Background
Most of the existing large lamp assemblies are made of nylon materials, the water absorption rate of the nylon materials is 9-12%, so that the interior of the large lamp is easy to fog in the using process, and the lighting effect of the light is greatly influenced.
The Polycarbonate (PC) is an amorphous polymer, has excellent performance, has tough and rigid mechanical characteristics, and has the outstanding characteristics of high impact resistance and creep resistance, good dimensional stability, good cold resistance, high unnotched impact strength, high initial position in engineering plastics, high glass transition temperature, continuous use within the range of 120 plus 130 ℃, good electrical insulation and good dimensional stability; however, PC has many disadvantages, such as poor flowability, difficult processing into thin-walled parts, easy stress cracking, poor solvent resistance and wear resistance, low notch impact strength, etc., so it is necessary to improve the properties of the plastic products for practical use.
Polybutylene terephthalate (PBT) is crystalline thermoplastic resin, has high crystallization speed, excellent creep resistance, good oil resistance and melt fluidity, is stable to alcohols, ethers, high molecular weight esters, aliphatic hydrocarbons and the like, and has strong stress cracking resistance. Therefore, the PC/PBT alloy material obtained by blending PC and PBT can make up for deficiencies of PC in chemical resistance, molding processability and wear resistance, and can overcome the defects of poor heat resistance and low notch impact strength of PBT, namely the PC/PBT alloy material has excellent processing fluidity, low-temperature impact resistance, good chemical reagent resistance and weather resistance, and certain properties are specifically improved by adding an auxiliary agent, so that a plastic alloy material with excellent properties, strong pertinence and good practicability can be obtained.
With such good expectations, much research has been done on the modification of PC/PBT alloy materials. For example, the chinese invention patent discloses a PC/PBT alloy material, and a preparation method and application thereof [ application number: 201410815771.6], the PC/PBT alloy material comprises 50-70 parts of PC, 20-30 parts of PBT, 2-6 parts of SEBS, 5-15 parts of a toughening agent, 0.5-2 parts of a compatilizer, 0.8-2 parts of an ester exchange inhibitor, 0.1-1 part of an antioxidant and 0.1-1 part of a lubricant, wherein the toughening agent is a polysiloxane-methyl methacrylate copolymer, the compatilizer is SBS-MAH, the ester exchange inhibitor is a phosphoric acid ester exchange inhibitor, the antioxidant is a hindered phenol antioxidant or a phosphite antioxidant, the lubricant is silicone powder, the mass content of styrene in the SEBS is 15-65%, the particle size of the polysiloxane-methyl methacrylate copolymer is 90-200 nm, and the PC/PBT alloy material provided by the invention has high impact resistance and notch impact strength.
For example, the chinese invention patent discloses a high-toughness flame-retardant PBT/PC composite material [ application number: 201310252887.9], the PC/PBT alloy material provided by the invention has higher heat distortion temperature and better flame retardant property.
Therefore, the strength, impact resistance, flame retardance and the like of PC/PBT alloy materials are researched more, but the water absorption, antifogging performance and the like of the materials are still researched less.

Detailed Description
The reagents used in the following examples, unless otherwise specified, were purchased from conventional biochemical reagent stores.
Example 1
The embodiment provides a fogging-resistant and water-absorption-resistant headlamp assembly material, and specifically the fogging-resistant and water-absorption-resistant headlamp assembly material comprises, by mass, 80 parts of a PBT resin, 20 parts of a PC resin, 8 parts of a compatilizer, 30 parts of nano scandium oxide, 10 parts of sorbose, 10 parts of an MBS resin and 0.5 part of a nucleating agent.
Wherein, the compatilizer is a maleic anhydride graft copolymer which takes POE resin as matrix resin and has the maleic anhydride grafting rate of 1.0 percent, and the nucleating agent is a mixture formed by mixing 1, 3, 5-tri-tert-butyrylaminobenzene and tri-tert-butyramide trimesic acid according to the mass ratio of 1: 1.
The main components of the headlamp component material are PBT resin and PC resin, although the PBT resin and the PC resin have similar chemical structures and certain compatibility, the PBT resin is a crystalline polymer, and the PC resin is an amorphous polymer, and the PBT/PC alloy obtained by blending the PBT resin and the PC resin belongs to a typical crystalline/amorphous polymer blending system, the interface bonding is poor, the impact strength is low, namely, the PBT resin and the PC resin are simply melt blended, the effect is strong, and the layering phenomenon even occurs under certain conditions. The compatibilizer is also called a compatibilizer, and refers to an aid which promotes incompatible two polymers to be combined together by virtue of intermolecular bonding force, so as to obtain a stable blend. After the compatilizer is added, the effects of (1) reducing the surface tension between two polymers, promoting the dispersion of phases and preventing the parallel connection of dispersed phases can be achieved; (2) the thickness of the interface layer is increased, the bonding force among the phases is increased, the thermal stability is improved, and the stress transfer efficiency is increased; (3) the particle size of the dispersed phase is reduced, a stable phase structure is formed, and the effect of uniform and stable performance is provided for the material.
POE is thermoplastic elastomer of ethylene and octene in situ polymerization, and is characterized in that: (1) the soft chain curling structure of the octene and the crystallized ethylene chain are used as physical crosslinking points, so that the octene has excellent toughness and good processability; (2) the POE plastic has no unsaturated double bonds in the molecular structure and has excellent aging resistance; (3) the POE plastic has narrow molecular weight distribution, better fluidity and good compatibility with polyolefin; (4) the good fluidity can improve the dispersion effect of the filler and simultaneously can improve the weld mark strength of the product. The maleic anhydride graft copolymer with POE as matrix resin introduces strong polar side group on the nonpolar molecular main chain, so that the copolymer can be used as a bridge for improving the adhesion and compatibility of polar materials and nonpolar materials, and can be used as a good toughening agent and a good compatilizer.
Scandium oxide has the chemical formula Sc2O3The scandium oxide is a white solid, has a cubic structure of rare earth sesquioxide, has a higher melting point, obviously improves the thermal deformation temperature of the scandium oxide after being filled in the scandium oxide nano-scale scandium oxide nano.
Sorbose is monosaccharide ketose which is white crystal or crystalline powder, sorbose has 5 hydroxyl groups and is strong in polarity, water absorption of a high polymer material is caused by strong interaction between polar groups on the high polymer and water, and after sorbose is added, interaction between the polar groups on the high polymer and the interior of the material is strengthened, interaction between the high polymer and the water is weakened, and therefore water absorption of the material is reduced.
The MBS resin is a terpolymer of methyl methacrylate, butadiene and styrene, has a typical core-shell structure, and can play a role in toughening and modifying when used in PC/PBT alloy.
The trimesic acid tri-tert-butanamide and the 1, 3, 5-tri-tert-butanamidobenzene are nucleating agents, the mechanisms of the two nucleating agents are the same, and the two nucleating agents are dissolved in the molten polycarbonate to form a homogeneous solution, so that the nucleating agents are firstly crystallized to form a fibrous network when the polycarbonate is cooled, the network is uniformly dispersed, and a crystal nucleation center is formed on the surface of the network, so that the crystallization behavior of the polycarbonate material can be changed, the crystallization rate is accelerated, the crystallization density is increased, the grain size is refined, and the light transmittance of the material can be improved due to the refined grain size.
