Low-cost warping-free high-flame-retardant polypropylene furniture material and preparation method thereof

Abstract

The invention discloses a low-cost warping-free high-flame-retardant polypropylene furniture material, prepared from the following components according to a weight ratio: 20-50 percent of polypropylene, 15-35 percent of short glass fiber organic masterbatch, 5-10 percent of flexibilizer, 25-35 percent of nano calcium carbonate and 0.1-1 percent of lubricant; the short glass fiber organic masterbatch is formed by short glass fiber, intumescent flame retardants, a coupling agent of organic titanate and polyethylene wax. Organized modification is performed on the short glass fiber, the surface of the short glass fiber is coated with the coupling agent, the flame retardants and an organic polymeric membrane, so that the compatibility between the short glass fiber and the interface of polypropylene resin can be effectively improved, the uniform dispersion of the glass fiber and the flame retardants is promoted, the warping problem caused by stress is prevented, the mechanical property and flame retardance are improved, the filling content of the short glass fiber is increased, and the product cost is lowered.

Description

technical field [0001] The invention relates to an organic polymer nanocomposite material, more specifically, to a low-cost, non-warping, high-flame-retardant polypropylene furniture material and a preparation method thereof. Background technique [0002] Plastic furniture is a new kind of furniture, which has occupied a very important position in people's daily life. Compared with other furniture, plastic furniture has the advantages of 1) brilliant colors and smooth lines; 2) diverse and casual and beautiful shapes; 3) light, compact and easy to take; 4) various varieties and wide application; 5) easy to clean and easy to protect; 6) cheap And so on a series of advantages. Because plastic furniture has such obvious advantages, it has rapidly occupied the market share in the furniture field in recent years. But at present, my country's domestic plastic furniture mainly occupies the middle and low-end market in the mainstream furniture market. This is not only because of s...

AI Technical Summary

Problems solved by technology

Adding other high-performance polymer materials to the polypropylene resin can improve the performance of the polypropylene system, but the cost is often high, and it is difficult to promote in furniture products

Adding inorganic nanoparticles such as glass fiber and calcium carbonate to polypropylene resin (the price is relatively low compared to polypropylene) can improve the mechanical properties of polypropylene material and control its cost to a certain extent, but due to the relative Poor capacity, if the addition amount is large (greater than 30%), it is easy to form phase separation or stress concentration, which will affect the mechanical properties and appearance of the polypropylene system, and cannot meet the performance requirements of household materials

At present, domestic and foreign patents and technologies are difficult to meet the needs of high-end polypropylene furniture materials (good performance, no warping, low cost)
