Problems solved by technology

First of all, cast iron manhole covers are easy to rust, break and be stolen, and their appearance is unattractive and rusty; secondly, the quality of RMC molded manhole covers and cement manhole covers often fails to meet the load-bearing requirements, and the color of the manhole covers is too single. It is extremely distorted and easy to fade, and it is impossible to achieve personalized design as one likes; in addition, although the FRP manhole cover solves the problem of load bearing, due to its high production cost, the upper surface is not wear-resistant and other shortcomings are not conducive to practical application

Embodiment 1

[0018] see figure 1 , The present embodiment consists of a core body 1, a network frame 2, a reinforcement layer 3, a color layer 4, a color isolation layer 5, and a color layer 6. The grid frame 2 is coated on the outer surface of the core body 1, the outer layer of the grid frame 2 covers the reinforcing layer 3, the color layer 4 is coated on the upper surface of the reinforcing layer 3, the upper surface of the color layer 4 is covered with a color layer 6, and the color isolation layer 5 It is arranged between the color layer 4 and the color layer 6 . The reinforcement layer 3 is 20mm thick, the color layer 4 is 10mm thick, and the color layer 6 is 4mm thick. Its production process is (a): the preparation of resin: add 1000 kilograms of marble resins into the raw material pool, and add 4 kilograms of cobalt isooctanoate accelerators, fully stir evenly, make the accelerators completely and evenly dispersed in the resin, and set aside; (b ) Preparation of color paste: in ...

Embodiment 2

[0020] see figure 2 , this embodiment includes a core body 1, a network frame 2, a reinforcement layer 3, and a color layer 4. The network frame 2 is a reinforced steel network frame and a fiber prepreg network frame, and is coated on the exterior of the core body 1. On the network frame 2 The outer layer of the reinforcement layer covers the reinforcement layer 3, and the color layer 4 is coated on the upper surface of the reinforcement layer 3. The reinforcement layer 3 is 8mm thick, and the color layer 4 is 9mm thick. The 4 components of the color layer are proportioned by weight: for every 100 kilograms of resin A, add 0.8 kilogram of cyclohexanone peroxide curing agent, and then add 150 kilograms of agate powder and glass microsphere mixture to this mixture, wherein resin A The ratio is: 191 per 100 kg # Unsaturated polyester resin is mixed with 2 kilograms of cobalt naphthenate accelerator.

[0021] The production process is as follows: (a): preparation of resin A: f...

Embodiment 3

[0023] Referring to FIG. 3 , this embodiment includes a core body 1 , a network frame 2 , a reinforcement layer 3 , a color layer 4 and a color layer 6 . The grid frame 2 is a reinforced grid frame and a fiber prepreg grid frame, and is coated on the outside of the core body 1, and the outer layer of the grid frame 2 is covered with a reinforcement layer 3, and the color layer 4 is coated on the upper surface of the reinforcement layer 3 , the upper surface of the color layer 4 is covered with the color layer 6 . The reinforcement layer 3 is 10mm thick, the color layer 4 is 15mm thick, and the color layer 6 is 1mm thick. The proportioning of the color layer components is as follows: every 100 kilograms of resin A, add 0.5 kilogram of methyl ethyl ketone peroxide curing agent, then add 280 kilograms of colored stone powder and agate powder mixture in this mixture, wherein the proportioning of resin A is : 191 per 100 kg # The resin is mixed with 0.9 kg of cobalt isooctanoate ...

Abstract

The invention discloses a multicolor composite material well cover and production process thereof, comprising: core body, network frame, enhancing layer, color layer. The outer layer of the network frame coats the outer surface of the core body and the enhancing layer on the outer surface of the network frame. The color layer coats on the upper surface of the enhancing layer. The proportion of the color layer components by weight is that: adding 0.1-1 portion by weight of solidifying agent in 100 portion by weight of resin A, then adding 50-300 portion by weight of colorful stone powder and / or agate powder and / or glass micro bead into the mixture, in which the proportion of the resin A is that: adding 0.4-2.5 portion by weight of accelerant in 100 portion by weight of unsaturated polyester resin. The inventive multicolor composite material well could adopt a plurality of colors for a personalized design.

Description

technical field [0001] The invention relates to an inspection well cover, in particular to a multi-color composite material well cover and its production process. Background technique [0002] At present, there are many types of manhole covers on the market, including cast iron manhole covers, RMC molded manhole covers, cement manhole covers, and fiberglass manhole covers. They are more or less defective in quality and appearance. First of all, cast iron manhole covers are easy to rust, break and be stolen, and their appearance is unattractive and rusty; secondly, the quality of RMC molded manhole covers and cement manhole covers often fails to meet the load-bearing requirements, and the color of the manhole covers is too single. It is extremely distorted and easy to fade, and can not be customized as one likes. In addition, although the FRP manhole cover solves the load bearing problem, it is not conducive to practical application due to its high production cost and non-we...
