Description

Technical Field

[0001] This invention relates to the field of engineering materials technology, and in particular to an AS-coated glass fiber alloy material. Background Technology

[0002] Currently, affected by fluctuations in the domestic and international chemical industries and increasingly stringent environmental policies, the production costs of various injection molded parts have risen sharply. At the same time, the downstream home appliance industry faces a less than optimistic outlook, with overcapacity becoming increasingly prominent. Under these circumstances, reducing production costs has become a crucial issue that the home appliance industry urgently needs to address.

[0003] In the field of plastics materials, traditional injection molding materials have many shortcomings. For example, ordinary modification techniques are often limited to PVC resin production plants, resulting in a narrow range of applications; and conventional modification methods, due to their simple equipment and production processes, cannot meet the complex injection molding requirements of products. Furthermore, with increasing societal focus on environmental protection and sustainable development, higher demands are being placed on the performance, service life, and environmental compatibility of plastic materials. In the air conditioning industry, fan blades, as key components, have stringent standards regarding material strength, impact resistance, toughness, and environmental friendliness. While traditional engineering plastics PC with added glass fiber meet some performance requirements to a certain extent, their cost is high, and there is room for improvement in energy conservation and emission reduction. Summary of the Invention

[0004] The purpose of this invention is to provide a flame-retardant AS+ glass fiber alloy material that achieves the goals of cost reduction and efficiency improvement, energy conservation and emission reduction, green environmental protection and sustainable development, and significantly enhances the competitiveness of the product in the market.

[0005] To achieve the above objectives, the present invention provides the following technical solution.

[0006] An AS-modified plastic with glass fiber comprises the following raw materials: AS base material, glass fiber, antioxidant, heat stabilizer and lubricant, in proportions of 80-90%, 10-20%, 1-2%, 1-2% and 1-2%, respectively.

[0007] The AS base material is general-purpose plastic and / or engineering plastic;

[0008] The method for preparing the modified plastic includes the following steps:

[0009] A1. Accurately weigh the raw materials according to the proportion, add them to a high-speed mixer and mix for 8-25 minutes at a mixing speed of 1300-1500 rpm;

[0010] A2. The uniformly mixed raw materials are fed into a twin-screw extruder for melt blending and extrusion. The extrusion temperature is 170-200℃ and the screw speed is 400-450 rpm.

[0011] A3. The extruded strips are cooled with water and pelletized to obtain AS-modified plastic particles with glass fiber.

[0012] Preferably, the antioxidant is KUV-B900.

[0013] Preferably, the lubricant is PETS, and the amount added is controlled between 1% and 5%.

[0014] Preferably, the AS base material includes general-purpose plastics and / or engineering plastics.

[0015] Compared to traditional PC+glass fiber materials, the AS+glass fiber modified plastic formula of this invention significantly reduces raw material costs, effectively alleviating the pressure on downstream home appliance industries caused by rising costs and improving the economic benefits of enterprises. At the same time, through the reasonable proportion of glass fiber, antioxidants, heat stabilizers and lubricants, the material exhibits excellent performance in terms of strength, impact resistance, toughness, oxidation resistance and thermal stability.

[0016] This invention is recyclable, conforms to the concepts of green environmental protection and sustainable development, and helps to promote the entire industry towards a more environmentally friendly direction.

[0017] Compared with the prior art, the AS+ glass fiber modified material of the present invention has the following advantages:

[0018] 1. Cost is significantly reduced compared to the traditional PC+GF system; 2. Excellent overall performance in terms of mechanical and processing properties; 3. High heat distortion temperature, meeting the requirements for fan blade use; 4. Environmentally friendly, recyclable materials, supporting green manufacturing. Attached Figure Description

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1This embodiment provides an AS-modified plastic with glass fiber, comprising the following raw materials: AS base material, glass fiber, antioxidant, heat stabilizer and lubricant 1-2%, in proportions of 80-90%, 10-20%, 1-2%, 1-2% and 1-2%, respectively.

[0024] The preparation method includes the following steps:

[0025] A1: After accurately weighing the above raw materials according to the proportion, add them to a high-speed mixer for thorough mixing. The mixing time is 10 minutes and the mixing speed is 1500 rpm.

[0026] A2: After mixing evenly, add the material to a twin-screw extruder for melt blending and extrusion. Set the extruder temperature to between 170-200 degrees Celsius and the screw speed to 430 rpm.

[0027] A3: The extruded strips are cooled with water and granulated to obtain AS-modified plastic particles with glass fiber.

[0028] Preferably, the AS base material includes general-purpose plastics and / or engineering plastics.

[0029] The obtained material was injection molded into standard test strips, and its performance was tested in accordance with GB / T 1040.2, GB / T 1843, and GB / T 1634 standards.

[0030] project Test Standards Test Results Tensile strength GB / T 1040.2 55MPa Impact strength GB / T 1843 <![CDATA[5.2kJ / m 2 ]]> Heat distortion temperature GB / T 1634 230℃ Oxidation induction time GB / T 19466 ≥20 minutes

[0031] This material meets the requirements of air conditioner fan blades for strength, toughness, heat resistance, and processability, and is recyclable, effectively reducing production energy consumption and carbon emissions.

[0032] Example 2

[0033] Based on Example 1, the glass fiber content was adjusted to 18%, the lubricant was controlled at 2%, and the other proportions remained unchanged. The resulting particles exhibited the following characteristics in the fan blade injection molding test:

[0034] It has good molding fluidity;

[0035] The yield rate increased by approximately 8%;

[0036] The overall air resistance and energy efficiency test data are qualified.

[0037] As can be seen from the above Examples 1 and 2, this material is suitable for high-strength injection molded products and has significant advantages such as low cost, high performance and green environmental protection. It is especially suitable for replacing traditional PC+GF materials for household appliance structural parts.

[0038] Furthermore, the AS base material uses general-purpose plastics and engineering plastics as raw materials, which work synergistically to provide good basic properties for the modified plastic. The content ranges from 80% to 90%, and in this embodiment, general-purpose plastic AS is used.

[0039] Glass fiber, as a reinforcing material, can effectively improve the key properties of plastics such as strength, impact resistance, and toughness. Extensive experimental research has determined that the optimal glass fiber content range is 10%-20%. Within this range, the material can achieve excellent mechanical properties while maintaining good processing flowability, meeting the requirements of air conditioner fan blade injection molding.

[0040] Antioxidants can effectively inhibit the oxidative degradation of plastics during processing and use, extending the service life of the materials. After screening and experimental verification, KUV-B900, an anti-aging agent, was selected as the antioxidant, and its addition amount of 1%-2% can significantly improve the antioxidant performance of the material.

[0041] Lubricants can improve the processing fluidity of materials, reduce friction during processing, increase production efficiency, and ensure product quality. This invention uses PETS lubricant, with the addition amount controlled at 1%-5%, which allows the material to smoothly fill the mold cavity during injection molding, reducing product defects.

[0042] After preparation, the obtained particles were injection molded into standard specimens, and performance tests were conducted according to relevant standards. The test results showed that the tensile strength of the material reached 50 mm / min MPa, and the impact strength was 5 kJ / m. 2 The material exhibits a heat distortion temperature of 230℃ and good oxidation resistance. After passing a test at 23℃ under simulated operating conditions, its performance remained stable. When used in the production of air conditioner fan blades, the product quality was satisfactory, and the production process proceeded smoothly.

[0043] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific embodiments of the present invention are limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered to fall within the patent protection scope defined by the submitted claims.
