to obtain the pipe.
The formula is measured according to the mass parts:
< comparative example 4>
The raw materials are weighed according to the following formula, blended and granulated, and extruded and molded by a single-screw extruder to obtain the pipe.
The formula is measured according to the parts by mass:
and (3) testing mechanical properties:
each of the sections of the pipes of example 1 and comparative examples 1 to 4 was taken as a test sample, and the elongation at break and strength of each sample were tested. All the samples tested in example 1 and comparative examples 1 to 4 meet the technical requirements of PE pipes for building drainage, and can replace the existing PE pipes in terms of mechanical strength.
And (3) testing the flame retardant property:
the pipe materials of example 1 and comparative examples 1 to 4 are taken, and 6 test pieces with the same specification are taken in each example or comparative example, wherein the test pieces are arc-shaped test pieces with the width of 25 mm.
The fuel is a mixture of 95% industrial ethanol and 5% methanol; the flame length of the alcohol blast burner is 150 mm-180 mm, and the flame temperature is (960 +/-60) DEG C.
The testing steps are as follows:
the alcohol blast burner is vertically arranged in a test box, fuel is injected into the preheating plate, then the preheating plate at the periphery of the alcohol blast burner is ignited, when the total fuel consumption in the preheating plate is 50%, a control valve of the alcohol blast burner is opened, after flame is stably combusted for 5min, when the measurement temperature reaches the range of (960 +/-60) DEG C, a test piece is arranged on the flame of the alcohol blast burner, the alcohol blast burner is moved away after the test piece is combusted, and the number of flame combustion time which is not more than 3s and the number of flame combustion time which is not more than 10s in 6 test pieces are calculated.
The flame retardant test results are shown in the following table:
as can be seen from the experimental data in the above table, the pipe of comparative example 4 does not contain a flame retardant component, and it does not have a flame retardant effect, whereas example 1 and comparative examples 1 to 3, to which a flame retardant component is added, both have a flame retardant effect; the pipe of the comparative example 1 is only added with decabromodiphenyl ether and antimony trioxide as flame retardants, and the flame retardant effect is not as good as that of the pipe with four flame retardant components; the tube of comparative example 2, in which only the red phosphorus flame retardant was added, had a less flame retardant effect than the tube of the present invention having four flame retardant components; the pipe of comparative example 3, in which only aluminum hydroxide was added as a flame retardant, was inferior in flame retarding effect to the pipe of the present invention having four flame retardant components. Therefore, the formula of the pipe is better, and the flame retardant effect is optimal.
The above embodiments are only specific embodiments of the present invention, and are not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
