Polyamide composite material and preparation method thereof

Abstract

The invention discloses a polyamide composite material. The polyamide composite material comprises the following components in parts by weight: 60 to 98 parts of polyamide, 0.5 to 40 parts of fillingmaterial and 0.5 to 10 parts of other aids. The invention also provides a preparation method of the polyamide composite material. The preparation method of the polyamide composite material comprises the following steps: selecting the raw materials according to the above components and the weight percentage, mixing the polyamide and other aids uniformly by a mixing machine, adding the mixture intoa double-screw extruding machine, mixing, adding the filling material through lateral feeding, extruding material strips, cooling by a water channel, granulating by a granulating machine, drying by adrying machine and packaging to obtain finished products. The obtained finished products show excellent low-temperature resistance on the premise of meeting long-time use of the materials, can be usedin various complex environments, and solves the problems in the prior art that the polyamide composite material and plastic pipe fittings made thereby are influenced by the environment temperature greatly, particularly at low temperature, the lower the temperature is, the lower the toughness is, and the materials are liable to embrittle, break and damage.

Description

technical field [0001] The invention relates to a resin composite material and a preparation method thereof, in particular to a polyamide composite material and a preparation method thereof. Background technique [0002] Water is the source of life, and the quality of drinking water is closely related to people's health. After years of publicity and popularization of drinking water and health knowledge, people have gradually understood the impact of water quality on human health, and paid more attention to drinking water safety, which provides a great market prospect for water purifier products. [0003] Once the water purifier is turned on, water will accumulate inside it, and the accumulated water will not be discharged: so in the cold season, the water purifier is often in an environment below 0°C. As the temperature drops, the water in the filter bottle and other plastic pipe fittings The water in the water gradually freezes and expands, and the expansion to a certain e...
