Problems solved by technology

Traditional rubber and plastic insulation materials and installation methods still have some defects: 1. On-site suit construction is inconvenient, resulting in loose fit and affecting the insulation effect; 2. Rubber and plastic materials are easy to absorb moisture and have poor insulation effects, and are prone to aging and short service life; 3. , There is no protective layer on the surface, and it is easy to scratch when passing through the wall
[0004] The PPR thermal insulation composite pipe for home decoration disclosed in the above patent mainly solves the problems of scratch resistance, easy deformation of the thermal insulation layer and poor thermal insulation effect caused by aging, rather than improving the thermal insulation performance of the thermal insulation layer itself. Therefore, its thermal insulation effect still needs to be improved.

Embodiment 1

[0029] The home decoration composite pipe of this embodiment comprises a hollow pipe body 1 of PPR material, an insulation layer 2, a PIR layer and a protective layer 3 of a galvanized sheet arranged in sequence from the inside to the outside, and the insulation layer 2 includes the following parts by weight Preparation raw materials: 52 parts of diatomite, 12 parts of vermiculite powder, 23 parts of water-based polyurethane resin, 5 parts of magnesium oxide, 5 parts of carboxymethyl cellulose, 3 parts of 11 μm hollow glass microspheres and foaming agent (sodium bicarbonate and citric acid in a weight ratio of 1:1) 5 parts. The thickness ratio of the hollow pipe body, insulation layer, protective layer and PIR layer is 5:2:6:2. The particle size of diatomite is controlled to be 1000 mesh; the particle size of magnesium oxide, carboxymethyl cellulose and foaming agent are all controlled to be 800 mesh; the particle size of vermiculite powder is all controlled to be 150 mesh.

Embodiment 2

[0035] Only the "insulation layer" includes the following preparation raw materials in parts by weight: 58 parts of diatomite, 15 parts of vermiculite powder, 30 parts of water-based polyurethane resin, 8 parts of magnesium oxide, 8 parts of carboxymethyl cellulose, and 7 parts of hollow glass microspheres of 17 μm 8 parts and foaming agent (the mixture of sodium bicarbonate and citric acid mixed in a weight ratio of 1:1). The ratio of the thickness of the hollow tube body, insulation layer, protective layer and PIR layer is 7:5:8 : 3." Different from Example 1, others are the same as Example 1.

Embodiment 3

[0037] Only "the insulation layer includes the following preparation raw materials in parts by weight: 55 parts of diatomite, 14 parts of vermiculite powder, 26 parts of water-based polyurethane resin, 6 parts of magnesium oxide, 6 parts of carboxymethyl cellulose, 6 parts of hollow glass microspheres of 16 μm 6 parts and foaming agent (the mixture of sodium bicarbonate and citric acid mixed in a weight ratio of 1:1). The ratio of the thickness of the hollow tube body, insulation layer, protective layer and PIR layer is 6:3:7 : 2." Different from Example 1, others are the same as Example 1.

Abstract

The invention relates to a composite pipe for home improvement, which comprises a hollow pipe body, a thermal insulation layer and a protective layer arranged sequentially from the inside to the outside, and the thermal insulation layer includes the following preparation raw materials in parts by weight: 50-60 parts of diatomite, leech 10-15 parts of stone powder, 20-30 parts of water-based polyurethane resin, 5-10 parts of magnesium oxide, 5-10 parts of carboxymethyl cellulose, 3-8 parts of hollow glass microspheres and 5-8 parts of foaming agent. The home decoration composite pipe of the invention has good thermal insulation performance.

Description

technical field [0001] The invention relates to pipeline technology, in particular to a composite pipe for home decoration. Background technique [0002] Modern home improvement pays more and more attention to the safety, comfort and energy-saving effect of pipeline concealed installation projects. For example, the insulation and energy saving of daily hot water pipes, the anti-freezing and cracking of pipes in winter, and the anti-condensation of pipes in high-temperature and high-humidity environments in southern summer all urgently require the development and application of thermal insulation composite pipes. In some suspended ceilings and outdoor surface installation conditions, pipes are required to be weather-resistant, scratch-resistant and rigid at the same time. Traditional rubber and plastic insulation materials and installation methods still have some defects: 1. On-site suit construction is inconvenient, resulting in loose fit and affecting the insulation effect...
