Problems solved by technology

Traditional waterproofing membranes are mainly based on ordinary thermoplastic polyolefin and polyvinyl chloride. Although these materials have certain price advantages, they are prone to aging, degradation and volatilization of harmful gases in long-term use, especially when waterproofing membranes More susceptible to degradation when exposed to certain environmental conditions such as UV radiation and high temperature
In addition, due to the increase of acid pollutants in the air, when the waterproof membrane is exposed to polluted acid rainwater, the life and aging performance of the waterproof membrane will also be reduced.

Embodiment

[0031] This embodiment provides a kind of TPO / functional masterbatch composite waterproof membrane particles for construction. Firstly, the formula of component B functional masterbatch is provided, which includes the following components in parts by weight:

[0032]

[0033] Among them, the light stabilizer used is Japan's ADK company's ultraviolet absorber LA-32 and hindered amine light stabilizer LA-402AF compounded according to the weight ratio of 1:2; the antioxidant is ADK company's hindered phenol AO-60 and sub- Phosphate ester HP-10 is compounded according to the weight ratio of 1:1.2; processing aids are NA-11 and AX-71 of ADK Company.

[0034] TPO resin is selected from BASF CA10A.

[0035] The polyethylene resin is linear low-density polyethylene (LLDPE), its melt index is 0.8-2.5g / 10min, Zhenhai Refining & Chemical DFDA-7042.

[0036] Ethylene-vinyl acetate copolymer resin (EVA), with a content of 28 EVA, has good high and low temperature resistance.

[0037] ...

Embodiment 6

[0054] This embodiment provides a kind of waterproof membrane particle, and its difference with embodiment 1 is only, in raw material composition, also added the lubricant of 0.6 weight part, and lubricant is NA-11 and AX-71 that ADK company produces .

Abstract

The invention provides waterproof roll particles as well as a preparation method and application thereof. The waterproof roll particles are prepared from a component A and a component B in a weight ratio of 7: 1 to 4.5: 1 through mixed granulating or mixed blending and extruding, wherein the component A is TPO resin, and the component B is a functional master batch. The invention further providesa preparation method and application of the waterproof roll particles. The waterproof roll particles have the advantages of good ultraviolet resistance, excellent weather resistance, stable color andeasiness in extrusion processing.

Description

technical field [0001] The invention relates to a waterproof membrane particle and a preparation method thereof, belonging to the technical field of compositions. Background technique [0002] Waterproof membrane is a kind of building material commonly used in construction facilities. With the development of urbanization, various buildings have higher and higher requirements for waterproof membrane. Traditional waterproofing membranes are mainly based on ordinary thermoplastic polyolefin and polyvinyl chloride. Although these materials have certain price advantages, they are prone to aging, degradation and volatilization of harmful gases in long-term use, especially when waterproofing membranes Degradation is more likely to occur when exposed to certain environmental conditions such as UV radiation and high temperature. In addition, due to the increase of acid pollutants in the air, when the waterproof membrane is exposed to polluted acid rainwater, the life and aging perfo...
