A high heat resistant fiber reinforced hdpe plastic outdoor table and its manufacturing method

Abstract

The invention discloses a high-heat-resistant fiber reinforced HDPE plastic outdoor table and a production method thereof. The high-heat-resistant fiber reinforced HDPE plastic outdoor table comprises an HDPE base material containing the following components: 90-100 parts of HDPE, 8-15 parts of a PP copolymer, 12-18 parts of glass fiber, 9-12 parts of talcum powder, 0.2-0.5 part of an anti-ultraviolet ray agent and 0.1-0.3 part of other additives. The high-heat-resistant fiber reinforced HDPE plastic outdoor table comprises a breathable waterproof layer, a high-temperature-resistant polypropylene non-woven cloth layer, an anti-aging sealing plastic layer, a plurality of fiber reinforced layers and an HDPE table top plate, wherein the breathable waterproof layer is arranged outside the high-temperature-resistant polypropylene non-woven cloth layer in a wrapping manner; the high-temperature-resistant polypropylene non-woven cloth layer is arranged outside the anti-aging sealing plastic layer in the wrapping manner; the anti-aging sealing plastic layer is arranged outside the HDPE table top plate in a sealing and wrapping manner; the fiber reinforced layers are arranged inside the HDPE table top plate. The environment cracking-resistance of the HDPE plastic outdoor table is remarkably improved, the pressure and impact resistance is enhanced, meanwhile the high heat resistance of the HDPE plastic outdoor table is greatly improved, the structural stability of the HDPE plastic outdoor table is maintained, the service life is prolonged, and popularization and application are facilitated.

Description

【Technical field】 [0001] The invention relates to the technical field of plastic table manufacturing, in particular to the technical field of a high heat-resistant fiber-reinforced HDPE plastic outdoor table and a manufacturing method thereof. 【Background technique】 [0002] High-density polyethylene, referred to as "HDPE", is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and the thin section is translucent to a certain extent. PE has excellent resistance to most domestic and industrial chemicals. HDPE is a highly crystalline, non-polar thermoplastic resin. High-density polyethylene is a white powder granular product, non-toxic and tasteless, with a density in the range of 0.940-0.976g / cm3; a crystallinity of 80%-90%, a softening point of 125-135°C, and a service temperature of up to 100 ℃; melting temperature 120 ~ 160 ℃. It has good heat resistance and cold resistance, good chemical stability, high rigidity and...

AI Technical Summary

Problems solved by technology

Hardness, tensile strength and creep are better than low-density polyethylene; wear resistance, electrical insulation, toughness and cold resistance are better, but slightly worse than low-density insulation; chemical stability is good, at room temperature Under certain conditions, it is insoluble in any organic solvents, corrosion-resistant to acids, alkalis and various salts; it has low permeability to water vapor and air, and low water absorption; it has poor aging resistance, and its environmental crack resistance is not as good as that of low-density polyethylene, especially It is thermal oxidation that will reduce its performance, and the heat distortion temperature of high-density polyethylene under stress is low

Plastic outdoor tables are bound to be stressed during use, and are easily deformed by heat during this process due to the above reasons
