Bonding modified polypropylene material special for refrigerator

The invention discloses a bonding modified polypropylene material special for a refrigerator, and belongs to the field of plastic processing. The special material comprises the following components by weight percent: 25-40% of mineral filler, 0.5-2% of a compatilizer, 0.8% of a lubricant, 0.2% of an antioxidant and the balance of a polypropylene base material. The polypropylene base material consists of homo-polypropylene granules and homo-polypropylene powder; and the weight ratio of the homo-polypropylene granules to the homo-polypropylene powder is (24-55):15. The mineral filler is superfine talcum powder with the average granule size of 2.6-3.5 microns, and the superfine talcum powder is subjected to bonding modification surface treatment. The special material has high tensile strength and anti-impact strength, and performances such as elongation at break, bending strength, flexural modulus and heat distortion temperature of the material can all satisfy the application requirements of the refrigerator; an
