Description
Technical Field
The invention belongs to the field of engineering plastic application, and particularly relates to application of engineering plastic adopting brominated phenolic substances in insect prevention.
Background
In recent years, with the improvement of living standard of people, smart home products are gradually popularized, and various sensors form important components of the smart home products, such as a smoke alarm, a gas alarm, a rain sensor, a human body sensor and the like. These sensors are all charged parts, and can generate heat to a certain extent during use, and attract various insects and organisms to approach. If a large number of organisms such as insects around the sensor gather, the sensor can be out of order, and the intelligent home system cannot operate normally. If the alarm type inductor is out of order, the potential safety hazard is very large, for example, a smoke detector and a smoke detection device shell are required to be provided with a plurality of holes connected with the environment, and smoke can enter the device. If the small mosquitoes or small flying insects are attracted by the visible light or infrared light emitted by the detector and gather towards the detector, the small mosquitoes or small flying insects can block the hole of the shell and even enter the detection labyrinth, and the sensor is misreported or fails. Therefore, it is very important that the sensor plastic has insect prevention effect.
Chinese patent CN107722505A discloses a tough flaky insect-repellent plastic master batch for lamination molding and a preparation method thereof, wherein the master batch comprises 100 parts by weight of carrier resin, 3-15 parts by weight of insect repellent, 20-50 parts by weight of bast fiber, 3-5 parts by weight of curing agent, 10-25 parts by weight of inorganic filler and 30-80 parts by weight of organic solvent, based on 100 parts by weight of carrier resin. The plastic master batch fuses the insect repellent into carrier resin, and the insect repellent can be directly added into laminated home for use, so that the laminated board has a long-lasting and long-acting insect repellent effect. However, the insect-repellent effect of the plastic masterbatch is still to be improved.

The composite materials of examples 1 to 17 and comparative examples 1 to 6 were dried and injection molded into a wafer having a thickness of 3.0mm for testing insect-proofing performance. The composites of examples 8-17 and comparative examples 4-6 were injection molded into tensile, bending and notched impact bars of the ISO standard for mechanical testing. The insect control test is as follows:
the test device comprises: two transparent organic glass square boxes with the size of 50cm multiplied by 50cm are respectively marked as A, B, air holes are reserved at the tops of the square boxes, the air holes are covered by anti-mosquito cloth during testing, and insect placing holes are arranged at the left lower corners of the square boxes. The square boxes are connected by a transparent organic glass pipeline with the diameter of 20 multiplied by 100cm, and two ends of the connecting pipeline are provided with movable clapboards.
Testing insects: female mosquitoes which do not suck blood after the culex pipiens pallens eclosion;
the test conditions are as follows: the temperature is 26 +/-1 ℃, and the humidity is 65% +/-10%;
the test method comprises the following steps: the discs in the examples are subpackaged in cylindrical packaging bottles, the bottle caps are opened, and the samples are sealed for standby after natural volatilization for 0 day, 7 days, 14 days, 21 days and 28 days under indoor conditions. 50 test insects are sucked by a mosquito sucking pipe, the A square box is placed into the insect placing hole, the insect placing hole is closed, the channel movable partition plate is in a closed state, 1 bottle of sample to be tested is taken after the test insects normally move, the center of the A square box is placed after the sample is unsealed, the movable partition plate of the channel is opened, timing is started, the channel movable partition plate is closed after 30 minutes, the number of escaping mosquitoes and the number of knocking down mosquitoes are recorded, the test is repeated for three times, and the average value of the test results is obtained. After each test, the entire experimental setup was cleaned and the next experiment was performed. The repelling rate is (number of escaping mosquitoes plus number of knockdown mosquitoes)/50 multiplied by 100%.
The test results of the composites of examples 1 to 7 and comparative examples 1 to 3 are shown in Table 1, and the test results of the composites of examples 8 to 17 and comparative examples 4 to 6 are shown in Table 2.
TABLE 1
As can be seen from table 1, the composite material in comparative example 1 or comparative example 2 has no insect repellent added thereto, and the repellent rate to mosquitoes is only about 20%, whereas the composite material in example 1 or example 2 has the insect repellent added thereto, and the repellent rate to mosquitoes of the sample after being placed for 28 days reaches more than 94%, and the effect of the placement time on the repellent rate is not great. Although the composite materials of comparative examples 1-2 did not contain an insect repellent, some insects entered the box B through the passage due to the problem of the test method itself, so that the repellency rate was not 0. In addition, the insect-resistant agents are added into the composite materials in the examples 3-7, the repellent rate of the sample on mosquitoes reaches over 96% after the sample is placed for 28 days, and the effect of the placement time on the repellent rate is small. The composite material in the comparative example 3 is added with the conventional insect-proofing agent, so that the repellent rate of the composite material to mosquitoes is not high, and the insect-proofing effect is obviously inferior to that in the example 3. Therefore, brominated phenolic substances are added into the ABS composite material, so that the composite material has a good insect prevention effect.
TABLE 2
As can be seen from table 2, the composite material in comparative example 4 has no insect repellent, and the repelling rate of the sample on mosquitoes after being placed for 28 days is not high, and the composite material in example 9 has brominated phenolic substances, so that the repelling rate of the sample on mosquitoes after being placed for 28 days is high, and the influence of the placing time on the repelling rate is not great. Although the composite material of comparative example 4 did not contain an insect repellent, a part of the insects entered the box B through the passage due to the problem of the test method itself, so that the repellency rate was not 0. The composite material in the comparative example 6 is added with the conventional insect-resist agent, so that the repellent rate of the composite material on mosquitoes is not high, and the insect-resist effect is not good as that of the composite material in the example 9. In addition, the brominated phenolic substances are added into the composite materials in the embodiments 8 and 10 to 17, the repellent rate of the sample on mosquitoes after being placed for 28 days can basically reach more than 80%, and the influence of the placing time on the repellent rate is small. Therefore, the brominated phenolic substances are added into the HIPS resin, so that the HIPS material has a good insect prevention effect. In addition, the composite material in the comparative example 5 has lower notched impact strength without adding a compatibilizer, while the composite material in the example 9 has higher notched impact strength with adding a compatibilizer, that is, the addition of the compatibilizer can greatly improve the notched impact strength of the composite material.
