Problems solved by technology

Now the flame-retardant safety dense mesh materials used in buildings are pp and hdpe. The biggest disadvantage of the dense mesh made of these two materials is that the flame retardant is an inorganic additive, the anti-aging time is short, and the impact resistance is weak. After 3-6 months of outdoor wind and sun, the flame retardant precipitates, the flame retardant effect weakens, the product ages, and the impact force is significantly reduced, bringing invisible safety hazards to the construction site

Embodiment 1

[0040] The raw material of polyester flame-retardant dense mesh is primary plastic particles high-density polyethylene or recycled materials for mineral water bottle cap materials. The raw materials are processed and crushed with a plastic crusher, and the crushed polyester bottle flakes are placed in a high-temperature washing machine at high temperature. Cleaning, the bacteria and microorganisms of the polyester bottle flakes, so as to improve the anti-corrosion ability, after the sterilization is completed, the polyester bottle material is dried, dried with a centrifugal device, and then dried by a drying device. After drying, the Put 85% polyester bottle flakes, 1% anti-aging agent, 2% reinforcing agent, and 5% flame retardant into the mixer, stir evenly to form a recycled polyester flame retardant solution, and use the wire drawing machine screw to make the recycled polyester flame retardant The solution is extruded by a screw, and passed through the spinning reaction equi...

Embodiment 2

[0045] Embodiment 2 is basically the same as Embodiment 1, the only difference is: the proportion of regenerated polyester flame retardant solution,

[0046] According to the distribution percentage table of the regenerated polyester flame retardant solution corresponding to Example 2, put in the materials, and use a mixer to stir evenly to form a regenerated polyester flame retardant solution.

Embodiment 3

[0048] Embodiment 3 is basically the same as Embodiment 1, the only difference is: the proportion of regenerated polyester flame retardant solution,

[0049] According to the distribution percentage table of the regenerated polyester flame retardant solution corresponding to Example 3, put in the materials, and use a mixer to stir evenly to form a regenerated polyester flame retardant solution.

Abstract

The invention discloses a polyester flame-retardant dense screen production process. The process comprises the steps of polyester bottle smashing, high-temperature cleaning, spin-drying, blending, screw extrusion spinning, cold drawing, high-temperature sizing, beam warping, screening machine molding, piece-cutting and mesh edge sealing, and finished product packaging. The process has the beneficial effects of simple structure and high practicability.

Description

technical field [0001] The invention relates to a flame-retardant polyester safety dense mesh and a flame-retardant polyester sunshade net for buildings, in particular to a production process of the polyester flame-retardant dense mesh. Background technique [0002] The earliest safety mesh used in construction was non-flame retardant. Later, it was stipulated by the state that the flame retardant dense mesh used in construction must be flame retardant to meet the fire protection standard. The materials used are pp and hdpe. Now the flame-retardant safety dense mesh materials used in buildings are pp and hdpe. The biggest disadvantage of the dense mesh made of these two materials is that the flame retardant is an inorganic additive, the anti-aging time is short, and the impact resistance is weak. After 3-6 months of outdoor wind and sun, the flame retardant precipitates, the flame retardant effect weakens, the product ages, and the impact force is significantly reduced, brin...
