Embodiment 1-3

[0077] A formaldehyde-free and odorless PVC foam board, comprising raw materials of the following quality: see Table 1 below.

[0078] A kind of formaldehyde-free and tasteless PVC foam board of table 1 embodiment 1-3

[0079]

[0080] The processing method of the above-mentioned formaldehyde-free and tasteless PVC foam board comprises the following steps:

[0081] 1) Carry out automatic batching and weighing of each component according to the formula requirements, manual weighing of small component raw materials, and automatic weighing of large component raw materials in the weighing system; accurate to 0.01Kg, under stirring conditions, according to the principle of adding PVC main Put the raw materials into the hot mixing pot, then add calcium carbonate, and finally add other raw materials in the formula amount. The mixing amount accounts for 60% of the pot volume. The synergistic effect of the high-speed stirring with the angle knife makes the temperature of the raw ma...

Abstract

The invention provides a formaldehyde-free odorless PVC foamed sheet and a processing method thereof. Compared with the prior art, on the basis of a calcium-zinc environment-friendly formula, siliconoxide and zeolite are applied to a PVC foamed sheet formula, and the formaldehyde-free odorless PVC foamed sheet is researched and developed. Moreover, a corresponding production method is designed according to the characteristics of the formula. The formaldehyde-free odorless PVC foamed sheet provided by the invention is free of formaldehyde, has a remarkable formaldehyde absorption function dueto molecular sieve structures of silicon oxide and zeolite, can be widely applied to the fields of indoor furniture manufacturing, wall decoration, advertising bathroom accessories and the like, and improves the ecological environment-friendly performance of furniture boards.

Description

technical field [0001] The invention belongs to the field of PVC foamed boards, in particular to a formaldehyde-free and odorless PVC foamed board and a processing method thereof. Background technique [0002] As people have higher and higher requirements for the living environment, people begin to pursue more novel decoration and building materials, which can not only bring the gorgeous appearance, but also reflect the versatility of the living environment, but it is these novelty The decoration of indoor air pollution is more and more serious. Among these indoor pollutants, formaldehyde is the biggest threat to people's health. Therefore it is urgent for how to deal with the harmful gas of formaldehyde in the indoor air and purify the indoor air. [0003] At present, the method of activated carbon adsorption and enhanced ventilation is used for indoor formaldehyde after decoration, which belongs to the method of physical adsorption in the later stage, and does not solve t...
