Introduction

Hello everyone, welcome to today’s popular science lecture. Today we are going to talk about a topic that sounds a bit professional but is actually very interesting and practical – the application of polyurethane sponge antistatic agents in the construction of stadiums. You may wonder, what is polyurethane sponge antistatic agent? What does it have to do with stadiums? Don’t worry, next I will use easy-to-understand language to take everyone to unveil this mystery.

What is polyurethane sponge antistatic agent?

Basic concept of polyurethane sponge

First of all, we need to understand what a polyurethane sponge is. Polyurethane sponge is a polymer material with light weight, softness and good elasticity. It is widely used in furniture, car seats, mattresses and other fields. In sports venues, polyurethane sponges are often used to make sports floor mats, seats, protective pads, etc.

The function of antistatic agents

So, what are antistatic agents? Simply put, antistatic agents are chemicals that can reduce or eliminate static accumulation on the surface of a material. Static accumulation will not only affect the performance of the material, but may also cause safety hazards. In sports stadiums, static electricity accumulation may lead to equipment failures, athlete injury and other problems. Therefore, the application of antistatic agents is particularly important.

Application of polyurethane sponge antistatic agent in sports venues

Sports floor mat

Why do you need antistatic agents?

Sports floor mats are an indispensable part of stadiums. Whether it is a basketball court, a badminton court or a gym, the floor mats can provide good cushioning and anti-slip effects. However, traditional floor mats are prone to static accumulation during use, which not only affects the athlete’s performance, but may also cause equipment failure.

Application of antistatic agents

The electrostatic accumulation on the floor mat surface can be effectively reduced by adding antistatic agent to the polyurethane sponge. This not only improves the service life of the floor mat, but also ensures the safety of athletes. Here are some common antistatic agent parameters:

Antistatic agent type	Additional amount (%)	Effect duration (month)	Applicable temperature range (℃)
Ion type	0.5-1.5	6-12	-20 to 60
Nonionic	1.0-2.0	12-24	-30 to 80
Composite	0.8-1.8	18-36	-40 to 100

Seats and protective pads

Antistatic requirements for seats

Seats in stadiums are usually made of polyurethane sponge, which is comfortable and durable. However, the seats can also generate static electricity accumulation during use, especially in dry environments. This will not only affect the audience’s comfort, but may also cause safety risks.

Antistatic requirements for protective pads

Protective pads are mainly used to protect athletes from impact injuries. However, traditional protective pads are prone to static accumulation during use, which not only affects the protection effect, but may also cause equipment failure.

Application of antistatic agents

The electrostatic accumulation on the seat and protective pad surfaces can be effectively reduced by adding antistatic agents to the polyurethane sponge. This not only improves the service life of the seats and protective pads, but also ensures the safety of the audience and athletes. Here are some common antistatic agent parameters:

Antistatic agent type	Additional amount (%)	Effect duration (month)	Applicable temperature range (℃)
Ion type	0.5-1.5	6-12	-20 to 60
Nonionic	1.0-2.0	12-24	-30 to 80
Composite	0.8-1.8	18-36	-40 to 100

Advantages of polyurethane sponge antistatic agent

Improving durability
