Abstract
The invention relates to a PVC (polyvinyl chloride) product. The PVC product comprises 100PHR of PVC powder, 0.130PHR of plasticizer, 1-10PHR of stabilizing agent, 0-40PHR of modifier, 0-100 PHR of filling agent, 0-20PHR of foaming agent, and 1-20PHR of pigment. The method of preparing a formaldehyde-eliminating adhesive tape and rubber by using the PVC product is unnecessary to add the foaming agent when preparing the normal formaldehyde-eliminating product, the foaming agent is only added to the foaming product. A chitin is added in an artificial leather surface treatment layer; compared with the normal PVC product, the PVC product provided by the invention has the advantage of efficiently absorbing and decomposing the chemical substance harmful to a human body in the formaldehyde and latex paint escaping to the air.
Description
Technical field
The present invention relates to a kind of PVC goods and use its preparation except the method for formaldehyde adhesive plaster and rubber.
Background technology
Existing fitment material for family comprises that paint, coating, sheet material etc. all contain formaldehyde, and formaldehyde has strong carcinogenic and tumor promotion.Formaldehyde is mainly manifested in the aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction to the impact of HUMAN HEALTH.Its concentration reaches 0.06～0.07 mg/ m in every cubic metres of air
3The time, slight asthma will occur in children.When formaldehyde content in indoor air is 0.1 mg/m
3The time, peculiar smell and sense of discomfort are just arranged; Reach 0.5 mg/m
